There is a lot of trial and error until que get the results we want to be able to publish an scientific article and share with the scientific community. I really love your channel and when you started talking about what were your plans, what you found out and using science to help you, it combined two things I really love: hair and science. Hope you get your results as soon as possible ☺️

That would be amazing if you could create damaged extrensions from healthy ones. Mechanical damage from brushing, chemical damage from bleaching, or uv damage etc. The top damage variations, and you just separate them and testing which damage repair threatment treats better those tipes of damages. That would be an extraordinary experiment!

At first this is the route I actually thought abbey was going with it! So, I agree, really cool idea! But, I’m glad you’re going this route first because I think it helps give you a baseline for hair health and which product does best at which baseline. And then, dive deeper from there! So cool.

Your findings of the cuticle being stripped thus, preventing the hair from being properly repaired is definitely mirroring my experience. My ends were so damaged and I’ve been using bond repair treatments with no results so I recently cut off about 5 inches. Now I’ll continue to use the treatments just to prevent damage that severe!

This is fascinating ! It would be great if you could test the strength of hair instead of the cuticle because this is what bond repair treatments are supposed to improve. And for the cuticle, see if there are conditioning treatments that can create a cuticle replacement when there is none or make it lay flat when it's lifted. Like Virtue, some cationic surfactants, things like that. I'm so excited ! Thank you so much for your hard work

Yeah. I love the idea of a tensile strength test. If they are repairing at the cortex level youll see it in a strength test but wont see it at cuticle level.

[@rationale7727]

Love your mindset in wanting to understand hair at a scientific level!! Even without cuticle, highly damaged hair probably still benefits from bond repair to prevent breakage, and possibly to have better structure to hold more shape in a style, which looks much better. Even though your samples don't look like gorgeous shiny hair, they DO look better than before. I recently treated my hair with K18 because of you. I had purchased it awhile ago, but didn't see or feel much improvement after 1-2 uses, and REALLY couldn't go without conditioner as its directions state. But after watching your video, I applied it for 4 minutes, then added a bit of water, then used a Moroccanoil mask (rec'd by Blowout Professor), rinsed and conditioned, then used Living Proof Bond Repair for 10 minutes, then applied Pureology Color Fanatic leave-in, then a styler with heat protectant (Color Wow Xtra Large), then used a blow-dry brush to style. It's a freaking lot of products, but I did see a HUGE improvment in my hair's health & appearance after about the 5th use of the K18 + Living Proof bond repair. (Also, I saw much better results w/ K18 after skipping the oil pre-shampoo, and washing the mids and ends a bit.) I would never have tried all the steps if I hadn't learned that strategy from you. Have you ever heard of science-y hair blog? science-yhairblog.blogspot.com/ Wendy is a scientist with curly hair who wanted to understand hair care scientifically. She has a lot of hair-under-the-microscope photos on her blog. It's very cool to see, for example, which oils protect the hair most from swelling during water exposure. One last random tip - if you use K18, when you can't pump any more out, break off the top of the pump. I got my husband to do it for me, and got 2 more uses out of the bottle.

@@e.4124 I have been using Olaplex conditioner, because I already had it before all this recent research. After I finish it, I plan to try Blowout Professor's rec for my medium hair type, which is Redken Volume Injection. Thanks to Abbey, I tried the K18 AND a mask AND a conditioner AND Living Proof Triple bond repair AND a leave-in conditioner AND a styler, which I would never have thought to use all on the same wash day, but it obviously works for her hair lol! I have used Olaplex conditioner for a long time, and by itself, it did not prevent me from having dull, frizzy, shapeless hair. And at times I thought it was too heavy and building up on my hair, yet my hair seemed dry. Well, as soon as I used the Redken Volume Injection shampoo, it was like a miracle! Getting my hair truly clean made a huge difference. All these %^&* "sulfate-free" shampoos were not cleaning my hair.

This is awesome, thanks for going through all this.

