Rosemary oil for hair loss? How to spot bad science

Honestly, when people only have ONE study, that already raises red flags. For something to be concrete, its results should be able to be replicated in other studies. If there's just the one, and it's from almost a decade ago, I'm gonna take it with a grain of salt.

[@LabMuffinBeautyScience]

Yes! I came across a few doctors saying this on social media which was really nice (in between all the doctors promoting it...)

[@agiles6483]

I have to credit my professors for making me suspicious of research that does not have evidence of repetition by unrelated researchers/unrelated research sites getting similar results. The paywall issue is real, because abstracts may be the best writing the research team did.

[@pannajohns5255]

Reminds of the study homophobes love to use to convince people that queer people are not suitable parents, which apparently ‘showed’ that ‘Lesbian couples are more abusive towards each other compared to heterosexual couples’ and they always use this ONE study to *back it up*. Funny thing was, you can tell these people are not academics, I have read the academic source and it has never claimed that DV is more common in lesbian relationships, what it DID say was that lesbian women (and bisexual women) are more likely to have experienced DV THROUGHOUT their lives, that includes abuse from previous male partners and abuse from family. It also showed statistics that these women have experienced abuse mainly from the men in their lives. People really just go with what’s popular on the internet

[@turnbacktime65]

Agree 100%! And a double blind study or two would be nice.

[@sameerakhan7455]

Exactly. For such a referenced study, it doesn't seem to be reliable at all. Especially since this data is most likely quantitative so other studies could easily be done to check if the initial research conclusion was indeed correct or not. This is always the first thing I find suspicious, especially on the internet (Besides just saying a study and not even specifying it which I take as absolute BS), when only ONE study is referenced time and time again. It's just unfortunate it came from "trusted" individuals so if I'm being honest, if not for this video, I would've let the rosemary oil study go and believe it is true (Even if my initial reaction is disagreement on it actually working) so I'm glad I stumbled on this video, especially since most of the people shown pop up on my shorts

You’d be surprised. One of my colleagues in undergrad research had to present a paper at a major conference (entire northeast) which stated that they could not replicate results of a peer reviewed paper, following methodology in the paper (not suspicious in and of itself because it might come down to a minor procedural difference or specific chemical supplier) and could not, over the period of a year, contact the original researchers to troubleshoot or verify their procedure (big red flag). Reviewing just means that someone looked at the methodology and data and it “seemed” to be in keeping. Reproducibility is the real proof.

My dandruff is almost 100% gone and takes a long time come back. I used to wash my hair every day because it was so bad but now I can wait a few days before I do. And now that the dandruff is not blocking my hair follicles my hair can now grow and has gotten really really long. So rosemary didn’t grow my hair having a healthy scalp did.

The study was done in reaction to reports that hair oiling works, it didnt start the craze. Indian and pretty much all Middle Eastern cultures practice hair and scalp oiling. We oil our hair because of culture, not because of some study that happened in modern times.

Essentially those seeing results are only seeing them because they have been duped into taking care of their properly by using an oil in this case the "miracle cure" rosemary oil. But it could have worked with a different oil being used just as frequently.

Yes that's true, but the point of the video is to show, that there is little to no evidence for ROSEMARY OIL working specificaly. I'm sure there are a lot of oils that work, maybe just not rosemary

Yep, I think its probably because Indian and Middle Eastern cultures have a culture of taking care of their scalp and hair by using oils, massages, etc. So when you only take the oil from the practice but dont have a healthy scalp or anything else it will not work.

This shows that even "experts" are not infallible. Dermatologists are absolutely the best source when it comes to getting information for overall skin health and improving skin function, but that doesn't necessarily mean they know how every active used on skin and hair work, or how they behave in specific formulas. Cosmetic chemists don't have the same extent of knowledge on skin itself, but they're a necessary check and balance for dermatologists, and can give more insight when it comes to actual products and ingredients. I'm not remotely shocked that "skinfluencers" with no credentials didn't look into the Rosemary study, but I'm a bit disappointed at how many social media derms ran with the myth 🥴

[@LabMuffinBeautyScience]

I asked a few derms about why they think this happened - it seems like the training on interpreting new evidence is very variable for doctors. So while some doctors participated in journal clubs or are used to reviewing the literature, others assume that if it's in PubMed it's automatically legit. It's a really difficult situation for consumers - it's hard to work out exactly what different expertises are (before talking to the derms I thought medical doctors all got trained in assessing the literature!). I don't know what the best solution is.

