Ah! Love your videos! I got so excited to see you made a new one, thanks for all the work and effort you put in them. I kinda have an idea for a future video. Have you ever thought about trying to make diy scalp and/or hair masks that have a big chance of actually working? Something instead of cracking a useless egg on your head, baking soda 💀, or adding a bunch of humectants like you mentioned in this vid. I know this could easily become overly complicated (and that you’re a wonderful hair nerd and not a professional product creator) so I know this might be a crappy idea so sorry if thats the case.

@@Koki-hc3mw I want to be supportive of other women creators. Especially Black women. And even more especially when it comes to Black women and your hair. Your hair has significance to you in ways mine cannot. Black women throughout history have been and continue to be some of the greatest innovators in haircare, and you deserve to be lifted up and acknowledged for that. It’s not my place to argue or try to convince anything; I do believe ethically it is my responsibility to share the evidence we have from research, and you can do with that whatever you want and it’s none of my business. At the same time, I do feel I personally was misrepresented in that video. I have a Hair Practitioner certification from the International Association of Trichologists, which is the same place she got her Trichology certification. Since certifications are not degrees, I’ve never called myself an expert. The experts on this aspect of hair are cosmetic chemists; neither of us has a degree in chemistry, biology, a medical degree, or anything of the sort. I’ve consulted with cosmetic chemists both before I posted and after her video came out, and they’re in alignment with what I shared. Ultimately, I still think Afope is an incredibly intelligent, well-educated resource for hair knowledge.

[@SarahIngleOfficial]

@@Koki-hc3mw In science, nothing is ever proven. We take all the evidence we have at hand and make the best conclusions we can with that evidence. And when we have more evidence, our conclusions and views continue to evolve. Though I do absolutely think that we need more studies on Black hair, there is still a substantial amount of studies that either include it as one hair type or focus exclusively on it - especially more recently. Given all the evidence that we have, the experts, including Dr. Evans, currently conclude that this applies to Black hair, as well. He was actually specifically asked this question in a recent lecture I watched that he gave at TRI Princeton.

[@savannahbrewer6161]

@@SarahIngleOfficial not sure I agree with the idea that only black women's hair has significance. modern western caucasian culture doesn't attach much importance to hair, but other cultures do and it isn't fair to exclude them for not being strictly black. however, I don't think that's what you meant, I'm just pointing it out because I feel these things can get too polarized to come anywhere near the truth.

A lot of people on youtube are avoiding sulfates and silicones these days...especially people with textured hair.Can you maybe make a video about it? Is it really that bad for your curls?

[@laurieparis2203]

I've heard so many negatives about silicones, that they don't play nice with conditioners, by sealing the cuticle so that all the beneficials in the conditioners are basically locked out. So I'd be interested in learning more about that from you, too! Meanwhile I've got my litmus paper out and I'm testing my shampoo and conditioner. 😆

[@GillBilly98]

I know it's been a while since you posted this question, but I wanted to give you an answer based on my own experience and the experiences of my customers. It seems to mostly depend on your specific hair, I know they say that sulfate free shampoos and silicone free conditioners are the best choices for dry hair or textured hair. I have incredibly dry hair, and I actually feel that my hair felt more dry using sulfate free shampoos compared to when I used shampoos with sulfates. I use a combo of sulfate shampoos abd silicone free conditioner and that's the combination that works for me. I got one of my curly haired customers hooked on the brand I'm using that has that combination and it works for her as well. If you have fine, dry hair that might be the way to go for you because it seems like the sulfates seem to keep the hair light and free from build up, but the lack of silicone allows the moisture to better get into the hair shaft. Whereas if you have a thicker, coarser hair type those sulfate free options might be better for you. I recommend experimenting with different choices, if you feel what you're using now works awesome, great! Stick with that (although alternate your shampoos here and there because your hair does grow accustomed to it if you use it all the time), and if it doesn't, try different combinations to see what's best! There's unfortunately no one size fits all, but once you find the combination that works for you, you'll be so much happier! Sorry for the super long response, I just really like talking about hair products lol

Aloe vera is the worst idea. I have very thin hair and I put aloe on after I kept hearing how the haircare enthusiast people use it on the hair. And omg it's never been frizzier. Now I know why. I think that some people just have very good hair naturally, they're low-porosity and all that so those weird ideas don't affect them and it ends up making them think it works/is neutral. Kind of like those people who use straight up soap on their skin and slap Nivea cream on every day and swear it's what's keeping their skin clear and young, but their skin is just really resilient and they never had problems with acne to begin with.

