PLEASE do one with her about all of the bond repair treatments and the science behind them.

As a registered dietitian, I totally agree that social media is a blessing and a curse when it comes to finding information. Keep coming out with content that is evidence based and hopefully your voice will be louder than people that make opinion based recommendations. Thank you for speaking up!

I think the reason people, me included are suspicious of products is because of the exact thing she said about Brazilian blowouts. A chemical formulator somewhere created it knowing formaldehyde is cancer causing. And even though I know to look for formaldehyde, it might be under a different name that I might not know of and say formaldehyde free? 🤨 As a black woman who used relaxers that have this same ingredient for 20+ years, I shudder to think about the damage I’ve caused to my own body. It’s not like the box said “caution this contains a known carcinogen, use at your own risk.” These products are still being sold and used today. I will continue to do my own research and question everyone because history has taught me that it’s more about profits than safety for a lot of these companies. Also I rarely hear formulators address bioaccumulation.

I wish she would have talked about why is formaldehyde still allowed to be put in formulas. Saying that products on the market are regulated and safe but then saying "with this exception" shoots the argument in the foot.

LOVE your hair content! So refreshing to see scientific based hair care that makes sense. Very welcomed in the ocean of fear mongering bullshit « clean » stuff we get constantly. I am sooo fed up with the « natural/clean » thing. It’s a real cult thing only based on hair mythology, and making people feel scared and guilty and not helping them with chemistry/science education, with a huge dosage of greenwashing. honestly, the « clean » thing has become pretty unhinged and ridiculous

Ohh I love this! As a trained cosmetic chemist myself I am really glad to see this type of information on the internet. When I started studying and realized that basically 90 % of information which I thought was valid was actual nonsense. As companies tend to just go with the flow and give the costumers what they want based on the bulls*** info they have you still see a lot of sulfate- or silicone-free stuff. Or even moisturizing, which is nonsense. As I also worked in industry (which I do not anymore) I got hate while trying to educate people on the real science, especially by people who blogged a lot about hair care ingredients. People thought that of course I am biased as I am interested in the sales of the company I worked in and thought I spread misinformation. Because... you know, people know better after researching for 2 hours vs. me, who worked in industry as i underwent several years of basic chemistry training before specializing on cosmetic chemisty.... I also sometimes feel the more educated in the field you are, the less actual advice on products you can give, as there is a loooot of possible parameters which affect formulation. I think Anna had the same thoughts on this. A weird effect I noticed is that I went back to using haircare without diving too deep into the ingredients list as now I know that there is too much to consider which you can not see on the ingredients list. I make my decisions based on how my hair feels instead of just focusing on different ingredients. No formula is bad and you really have to figure out depending on your hair.

Excellent video with Alexandra Arriaga. I need one video for the curly hair friends who are tired of hearing about the curly method and fear mongering against silicones and parabens. I have two questions, a) what ingredients should I look up for a heat protectant products and, 2) does deep conditioners are actually different than just conditioners?

I would love a follow up video about hair conditioners and what ingredients do. Also, the issue of people using dry shampoo regularly instead of washing their hair. IMO this practice is the equivalent of using a makeup wipe instead of properly washing face. Ok in a pinch but not for daily use.

I wish she would've asked about chelating shampoo ingredients and how they remove hard water buildup.

I liked this video a lot! It's a bit frustrating for people who are into haircare to hear that whether a product is good or bad for them comes down to unique user experience, because we all want clear easy rules we can follow, but the reality is that it's too complex to make large general recommendations like "no sulfates". The only thing I didn't like is the chemist seemed to be advocating a lot for just believing in the claims on the bottle because "in a world where everyone is ethical" but unfortunately, I don't feel like we live in that world. I believe the formulation chemists are ethical, but I don't necessarily believe all the marketing is transparent. For example: A product may be formulated to be a leave in conditioner but also contains an ingredient that is only mildly effective for heat protection in a low concentration. On the label, that nuance is lost though and just becomes "a leave in conditioner AND heat protectant!". That said, I guess that's why it comes down to user experience in the end. Unless every product comes with a detailed explanation of the intended goals when formulated, the consumer will never know until they try it.

I love this. Please have her on again. That was very informative. I’m so glad she dispelled all the fear mongering about ingredients that takes place on social media sites. ❤️

We need a sunscreen version of this!! So much controversy about chemical filters specifically!

Yes! I love this type of content. Fear mongering ingredients drives me nuts and I’m not a chemist! With regard to hair loss, I found eating more fruits and veggies seemed to stop my hair loss.