I am prone to developing a lot of dandruff, especially during colder months and the rosemary tincture has kept my scalp clean and happy, which also helps with hair growth due to the reduced oil and dandruff production.

[@meltedsnowman9637]

Something to also consider is that based on other studies on 2% minoxidil, this study showed WAY less hair growth on 2% minoxidil over 6 months than we normally would expect 2% minoxidil over 6 months to give. This makes the constant comparisons in efficacy of rosemary oil to minoxidil 2% that people make based on this study even more dubious due to minoxidil 2%’s strange underperformance in this study compared to how it normally performs.

[@LabMuffinBeautyScience]

Yes! Although there is also some talk about how some of the other components in minoxidil formulas might be causing growth too - I came across some discussion about propylene glycol, but I didn't go deeper down that rabbit hole (it was a sub-rabbit-hole already)

[@meltedsnowman9637]

@@LabMuffinBeautyScience Tbh my suspicion was that they weren’t even applying the 2% minoxidil correctly in this study. Usually we would expect to see about a 20-28% increase in hair counts in 2% minoxidil over 6 months and a 26-32% increase in hair counts of 5% minoxidil over 6 months. This study only showed a 2% increase in hair counts on minoxidil over 6 months. Rosemary oil showed a 6% increase in hair counts over 6 months. That’s why it’s misleading to say that rosemary oil showed similar hair growth to 2% topical minxoidil. On top of this being both an extremely poor quality study with a lack of replication, unlike the studies on minoxidil which have been both high quality and replicated, even in this study rosemary oil showed just a 6% increase over 6 months compared to 20-26% with 2% topical minoxidil over 6 months. That’s why even if this study’s rosemary oil results were accurate, the 6% increase would STILL be way less impressive than the 20-26% increase we see in high quality studies on 2% minoxidil. Also minoxidil foam doesn’t contain propylene glycol and people still seem to get good results from it. So I don’t think this is due to a lack of propylene glycol as that wouldn’t explain an only 2% increase in hair counts on topical minoxidil. I’ve also never heard of propylene glycol causing hair growth before and I’m fairly familiar with hair loss research. They may have simply just been putting it on their hair rather than applying it to the scalp, and they may also have not been massaging it into their scalp like you’re meant to do with topical minoxidil. Considering how low quality this study was this wouldn’t surprise me if this was the case. They may have not told the participants to apply it the right way or even told them to apply it in an incorrect way, whether intentionally or unintentionally. They also don’t specify where they applied the minoxidil so they could have been applying the minoxidil to a place not even affected by androgenetic alopecia.

@@meltedsnowman9637Hi I was wondering if you could perhaps help me. I have an issue with hairloss, I have been suffering from male pattern baldness which starts around the temple and have been taking minoxidil 5% with okay to good results, I was wondering if this will be a lifelong commitment, like if and when I stop it, will I get back to my bald self? Also, can I up my dosage of Minoxidil to around 20%? I am desperate for my hair to grow back because I am only in my early 20s and people think I'm already 50. Thank you.

[@princessmimithepug6719]

The problem with minoxidil is once you start using it you have to keep using it forever because if you stop all the new hair falls out. When I lost my hair the specialist recommended rosemary oil first before looking into chemicals. So I bought some and actually over 2yrs it's helped so much I have almost regrown my hair, but like anything it works for some not for others. I lost my hair due to stress but I definitely don't think rosemary oil would work for alopecia and mpb etc and I think it's wrong to give people with those conditions hope.

[@dalailarose1596]

​@princessmimithepug6719 You would have lost that hair anyway tho, because you were already balding. So of course you have to keep using the medication in order for it to keep working. That's... how treatments work. If rosemary oil worked, it would work exactly the same way. If you stop treating hair loss, then yeah, you lose your hair again.

Many practicing pain management doctors have very little understanding of the actual functioning of these medications, to the point of some clinics expelling patients when smaller quantity metabolites of the very drugs they prescribe show up in patient urine once the patient dose is increased. Edit: With that said, I'd be absolutely up a creek without a paddle when it comes to clinically treating people. Main point, MD and PhD are different pursuits with different strengths.