[@raqueldj6]

Hi! I have a degree in chemistry and I completed a course on natural cosmetic and Sarah, you disseminated very well this information, we can see that there were a real research behind. Sometimes we overcomplicate things, the main function of a conditioner is to prevent water to enter into the hair when it's dry, for that a very simple solution could be to apply a little bit of oil (with low viscosity), like argan or grape seed oil, on your hair when it's wet. That way, the water on the surface will evaporate but the hair shaft will be "isolated" from the external humidity and it will preserve better its natural shape. Applying the oil when the hair it's already dry can work too, but you could already have frizz because your hair has absorbed water from the air and to correct that, you can wet a little your hair (to reform the H bonds) and apply the oil. Besides, that way your DIY product will only contain oil without any water and that will prevent pH problems and microbiological contamination ;)

[@RonjaSebastian]

*This is golden.* Thank you. I did something similar yesterday and it worked, and your comment just explained why. Normally I would apply leave in conditioner/curl cream first, and THEN add oil to try and "lock the moisture in". Yesterday after washing, I applied Rejuvenique Oil (very low viscosity oil) first, while my hair was still wet, and then I added the leave in conditioner, and my hair turned out so much softer, sleeker, shinier than usual. It confused me at first (I had thought "moisture/humectants first, oil/occulents second) but now that I read your comment I understand why it works: That way, the water on the surface will evaporate but the hair shaft will be "isolated" from the external humidity and it will preserve better its natural shape. Thank you!

@Sâ Ka Water is what jacks up the hair because it raises the pH and opens the cuticle which damages your hair and makes it look frizzy and "dry" (at least, that's what I understood from the videos). Oils and conditioners will be what makes your hair feel soft and look nice and shiny because they keep your hair's pH level where it should be, keeping your cuticles closed and therefore preventing the damage.

It took me 33 years of dry coarse hair plus thousands of dollars spend useless on expensive car*p from the industry and expensive treatments with no results, until I read a comment of someone using lemon. I do not use shampoo anymore, I just mix baking soda with lemon ( not for scap with eczema/psoriasis) to cleanse - it cleans impeccable ( no foam but after a few times I got used to it and will never go back to dirty shampoo chemicals) and after cleansing just soak my hair for 3 to 5 minutes with a squeezed lemon then rinse and the way my hair shines and gets lusty is mind blowing! Same like keratin treatment with only the cost of a lemon 🍋 the hair can be washed with any product and lemon juice can be used just as a conditioner, just squeeze the lemon, strain the pulp and seeds away and just apply the juice ( one or 2 lemons depending on the length ) and it will do magic! Only to be keep in mind the lemon has to be fresh as it's the oils in the lemon that do the magic ( one way to check is when cut, if the lemon juice is oily on the hands then it's good, if it's not that oily on the hands and gets easily away with water, then there will be no potency ) Nature always has our back for free! Also look into shikakai, kapoor kachli, reetha or bhringaraj powders, they are cheap indian powders used for centuries for healthy lusty hair!

Coincidentally, Michelle Khare and her fiancé Garrett invited me to play Among Us a couple times. First time, Kelsey was playing and I didn’t realize until afterward “Oh she’s the Sims girl!” 💀 There is a very specific Disney video that I’ve been working on that’s the biggest project I’ve ever had for the channel. It’s basically on hold right now because of the pandemic, though, so hopefully soon things clear up enough I can get to work on it more.

YOUR VIDEOS HAVE ANSWERED SO MANY questions that were not lining up! I would wonder why sometimes putting oil or serums on my curly hair without water would make it so much more manageable but I would also cringe because so many curly hair channels emphases using water basically everyday. Goes to show every head of hair has different needs and you should do what works for you. Thanks Sarah!

[@jessicaleep100]

Thank you for clearing up the hair moisture myth and explaining that PH is what really matters. This has changed the way I think about hair. I used to have so much anxiety because it all seemed so mysterious and I felt like I was taking shots into the dark. Plus all the pseudoscience and diy going on only made things more confusing. My fine wavy hair was always frizzy and felt cursed! The science of hair is really not that complicated, but has been made complicated by misinformation. Thank you!

This is interesting. I have fine wavy hair and a lot of it. Every time I use products recommended for curly hair that claim to moisturize I noticed my hair gets frizzy. Water also makes my hair frizz if I air dry so I blow dry. I just use it's a 10 miracle leave in and that's all I really need.