We need MORE videos like this! So tired of fear mongering around the hair and beauty community ❤❤❤❤

Awesome video! About the formaldehyde topic, there are some keratin treatments that claim to be Formaldehyde free and use glyoxylic acid, than what are your thoughts about this statement “Glyoxylic acid both releases formaldehyde when heated and is converted into either glycine by AGT1 (alanine:glyoxylate aminotransferase 1) or oxalate by glycolate oxidase in the human cell peroxisomes [4]. Formaldehyde is a colorless aldehyde poisonous gas at room temperature [5].Jul 11, 2022

Yesss! I love this type of education. We need more of this. Also, I love the puppy noises and interruption going on in this. We need more puppy attention in your videos, Abbey!

Hi Abbey, I really enjoyed this video, it answered a lot of questions. Thank you for having her on.

This was such a great video!! Please do another one with her! So much knowledge and information.

Super impressed with this sensible science vlog. Personally I do change my shampoos through rotation but it's certainly reassuring to know these chemists are ahead of the game 🎯

I use a clarifying shampoo once a month, however I wash my hair 2x a week and always do 2 shampoos with a gentle shampoo, so hopefully that’s enough

This was so good, I love Alexandra! Thanks for a great Q & A 🙏💞

I love this and so appreciate the time of both of you very knowledgeable ladies. My issue is I am overwhelmed with where to start to find what I need. So Abby your content of trying stuff and telling us your thoughts helps me narrow down. Even though my hair is much shorter and drier (older) than yours. Thanks again!

You little ray of sunshine! So happy when your videos come up!

I love Alexandra! Such a great duo!

“I go where the science takes me.” 🙌🏼🙌🏼🙌🏼 Obsessed. More interviews with chemists pls 😍😍😍 And now a new follower of Alex!!

Such a helpful video with great information, thank you!

I loved that video! It was very informative and cleared up a lot of things I was thinking about haircare! Also Abbey your dog is SO CUTE!🥰

The fact that my hair is gotten healthy because these two women and now they’re doing a video together is mind blowing 🥹✨✨✨✨✨✨✨✨✨✨

GOD BLESS BOTH OF YOU 🩵🩵🩵 knowledge is power- especially in the age of fear mongering around ingredients- I rely on experts like her and amazing influencers like you to break through the noise and keep me properly informed ❤ love you so much!!!! 💗💗💗 Part 2.. 3 and 4? Would love to have had a video surrounding ALL haircare- not just shampoo? 🙏🏻

I tend to trust the women in my community with my afro hair texture and their life experience with their hair because to her point regarding chemists knowing better from testing, afro-textured hair is underrepresented and we are expected to follow what is known about euro-textured hair for example what she said about co-washing, co-washing typically works well for many people with afro-textured hair.

so glad you did this collab!

This was aoooo informative, WOW! Amazing. I look forward to more chitchat between two ladies.!!’

Super excited for this video!!!

Yesssss been looking forward to this!😃

Love this!! So informative ❤ Once again, thank you 😊

She was so informative. Loved it!

I don't know how many European viewers are here, but wanted to leave this message from a simple laymen - user of beauty products: I have just discovered that Pantene has come out with an official bond repair line (it has bond-repair written on the label), and so far I can speak for the shampoo, it smells great - not too strong though, hair is soft and manageable ( I have wavy 3A-2B hair). I am so glad I have found your channel, I am slowly transitioning back to being able to buy drugstore products ( healing from buying "special brands" online only) - thank you so much for making scientific videos, I trust science and this makes me trust you :)

I have learned so much from two chemists on The Beauty Brains podcast. Valerie and Perry. They cover hair and cosmetics. They have saved me so much money. Love this kind of content.

So formaldehyde is bad but what about formaldehyde releasing ingredients such as Imidazolidinyl urea, and Diazolidinyl urea? Should hair products with these ingredients be avoided as well?

I appreciate you bringing on an expert. Seems like most answers were “it depends” but generally informative.

I really loved this video, it was so informative and useful! I'm following your recommendations about hair care, hoping for being able to restore my damaged bleached blond hair.

We need someone who addresses aging ( over 50) hair, thinning hair loss snd hair breakage for us. Not all of us in our 50s have the same hair as these two ladies in their 20s or 30s.

I’m a lurker follower👀👀but want to say thank you for the effort that went into this video!! It’s so informative!