FWIW, rosemary oil isn't a BAD option for someone who cant/won't use minoxidil. Massage with rosemary oil stimulates circulation, dislodges trapped debris & moisturizes, so it's not entirely without benefit. The paper these people are citing doesn't prove its claim that rosemary is comparably effective-- but that doesn't mean that Rogaine is the only way to go. I would recommend clients start massage & scalp skincare before referring them a drug

[@XOChristianaNicole]

@@margodphd- It’s worth trying before going the medication route. Not everyone’s body can handle medications - such as myself. And it isn’t always easy, for everyone, to find a doc who’s gonna be knowledgeable in this area of expertise - or, perhaps, they do not have the financial means.. There are so many reasons as to why going to a doctor isn’t a person’s first thought, when dealing with hair loss. For example, as a former hairstylist who specialized in men’s cuts, men aren’t as apt to go to the doctor, in general - and especially for something such as hair loss. Perhaps more men are becoming open to it, nowadays, though, in my experience - they tend to not be. Yet, men tend to REALLY trust their hairstylists. Many will tell their hairstylists things, more than they will their wives. Hell, some men are more committed to one hairstylist than they are their own romantic partner (obviously, I am not referencing in an inappropriate way). It isn’t our job to diagnose anything, correct. Though, it is our job to recommend things we think might be worth trying to solve whatever issue One may have around their hair, within reason - while, of course, the client knows to follow whatever recommendation under their own discretion.

And let it sit, for an hour or so. And after washing it out, my hair feels AMAZING. Sure, I use some of the top of the line hair products, being a former hairstylist, myself - though, sometimes, my hair gets weighed down, from the silicone. This gave my hair body and volume, even when using both shampoo and conditioner with silicone (I switch between Pureology’s Nanoworks and Hydrate Sheer line).

My PERSONAL experience, is that rosemary oil DID make my hair grow and stop falling out.

I would apply the oil and massage it in with a scalp massager every single day and I still do. And my hair IS growing faster and fuller and thicker. But I think it’s from using the massager. To confirm it’s not personal bias, people who didn’t know I was doing this remarked on how much fuller my hair has been lately and asked what I was doing to make my hair so thick.

When I was at university (linguistics), we were taught to read the abstract first to see if the study is applicable to what you're researching, then the results, then the conclusion/methodology (it's been a few years, I can't remember which came first), and then the introduction. You were taught to basically never read it in order and to never draw conclusions from the abstract if you didn't see the results. I had assumed that that was being taught across all disciplines, especially the ones focussed on science and research...but I guess not! Either I had good lecturers and a better uni than I thought or some people weren't there for when their lecturers told them to not do this. Regardless, I think it should be more common knowledge and taught more widely, because that not only helped a lot to work out what I was looking for when I was doing research, but it also made it so much quicker because I wasn't reading the whole study like I was before! Although now I'm not in uni I have to just guess with the abstract because I can't access the journals for free through the university library anymore 😭 Edit: I just can't get over using a rating system for depression as a measurement of hair loss. Like I keep trying to work out if it was a mistake or if they actually quantified hair loss by asking if someone had been feeling down for more than half the last week. I've had to take those kinds of screening/rating systems a lot as I have mental health issues and no one has ever said if my hair is good or not after it! I want to go back to university at some point in the near future, so I'll make sure to include a rating system for OCD when discussing phonology and see how much my lecturers agree with my methodology. I'm expecting full marks.

[@LabMuffinBeautyScience]

I've been taught that order too! I think it's a bit harder to apply that if you aren't already somewhat familiar with the area, so my strategy as someone who reads a wide range of papers is to read it in order, but don't trust a single word from the abstract, intro, discussion or conclusion until I've cross-checked against papers/reviews/textbook chapters from the leading researchers in the field. They actually used the balding scale in the paper, but wrote "Depression" in the methods... which is absolutely bizarre? I can't think of how that ended up in there - it's like an autocomplete mistake, but the paper was published in 2015. Maybe they paid a history undergrad to write it up?

[@MissaBrevis]

I was taught the same reading order when I was in college for chemistry - as part of the same seminar we talked about journalists misrepresenting studies and some of the common signs of academic fraud, and just generally building the skills to tell good science from bad.

Peer review is really tough and I'm proud to say that at least at our journal when we see half-assed reviews coming in we start asking additional people to review the paper so we are a little atypical in that regard. It has been obvious to us for a while that our scrutiny and attention is somewhat above the industry standard but then again we have a pretty good impact factor and we take our job of distributing good medical science seriously. I think you should write a letter to the editor and directly criticize and challenge the paper. There's too many mistakes, and they need to defend it. Maybe retract it.