This is it, honestly. It's all about conditioning/using protein based on your needs while making sure not to overload. It drives me crazy when I see someone with frizz say they need more hydrated hair!! No just use a better sealant!!! I used to obsess with hair but recently I realised it's low porosity fine wavy and that it takes care of itself very well. Gentle shampoo+gentle conditioner and less brushing works well enough, anti-frizz product only when it's so humid that it would frizz otherwise (on the other side, "training' my hair to be less oily does Not work on my scalp! It gets oily d3 no matter what and that's fine!). Everyone's hair is individual and Ik that would not work someone whose hair damages easily or has high porosity hair naturally.

Former cosmetic chemist here (still a chemist, but I've switched industries). I think you hit all the important points in both videos.

[@consciouslypure2176]

Another great video! What about so called “deep conditioners”? So many people say that it’s crucial to do deep conditioning sessions for the health of the hair, but I have always felt slightly unsure. I found out that the difference between a regular conditioner and a deep conditioner is literally just their richness, so basically the oil to water ratio. Is it actually necessary to keep such deep conditioners in the hair for 30 mins? Does anything happen during that time that doesn’t happen right away when you apply it? I never notice any big difference when I keep a deep conditioner in for just 2 minutes vs 30 minutes. So perhaps all that is supposed to happen just happens right when you apply it! Also some people say that putting pure oil on the hair and keeping it on for an hour and then washing it away is supposed to be very conditioning for the hair. Does the oil actually do something inside the hair? Isn’t the whole effect gone if it’s just washed away? It would be great to hear your thoughts on this!

[@bomsnose]

from my own tests on my own hair, so sample size of 1😂 as long as your hair is fully of silicone buildup, like most people's hair is, it doesn't matter anyway. your hair isn't going to take up much of anything anyway. it's like applying pure vaseline (petrolatum) first on skin, and then wondering why the serums applied later don't get absorbed well. i quit silicones about 12 or 13 years ago, had to cut off much of the hair afterwards, as without the continued silicone supply it was just brittle, broken, split in the middle, etc. i did use (silicone-free) conditioners for a while, but eventually realized that even the olive oil lying around in the kitchen is a perfect pre-shampoo treatment that replaces conditioning on my silicone-free hair anyway. (allergic to pure macadamia or argan oil, those would be the best otherwise) i rotate through all sorts of random oils, whatever i feel like, rosehip seed oil, grapeseed oil, whatever is around. focused on the scalp and ends, but applying a bit everywhere. every year or so i test out eg. melted butter/oil/raw egg masks, they are a-ma-zing, like hairdresser asking you hair tips sorts of amazing. but it's messy, and i try to consume as little animal products as possible, so it's reserved for like the middle of winter when i need a serious pick-me-up. what i'm trying to say is test out a wider range of products, make your search wider. test stuff out for yourself. if you don't feel like it's doing anything, it's probably because it really doesn't do anything for you.

[@elyssabarajas3554]

Would definitely be cool to see a video on this!

[@katm8128]

I can’t offer any scientific backups or research, but I do know that keeping a small to moderate amount of oil an hour before I wash has made my hair silky smooth. It’s amazing. There have been times where it’s felt over conditioned because of it though and I had to take the shampoo down the lengths of my hair to cleanse it and get it feeling good again!

I have a lot of split ends.

I feel like there’s this idea in the hair are world that if we just use the right products or treatments that we can all achieve a shiny, soft, smooth, etc. look without any heat. I’ve come to the conclusion that while many products can help you get a little closer to waking up with that. It’s largely unattainable without heat styling with the exception of a lucky few. Awesome video!

[@SarahIngleOfficial]

Yes! Healthy hair doesn't necessarily mean looking like a Pantene ad. We all have different hair textures.

[@Fearless_Love_]

Should I exclusively use a wooden hair brush? Also in one of your other videos you mention not to twist our hair and I was wondering why not? What about the twist is damaging?

[@SarahIngleOfficial]

I think there are different meanings of the word twist. In the study I was referencing, it means twisting an individual hair strand. You can even test it out for yourself. Usually if you pull on a hair, it has a little give and stretches some. But if twist it a bunch (like a spiral staircase) and you pull, it’s way easier to snap it

[@sabrinachaney3151]

So would this mean that silicones don’t actually keep water from entering your hair? This confuses me because so many people say silicones make your hair “dry” and break because it doesn’t let “moisture” in?? Lol I trust your advice so I’m curious.

