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)

This is easy to use. I have short hair, so I know it would take longer to do yourself with long hair. This is a different product than the one you can't wash for 2 or 3 days. This is applied to the hair and rinsed out. Then you flat iron the hair. Your hair still has body but no frizz. I applied it about 3 or 4 weeks ago and it still has shine. I love it because I can just let it dry if I am not leaving the house and my hair still looks ok. I don't like to blow dry or use product in my hair if I'm staying at home. But it's easy to brush some water through and style it a little when I do go out.

Product came super fast! I was nervous because I have dark brown hair that I dye with a combo of 5AA and 6AA with 20 Volume Developer. Highlight a couple of times per year. Occasionally turn a little brassy. Based on another person's review, I used a very low heat setting (360) on my flat iron and I had zero color lift.Here is what I did: watched the vimeo video at this link:[...]. This is a MUST. Washed with Paul Mitchell Shampoo Three. Towel dried to about 70% dry. Sectioned it off into 4 sections. Shook the tube as best I could I put the product into the bowl. NOTE: Do not waste the product -- I did. I could have gotten away with using only 1.5 ounces and then I would have had enough to do this again later. Put the product into my hair in sections and carefully combed thru with a fine tooth comb. After my whole head was covered, I set a timer for 20 minutes. I also set another timer for 5 minutes. Every 5 minutes, combed thru all my hair from root to end. After 20 minutes, I rinsed it out in the shower for 4 minutes. Blew it dry 100%; flat ironed it at 360 in very small pieces. The result was amazing. Super straight and looks like a professional job. True test will be how it holds up in the hot and humid NJ weather.

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.

just used this for the first time. i wanted to decrease the frizziness of my hair without losing the body. when my hairdresser does keratin in the salon, she tends to flatiron it to oblivion and i don't like my hair for at least a few weeks until the body comes back. i figured i would try this at home and regulate the amount of straight i wanted to achieve. my husband helped me apply it as i was hesitant to attempt this for the first time by myself. this product has a slight smell and definitely burns when applied to areas where i had scratched or used retin a(forehead close to my scalp). followed instructions on the amazon webpage. i didn't want poker straight, no body hair so i only used the flatiron at 360 setting. my hair looks amazing and has so far the right amount texture and body. this is a great, easy to use product. follow up after my second treatment, it absolutely pulls color from hair esp the roots. i just did my hair for the second time and my jet black hair has reddish black tinge for about an inch from the scalp. i have to dye my hair every three weeks for gray, so i will have to wait a few days to get the color back. even with this issue, this product is still amazing. second time even better than the first.