I tried minoxidil for about 6 months. Not only did it not help regrow any hair it completely fried my scalp. I had sores and it gave me horrible dandruff for quite a while from all the dead skin that was fried off my scalp.

[@Erideah]

Glad you're covering this, I basically just glanced through the study and conclusion after I first heard about it and went "uhh this is really baby stage stuff". Worries me when I see doctors cite this sort of thing as a basis to say it's comparative to minoxidil, but thankfully a lot of hair specialist doctors weren't as enthusiastic about this

[@LabMuffinBeautyScience]

It worries me too - I've seen a few doctors on TikTok say they recommend this to their patients...

[@4amlibra]

6:19 I paused and read the abstract, and that last line killed me: “The findings … provided evidence with respect to the efficacy…”. This trial resulted in… results.

[@theultimatesvengali4430]

may not work for everyone but it worked for me! I tried it skeptically but noticed a huge improvement

[@itsgonnabeanaurfromme]

Edit: just forgot to say THANK YOU for this video and all your efforts! Many people, including myself, appreciate you deeply. Just finished the video. Honestly, I'm not surprised at the study's flaws. There has been plenty of scientific dishonesty in academia. Just this year, that Harvard neuroscientist got exposed and even I know of people with allegedly (but apparent) cooked up data.

[@LabMuffinBeautyScience]

I've been glued to all the academic drama - Elisabeth Bik is a hero (she followed me back on Twitter, I was so chuffed!)

[@LoveratLoves]

Because in order to ensure funding they need pre-ordained results.

[@itsgonnabeanaurfromme]

@@LabMuffinBeautyScience I LOVE her. Academic dishonesty is the worst but ever since BobbyBroccoli's 3 part "How to Lose a PhD in 127 pages" on Jan Hendrik Schön, this is the only "drama" I eat up.

[@itsgonnabeanaurfromme]

@@LoveratLoves sometimes yes but also many times, they just want something that is statistically significant. The problem with academia is imposition of requirements to publish and the problem with publishers is they only want novel data from big names.

[@LabMuffinBeautyScience]

@@itsgonnabeanaurfromme I love Bobby Broccoli! It's so impressive how he makes footage of a chart so engaging, I could never

Great video as always! Ive been using a combination of rosemary oil and peppermint oil for over a year now (add it directly in to my shampoo). It reduced my general hairloss visibly within the first weeks of use. My hair grows faster too. My family members and friends have similar experinces. Those who had dandruff issues, dont that issue anymore. Might not work for everyone. Dont know about hair *regrowth* after major hair loss tho

[@LabMuffinBeautyScience]

I discuss the reasons why anecdotal evidence isn't reliable for hair loss specifically at 17:00, and generally in this video kzbin.info/www/bejne/b32Tq3ukrad1irM

[@toaster9562]

@@LabMuffinBeautyScience I know. Youre right. I know that with "natural remedies" it might work for one person but not the other. I just wanted to share my personal experince since everyone here seems to have no positive experince with rosemary oil. Maybe i shouldve fomulated my first post different to make it clear that im not speaking against what you said. (it's not my native language)

[@volterstara2641]

Hey, love the content! Could you make another video about hyperpigmentation, acne spots, scars, etc? :) The one you made before seems to be unlisted or deleted😅

[@LabMuffinBeautyScience]

Oh yeah, I had to delete it because of Australian sunscreen regulations! Probably needed an update anyway 😅

[@whoever57]

The 'Never trust an abstract' in the background is just the cherry on top in this beautifully educative video.

[@-beee-]

I LOVE this. The guided breakdown for reading a paper was excellent. Would love more of this critical reading of research content!!

[@alik2062]

I started using homemade rosemary water on my scalp just two weeks ago and now I see this video 😅 But I have to say, it really helped me with sebum control. I wont be able to say if it helps me with hairloss, since I didn't measure the amount of dead hair falling out or how fast does my hair grow naturally.

