PETER COPPOLA a-Keratin Smoothing And Refinishing Treatment - Semi-Permanent Keratin Hair Treatment Smoothes, Nourishes, And Repairs the Hair - Formaldehyde-Free, Aldehyde-Free (3 Ounce)

I absolutely love this treatment! I've tried several others, but I get the best results with Peter Coppola. One thing to keep in mind is that it does lighten your hair; it lightens mine, but I always end up loving the results.My hair remains straight and frizz-free for quite a while, and it feels soft and smooth. I couldn't be happier with it!

My original review: Important to note that this product is different from coppola keratin complex which I have used for the past 10+ years. This Peter Coppola A-Keratin treatment does not contain formaldehyde and all the awful chemicals. I have always had great at home keratin treatments in the past using the strong noxious fumes version, so I was excited to try this all natural chemical free version and hoping it would work just as well. The steps are basically the same except you rinse the product out then blow dry and flat iron. Also no waiting 3 days with the product in your hair looking like a wet rat, which is nice. This product went on easily and while I had my doubts - Im very happy with the results so far! My hair is a single process bleach blonde for the last 5+ years and I just had extensions taken out so my hair was thin and extremely damaged. My natural hair is kinky curly like ramen soup and all frizz - totally impossible to style. Thats why I have religiously done keratin treatments every 6 months to keep it straight. I think the before and after photo speak for themselves - This product does what it promises and without the harsh and harmful fumes and chemicals. I will update if anything changes or if it doesn’t last as ling as expected. A few tips - follow the directions exactly, I used the PC clarifying shampoo before and set a timer on my watch to comb thru every 5 mins while the product was on. I left it on for 45 mins for my hair type, and when they ends would dry out i would add a but more product to the ends so I could keep combing every 5 mins.Updated 1 week after application. Well, my hopes and dreams have been shattered with this product. After 2 washes and one week post application, my hair still air-dries totally curly just like in my before picture. Unfortunately it is not as strong of a treatment as the original keratin complex (with all the formaldehyde and chemicals) I really wanted a safer more natural solution to getting my hair to air dry straight, but this product just doesnt cut it. Sad, bcs I really thought it would work, sadly it just doesnt live up to the straightening power of the real keratin.

First, this stuff works great my hair was pin straight even in humidity and I have naturally curly hair. It was pretty easy to put on too. So why the one star? After 2 shampoos i noticed an odd smell and I wasn't sure where it was coming from. I changed my pillow, changed shampoo, changed conditioner and the smell got worse. I realized it was this product. With every shampoo your hair smells worse. Cats follow me now when I go for a walk thinking I am wearing their litter box on my head. Vultures circle and my dog vomited last night when i went to pet him goodnight. I am trapped, I want this demon crap out of my hair but I am afraid to wash it one more time! I cant imagine what the next shampoo will uncover. It is like those layered scented candles only this one is scent of: day old shrimp, multi cat litter box, old wet pennys.....too afraid to shower!

Update after 2nd time:So the first time I did this treatment I was really nervous and used a very low heat setting on the iron. Needless to say it didn’t work. I had half a tube left of the formula so I did the treatment again a month ago, 5 months after the first time. Results are much better.I coated hair more thoroughly and used a higher heat setting while ironing. I haven’t lost volume but my hair is 90% frizz free and my unruly curly hair is now beautiful gentle waves if I let it air dry. If I blow dry then it takes me half the time and my hair looks amazing. I will definitely keep using as I want a gentle formaldehyde free product. Also my hair looks much healthier and has great shine!Original review: I have done keratin treatments at salons throughout the years but I wanted to try one at home. I was very skeptical reading some of the reviews but spent hours researching keratin treatments and decided to purchase this one. The process was very simple and from shampoo to done took me an hour and a half. I have very fine hair, down to my collar bone, which I color every 3 months and highlight every 6 months. My hair is super frizzy which is curly on the bottom and totally unruly in top. I have been blow drying my hair since I am 12 and absolutely cannot leave the house without styling it. Even so, after 30 minutes outside my hair frizzes, which is very frustrating.I was very careful in the application and used the solution very sparingly, using only half of the 3 oz bottle. I left it on for 20 minutes as my hair is very fine and processed. Due to my hair type I used a very low heat setting with the iron and ironed my hair in large batches as I was concerned about breakage. I colored and highlighted my hair one week ago and was also concerned from reviews that people said turned their hair orange. I am happy to report that my hair is exactly the same color as before the treatment.I just finished the treatment so will update in a week or so but so far it is amazing!!! Even while I was blow drying my hair (before straight ironing) I noticed that my hair was much straighter and frizz free.UPDATE after 2.5 weeks - So I was really hopeful this would be amazing. Unfortunately the results are just eh. I have about a 30% reduction in frizz and 40% reduction in curl. I must blow dry my hair in order for it to look good. It does shorten the styling process, but I was hoping for much better results. I read that sometimes the 2nd treatment works better. I will do so in about three months and post results... and yes, when hair is wet is smells like a wet rag but goes away after a couple of weeks.