Also: thank you Chemist friend and fiancée! You’re both super appreciated

[@CherryBerry383]

I've been wondering about this as well! I've always used Aphogee's monthly/bimonthly, so I don't plan to stop even after starting Epres. But I'd love to know the effect proteins have on a non-existing cuticle

[@AbbeyYung]

Hmmm... let me see if I can find any existing research on this. Conditioning treatments really just create a film over the hair which acts as a protective layer!

I finally bit the bullet and purchased the Dyson AirStraight. I wish I hadn't waited so long. Trying to use a blow dryer and round brush, just resulted in puffy frizz. I thought the Revlon One-Step round brush would be the answer, but I feel that it really damaged my hair from the tension and by how hot the central core of the brush got. So, the AirStraight has been the perfect answer. (Perfect with the exception of the price 😢) I don't feel any tugging on my hair and I'm actually able to dry my hair using the middle heat setting of 230°. I have also seen improvement using K18. I am hoping that by using both, I can eventually get my hair back to a healthy state. Thank you for all your work and thank you to the individuals helping with your experiment.

hi! preclinical drug discovery researcher here- while the new samples you shipped to SEM friend has cuticles but just in case your hair samples aren't from one source (which might've been the case with your last experiment, the control strands look different visually)... you can mix the whole batch up (that means all the hair you've gotten from this purchase), really mix everything up and create your own strands. also with the products did you follow the product instructions (for example, living proof would let you use conditioner first) or are u keeping it all the same? also, let me know if you need help with other aspects of study design!

Oh my gosh. About 5 years ago I had a pixie cut and someone at the hair salon thought it would look good blonde. It was bleached to the point where my hair was gummy. Like it was truly horrifying. I lost like half my head of hair to breakage. Just snapped off at the root. This product doesn't exist anymore I don't think but the L'Oreal Professional Pro Fiber repair kit saved my hair. Obviously I had to grow it out to get truly healthy hair again (thankfully it was a very short bob at this point) but this product made it so that my hair felt like hair again. They discontinued it because one of the products made your hair feel a little weird while it was in (but you could wash it out 24 hours later). I wish it was still on the market cause it truly saved my self-esteem at that point in my life from having the most damaged hair even my new hair dresser had ever seen lol.

Very interesting and useful experiment. The fact the cuticles were completely stripped off was new info for me and something that explains a lot. My hair has been bleached so many times that it is probably either that or close to that over large parts of my hair. A lot actually broke off about 10 cm from my scalp (some of it as close as about 3-4 cm) and I was not a happy camper... Took it back to dark brown and now I don't touch it with anything but repair. K18, Olaplex (in the beginning it was so fragile I could not use K18 at all, but Olaplex worked wonders), deep conditioning shampoo and treatments + protein treatments. It's a whole thing, but this video confirmed for me why the bond treatments doesn't work as well as before. My hair is just too damaged. But I have to say it does help a whole lot, just not like before the disaster that broke the blonde experiment. ;) Can't wait to see your next update!

I hope this is just the beginning and that you will continue analyzing hair with various forms of damage. Analyzing and comparing different hair structures with damage would be interesting too. I'm really looking forward to finding out what works. I don't bleach my hair, but I box dye my roots every three weeks, blow dry, heat brush, use heated rollers and occasional curling iron. I use Nutrisse hair oil (which my hair loves), and occasionally use Olaplex. I don't really know if it works or not, but my hair is now almost to my waist and I previously couldn't grow it past my shoulders. Was it the hair oil? Was it the Olaplex? So much to learn. I really look forward to your videos, and now there will be so much more! Thank you!

As a fellow fifth year PhD student I do question why chemist friend did not provide photos of a positive control 🤔

[@Hotflash247]

I did a big cop 2 months ago 6 inches because of the damage. It was hard. I also have hashimoto disease, and when my thyroid is off, my hair shows it and my waistline. I am trying your hair was products, I am using not your mothers bonding line, it's cheaper, but I did order apres. Can't wait to play and see what happens ❤.

[@AlaskanGirl75]

Can’t wait to see the results! Are you drying the hair between each treatment? Or one after all 6 treatments?