Alex, please take Abbey to try some arepas and cachapas! She will thank us later! LOL! Both are great separately but together was EPIC!!! So happy with this collaboration!❤

What an awesome video, thank you both!

I cannot believe you guys collaborated 😱🇻🇪 love both of your guys’ content. Loved every about this collab!

1st I absolutely LOVE your channel and I just came across this video and OMG man I needed this video so bad and it helped me so much. Ive been looking for just a "regular shampoo" for just a once a week wash and on my other wash day im using K18 and now I have just came across Redken acidic color gloss and I really liked it but I've only used it once. I want some really good shine. Im in peri-menopause and my hair has just changed and just want some moisture and shine!!! Thank you Abbey for this and all your videos!! You are doing everything AMAZING and you look beautiful doing it sister!!!!!!!

Love this vid!!

I don’t know if I’ll make sense… but. All this great information does it apply to all hair textures? How do I know it’ll benefit me if I have very different hair than you two girls? Is anyone doing research for people with kinky hair? Or that all falls under the same category?

that was soo interesting! love this kinds of videos!

Great video, informative and fun.

This was a super helpful video, thanks so much! I was hoping she’d talk about shampoos that don’t strip color-treated hair. I tend to get brassy easily and my color tends to fade quickly. I’m getting it colored again this weekend and I want to preserve the $$$ baylayage for as long as possible.

Amazing this video!!! I neeeed to know how you darkened your hair! Love this colour on you!

Please do a review of the Loreal Metal Detox line. I trust your content and viewpoint!

Your dog is getting so big! What a cutie!

Hi Abbey, This was such an informative and helpful video to watch 💕.

Great video, so informative and I hope a lot of people see this, so they will better understand the chemistry behind this topic 😀❤️

Fantastic video, so informative, well done 🎉

Loved it!

That was so interesting! Have not been using olaplex much anymore and been using the redken acidic bonding shampoo and conditioner and I was just thinking like how could it possibly be bond repairing so her explanation was so interesting

Please Do a Review about Gisou hair products! I don’t think I see a video from you about their line yet. But maybe I missed it. 🙏🏽

I’m laughing so hard listening to Elsie going nuts with paper in the background 😂😭

Great informative video, thank you ❤

I thought 30 minutes was going to be too long to watch, but once I started watching, there was so much great content! Very cool video, it really cemented some ideas for me and ditched a few others. I'm gonna keep my high citric acid shampoo (at least, it's high on the ingredient list, but who knows what the percentage is lol).

Regarding “shampoo or cleansing cycling”, like skin care, I find that I do change my products seasonally. I have been growing my hair out for quite some time and it is now below my collarbone. I started using Ouai, because I needed to use multiple products on my hair. I cleanse every 10 to 12 days. I only use Ouai on my scalp and then Maui Shea butter on the rest of my hair. Abbe, I cannot thank you enough for all the tips, tricks and advice you give us. ❤❤ FYI, I now cannot apply mascara without blinking with each swipe 😘😘😘

Hi! Thanks for the video and the expertise. I am tempted to add mine, if I may, as a pharmacist. I think in theory there can be ingredients in shampoos that can promote hairgrowth! Although I think it is debated if the small time that the shampoo is in contact with the scalp can make a difference. I am thinking of products similar then minoxidil (and i think even rosmary), i.e. products that stimulate the blood vessels in the scalp. The reasoning is that if there goes more blood to the follicles, it grows faster. Minoxidil is scientifically proven (it was a side effect of another purpose it was used for). Anyway, but i wouldn't apply it via shampoo but more as a serum to have a better take up. Keep up the good work girls!

Great collaboration! Thank you.

Great Video. I actually watched the whole thing!

Abbey and Alexandria?! I follow both of you on Instagram and tiktok and I loved this collaboration video, it's definitely just what I needed today 💖💖

This is really interesting! I know a lot about skin and skincare but when it comes to hair I feel like I know nothing, so it's great to get all the info via your videos :)

Love this video! Love your content! Just wanted to pop on to say that an option to keep your pup occupied while you film could be some sort of enrichment activity! Like a frozen kong, but also she is always welcomed to be in your vudeos!

Great interview, common sense! Backed by chemist’s knowledge.. alternate non sulfate with gentle cleaners shampoos, not necessarily $$$ .. good stuff at drugstore and old school salon products likel Paul Mitchell nexus etc social media isn’t all true.. beauty industry isn’t regulated so they can claim all kinds of stuff..use what makes your hair feel good TO YOU.. wash hair enough to keep scalp clean 😊

Love the video but gotta say Elsie has gotten so big! So cute!