[@paige6094]

Okay so does porosity matter? I have seen a lot of videos on that.

[@waseabi5220]

based on this info, i think? high porosity needs more conditioning (to "flatten out"/seal the cuticles to help with the roughness and frizz) while low porosity needs way less of that, since it's naturally better at both. also you might get your own hair porosity wrong if you do those at-home tests. generally speaking it's probably best to look at amount of damage hair went through, and whether it naturally gets shiny.

[@skylarbix7912]

If you're bleaching your hair, it has high porosity!

[@cott.onwolf]

So what product would you suggest to keep moisture OUT of your hair? My hair has always been so ‘dry’ and course, and is very thick and frizzy.

Question..... does it really matter what kind of shampoo you use then as long as you use conditioner? I have dry hair do I no longer really need moisturizing shampoo?

[@howler9653]

Dose water damage my hair or is it the shampoo?

[@hannajung7512]

Its both... BUT you also have to clean your scalp to not get infections and your hair to remove build up. The worst damage is done to your hair by washing it, why the best shampoo for you is the one, that allows you to go as many days without washing as your skin type and life style allows for. If you have to wash daily, for hygene reasons (some professions make this necessary) or because of skin conditions, then your shampoo should be as mild as possible and the time you soak your hair with water should be as short as possible.

[@SarahIngleOfficial]

Hanna did a great job of answering for you! Yes, they both can be, but we definitely can’t avoid water, and we also don’t want to irritate our scalp, so we can be careful to choose a shampoo in the right pH range. There are products like New Wash that can clean your hair without detergent and it’s not technically a shampoo, but you occasionally may still want to clean with a real shampoo especially if you use a lot of hair products that may build up on your hair. Avoiding anything damaging to your hair is virtually impossible, but it’s still impressive strong. As long as you’re gentle with how you handle it - especially while it’s wet and extra fragile - you’ll be good to go! ☺️

[@Bloodyhands79]

Now I am a bit confused about hair masks and leave in conditioner: if it's true that my hair shafts don't need moisture to penetrate in with a hair mask, a spray leave in conditioner with the same main conditioner ingredient (behentrimonium chloride) will be effective as well as a hair mask. But my experience is that a spray conditioner can't do the job in the long term. If I don't apply masks my hair get more brittle and prone to break. I thought the moisture that a hair pack gives can make them more elastic so less prone to breakage. I have fine and curly hair.

[@mlizza]

Love how simple you explain everything

[@bibliophilecb]

I found you via your original “dry hair” video and ended up staying up late bingeing so many more of your videos, I love the way you present info in a researched, informative way that’s still fun to watch! So glad I found your channel! 💛 I do have a question though. A lot of curly styling techniques that I’ve found to work really well for me 2B-3A hair specifically involve getting water in the hair, emulsifying it with conditioner, and trapping it in. This includes the “squish to condish” method and adding oils while the hair is damp. My question is, does this “work” because the water in the hair is just keeping the hair in its natural state (like a controlled way to get the curls one might get in humidity)? Or does the water just help the conditioner to bind to the hair? Or is this something that is actually harmful and doesn’t do what it seems to?

[@SarahIngleOfficial]

Water breaks the hydrogen bonds in the hair, which allows the hair to snap back to its natural state - and when it dries, the bonds reform and hair holds whatever shape it dries in. So with waves or curls, those waves and curls reform and probably will look more defined - or you can scrunch the hair and make those waves and curls look even more pronounced. It’s more that you don’t want products that are designed to hold water into your hair. The water itself does the hydrating, and a big reason for that hydration is to break hydrogen bonds. If you have a product that literally hydrates - like a humectant like pure glycerin - that bond isn’t going to reform completely and your hair won’t hold its style as well. Since hair holds whatever shape it dries in, if it’s not ever entirely dry, all your moving about your day is going to keep messing with the shape and it’s probably going to get frizzy. Plus, hair is more fragile while it’s wet. People also ask then why do you comb or detangle curly hair while it’s wet? The more curly the hair, the greater the combing force. When combing force is greater than the strength of the hair, the hair breaks. You know how when someone with super curly hair jumps in the pool, it goes from big curls to flattened out from the water when they pull their head out of the water? The curls are temporarily flattened out from the water. Curls have such a strong effect on combing force, that even a little bit of straightening dramatically reduces that force. There are some other reasons too, but that’s a big one.

[@bibliophilecb]