[@devicetablet9305]

It’s always takes a month to start showing up. Be consistent

[@alyaaamir1594]

I did the same and boiled ginger with it for 2 months, it actually helped my hair a lot. I've noticed more growth and it reduced my dandruff to almost non-existing

[@winfieldhaslam6292]

Many moons back when I was in Orgo lab, we were doing essential oil steam distillation and, scrambling the day before, I grabbed bags and bags of rosemary growing uncontrollably at one of the student rentals, simply because it was abundant and, well, there. Seeing the numbers for the daily amount gave me a flashback and a good laugh; I was jamming SO MUCH ROSEMARY throughout that entire day, for literally a drop or two when it was all said and done after a 9 hour lab. After a career pivot, I’m now a stylist, and seeing videos of someone casually boiling a few sprigs of rosemary with a lemon wedge on their stove top, and then sprinkling it on their head, shouting praise of it’s ~magic elixir~ benefits, sends me to no end 🙃🙂🙃 Excellent as always, Michelle!!!

Oh my God 😭

[@duckyducky7082]

Lmao

[@mandeekeefer6151]

I do not know about it working as well as Minoxidil, but I do know it works, at least for some. I am not certain it is a fail safe for all hair regrowth. I have been using it since September 2023, I have my own I make its just rosemary essential oil and almond oil, and I have had a lot of regrowth throughout my scalp. I have seen hair come back in areas where it has been missing for about 10 yrs. So yes, it does work. Will it work for everyone, I have no idea.

[@artiste9357]

I love how simple and digestable you made all the information and as a noob, even I'm shocked at how this paper was approved and quoted so many times too!! Sidenote, of course YT recommends this video right after I purchase rosemary oil lol

[@CandyGirl44]

There are some well known KZbinr doctors recommending rosemary essential oil🤔 Personally, I tried castor oil, hated the oiliness, didn't seem to make a difference so am now on rosemary and sesame oil. I honestly don't know if its the actual massaging that is helping, I'm doing it only once or twice a week so not enough to be scientific, but my hairdresser has said the bad cowlick on one side of my forehead has definitely improved, and I have heen able to go back to a central parting. I'm over 60, my hair has always been fine and thin, so this will be an interesting anecdotal experiment for me for a year.

[@G0shaKarr]

My sister and I have PCOS and we both deal with hair thinning caused by it. I use 5% minoxidil but she prefers natural things, so she uses that Mielle hair oil. I guess the massage is what helped her because she did get hair regrowth

[@cassie6985]

I wish I could say this in a way that doesn’t sound overly sentimental but I got really into your videos in 2020/21 and I didn’t realize how much comfort they brought me during that time until I clicked on this and it took me back, like when you smell an old perfume you used to wear all the time. You were like my hbomberguy of skincare/haircare science. Didn’t mean to stop watching, my algorithm would have to answer to that Ok now to actually watch the video

[@takotako3750]

Oh noo please not a minoxidil! I started it because of alopecia areata and as soon as I stopped using it I lost all the hair that regrew with minoxidil. As for oil like pepper oil rosemary and castor oil my hair started to grow inbold patches slowly but naturally and I noticed these changes in 3 month. Everything takes time and needs to be done systematically and in a right way

[@zoenightshade2332]

loved this video, you went over the peer review process so well. I liked the transparency, that's how good science happens

[@Linh-rv5dg]

I have mixed rosemary oil with shampoo before and my hair grew quite quickly. It might not work with anyone but it did work for me

[@Sinthecity]

Why did it work

[@ladyib2402]

How many drops of oil did you do in the shampoo? Because i want to try it too..

@@ladyib2402 I didn't really measure accurately. Just a splash (maybe few drops) into my shampoo

Help Please !!! Make a video explaining the pros & cons of applying heat to hair. I have very long gray hair, and let it air dry, bc it seems to get very dry & frizzy if I blow dry, but it also is extremely thick and to “tame” it, I would like to use my Corrale on it. I have become TERRIFIED of hot tools bc of all the literature I’ve read about the damage they do. I would love to know the REAL SCIENCE !! I trust your guidance and expertise in this matter.. My hair is extremely important to me, and I don’t want to risk damage. I am in my 60’s….☺️

[@mahachowdhury826]

So is it a placebo effect? Cause rosemary oil actually helped me

[@Poochipup]

I can't take minoxidil because you have to be on it for life, yet my hair loss is temporary. Apparently, once you get off it, all the hair falls out that you gained despite no longer having hair issues! So what else can work? What about pumpkin seed oil?

[@Cocoanutty0]

This was the best explanation for mechanistic reasoning and why we shouldn’t rely on it and instead look more at previous evidence and repeat testing using the same variables.

[@LoneWolf-rg8gz]

Rosemary doesn't work as well as minoxidil. but combined with peppermint oil it worked to grow back my hair that was thinning due to traction alopecia