Part 2 please. Even more. 🙂

I would really love to hear your professional opinion on vegamor or Monat. I hear SO many mixed and biased opinions, but don’t know if they’re actually good or not! Love you

5:36 .... best part of video! "The dose is the poison". We all need to digest that.

Awesome video! I do have a random question that might be very ignorant. Do guys (or girls) with very short hair use conditioner to counteract that charge?

I disagree with the parabens conversation. I didn't pay attention to this sensitive ingredient until I found at 27 years old, I developed an allergy to them. My skin was wrecked, and had to work with a derm to fix it. I learned that excess use of sensitive ingredients over a long time can often develop allergies to it. That it's fairly common for this to happen. I recommend younger people to continue to be wary to reduce their chances of developing allergies to generalized sensitive ingredients. Itchy skin allergies are no fun, esp when it's unexpected :/

This was such a great video. I have only been following for about a month and im binging all the information. My fave part is the dose makes the poison and the remedy. Brilliant. I use all affordable drugstore products. My hair is doing great i think. I just stick with what works for me rather than worrying about prices. I just started a channel to promote hair health and appreciation and just taking the time to listen to our hair needs. 😊❤😊❤

I knew ingredients in Shampoos were safe, I use Old spice shampoo, has Sulfates and Silicones. Been using those for a long time, hair looks great, no build up. Just can't listen to those people demonizing certain ingredients! Very informative video here😉

Great video!

As a curly hair black woman, I see so many vdeos of KZfaqrs slathering so much product on their hair. I haven't been doing that because where I live haircare products are costly. But with my hair type it's been working for me to not slather so much product.

Definitely agree on cycling shampoo though. I use different shampoos during different times of the week depending on how my scalp feels. If my scalp is flaring due to my eczema, I will use my shampoo for eczema. If it feels slightly irritated, my redken Zinc shampoo. Ill clarify if it feels like I have some buildup. But not often because itll irritate my dry scalp. Ill use my "detox shampoo" when my scalp feels fine. Whereas my "moisture" shampoo ill use when it's slightly dry. It depends on my scalp climate 😂

Thank you for this video! I feel a relief now that I don't need to stand in an aisle for 30 minutes reading labels and freaking out because of all the false info out there.

Great video Abby❤️🇨🇦

Good job!❤

Id be curious about how does protein affect the hair? I see people talk about protein overload. But we need to know whats right. Lol. Basically protein overload vs moisture. And moisture overload too 😂

Are proteins something to avoid for fine/thin hair? Rumor is that proteins are bad for “low porosity” or finer hair types and can cause ends to become dry/break off. Would love to know your thoughts on this!!🩷

Lots of "it depends." What are examples of mild surfactants vs stronger ones (so we know what to look for on labels)? Same question with silicones. Also, it seems this information is mostly applied to straight hair. For example, curly/wavy hair won't be able to curl as easily if heavy silicones are coating hair (bc water can't get in - which is needed for curl). Lastly, it's important to consider the environment with the products we use. Parabens have shown potential to bioaccumulate. I prefer to avoid so as not to contribute to the problem. There are SO many good products without them.

Great interview! I have curly hair and wash my hair every 5-7 days, my scalp isn’t oily. Is it okay to was infrequently?

Can a detangling/conditioning spray act as a conditioner or do you also need an in shower conditioner? Sometimes I just dont feel like taking the extra min in the shower for conditioner and do the spray one after.

Love all your videos!!❤ And i was wondering since you’re a trichologist in training I would like too know your thoughts on nioxin shampoo or Rogaine? Have you tried those product?

i love how you take haircare so seriously, the way you use scientific approach is just 👌

PLEASE MAKE A VIDEO OF LOREAL PRO LONGER HAIR MASK, there's not a lot of info bout that products on KZfaq. And I'm a bleached blonde asian who needs helpppp

Great video ❤

This and another video hinted at a possible hair care launch… do it!!!

thank you I learned alot and understood!!!

The best shampoo I've ever used had a silicone high in the list. My hair is easily dried the hell out simply by cleansing, no matter what the shampoo

19:29 I'm pretty sure the biggest cause of hair loss is androgenetic alopecia which you cannot help with any shampoo, except maybe Nizoral to some degree because it has some anti-androgen properties.

There was no questions about dry shampoo. Many people say it causes hairloss , there were even recalls on some dry shamppos. Would of been intresting what she would of recommended.