[@heathermccuin9555]

I have super fine hair that probably lacks a medulla layer, and with your new insight, I think the cuticle has been stripped away - so I am just walking around with my cortex hanging out 😮! Bond-repair products and keratin-based repair products cause my hair to feel stiff and brittle, and I feel like they only increase the breakage on my hair for some reason, perhaps because I lack both a medulla and cuticle?

Thank you chemist friend and chemist girlfriend 😘

[@PopeEsVa]

I hope the brands won’t silence this info… I’m looking forward for the second part

[@dillin16]

I LOVE this combination of hair and real science, omg 😍😍

[@gabrielemcnicholl6174]

Thanks for the Sience dude. 😊 Nice that he is doing that for you. I bet all those companys you are using those bond repair products out from are breakin out in a sweat now. They all want to be the best of course. Can’t wait to see the next video ! I really want to know wich one is getting the medal.

So basically there’s no point in buying these products if you have bleached or highlighted hair? Isn’t that the purpose of these products? I feel like their response was one to make consumers just buy their products. 🤷🏼‍♀️

[@linaaaglaz]

Pls add a “control” hair strand without treatment this time, so we can see if there’s actually any improvement on a microscope level

[@MK-ih6wp]

YES PLEASE

[@KScott913]

Abbey!! Thank you so much for doing this and reaching out and connecting with chemist friend/thank you chemist friend’s fiancé!! I freaking love science and data and I’m so happy you are doing this!!

[@donnabuckner2689]

Thank you, Abbey and Chemist Friend! I can't wait to see the results!

[@delrio4222]

Love this video. Also, love that said thanked the woman for gifting “chemist friend!” 😂😂😂 Abbey is hilarious.

[@karikelly2797]

This is interesting! I would also be interested to see how bond repair pretreated unbleached hair fares against bleaching compared to non bond repair pretreated hair that is also bleached. In other words, how much damage does k18 or similar products actually prevent when healthy hair gets bleached? Two samples of healthy unbleached hair. One set pre-treated with bond repair and the other left untreated with bond repair. Both samples bleached. How well does the bond repair protect the hair during and after bleaching or is it damaging to hair equally and no matter what? If bond repair treatments turn out to not be actually restorative, is it at least preventative?

[@theocbeautymd]

Abbey, please update your color formulas. Your hair is gorgeous!

[@Kazzam46]

Thankyou, but i can't find the update video - has it been done yet?

[@marthedelaere5510]

Is it necessary to use a bond repair if you don't bleach your hair nor use heat on it? Can it benefit natural in some way? Love your content, have been binging it all, however this question came to mind :). Thank you Abbey!

[@MK-ih6wp]

Good question. Do you get highlights or dye it at all? I wonder if it can help w sun damage.

[@ducklingscap897]

I might be a poor student but the hair care nerd in me loves your videos enough to want it fund this endeavor 😂Thank you for all the hard work you are doing. I know it’s not much but I hope it shows that I really appreciate your content. Your videos really mean a lot to me. After a lifetime of hearing from my family members that long hair just isn’t in the cards for us due to bad genetics I found the motivation to try to grow out my hair. And I surprised myself and my whole family in the process :D

[@AbbeyYung]

Oh my goodness thank you so so much! and WOW. I absolutely love hearing this!! Keep me posted on your results as you continue your hair journey!!

[@iah8331]

ducklingscap, I feel like I have bad hair genetics, and it’s just not in the cards for me to have long, pretty, healthy, hair. I would love to hear about your journey. Thanks

[@briiee9751]

So excited to see how this goes

[@lydiatheglimmermaid]

What if you do a strength/elasticity test on the first set of extensions to see if there’s a difference there? I am not aware that bond repair does anything for the cuticle-I thought it was all internal strength and elasticity.

[@hebepena3220]

Abbey, with this video, you're taking content creating to a next level. I truly love how you steer your content creating career. Please keep up the good work, I'm off to watch part 2. And thank you to chemist guy and his fiancée, well done.

[@nataliamirochnitchenko8152]
