Rated 5 out of 5 by from Excellent for colour treated hair My hair has been bleached and coloured about 10 times in the past six months, so the ends of my hair feel like straw. I've tried lots of different deep conditioners, treatments, etc. but this is the only thing that has made the ends feel like normal hair again. I spray some on my hair after towel drying, work it through, and then use my other regular styling products.

Rated 5 out of 5 by from "The most attractive hair is clean, good condition hair." I left my hair color in too long. Hair dry and brittle. I first used the The One n' Only Olive Oil for dry hair shampoo, then the Ion deep conditioner. BUT...I finished it off with this, One n' Only Brazilian Tech Leave-In conditioner. My hair is soft, curl is still there and looks shiny and conditioned. The quote I put at the top, I can't remember where I read it. But after observing women with beautiful hair colors, but their locks were dry and didn't have that nice conditioned healthy shine, I realized mine probably looks that way also. I was doing well until I over-processed last time. But after using the above steps, my hair looks healthy and natural and you would never know I color my hair.

Rated 5 out of 5 by from So Far So Good First, I'll state that my hair is fried and have been nursing it back to health. I previously had the It's a 10 plus Keratin leave-in and I enjoyed it a lot. I recently ran out and after reading reviews, I picked up Brazilian Tech. I've only used it about 3 or 4 times, but I'm completely in love with it. My hair is thin naturally and curly. This stuff not only helps detangles, but it truly deposits the keratin where you need it the most. My hair has been so soft, manageable, and extremely shiny!! It looks and feels sooo healthy. I would definitely recommend to anyone! Also, yesterday I straightened without any heat protectant because this is suppose to help protect too, and the results were completely amazing!

Rated 4 out of 5 by from This product smells wonderful and detangles well. It left my hair soft and manageable. However, while my hair is damp from a wash and a few spritz of this stuff, my hair felt kind of sticky and filmy. This stickiness would only go away when my hair is completely dry. I don't like to apply too much heat on my hair but with this product, I would have to blow dry my hair right away to avoid that sticky feeling. This is why I was not fully satisfied with this product and went back to using Miracle 7 with keratin.

Rated 5 out of 5 by from One'N'Only Keratin Leave In I really love this product! If you like "It's A 10" leave in, wait until you try this. This is a lot better. Makes your hair smooth and soft and no frizz, and doesn't leave that filmy feeling on your hair as "It's A 10" did with mine. It also smells nice. I suggest spraying it into your palms and running it through your hair, and don't be afraid to use a lot. I tried spraying it on and combing it through but didn't feel the full results.

Rated 5 out of 5 by from GREAT PURCHASE I tried this product for the first time and I love it I don't really try new things unless It's been around for a long while i read the reviews and I went out and got it I crossed my fingers and I love it

Rated 5 out of 5 by from does what it says I used Miracle 7 for about a year and while it was good, it is no where near as good as this One and Only Brazilian Keratin treatment. I have curly hair so I blow dry it and then use a hot iron to get it straight which of course has left me with damage frizzy hair but with this product, you would never know it. My hair is shiny and so soft that I find myself running my fingers through my hair all the time. My hair looks better each time I use this product and I will never be without it!

Hi! Do you need to use a hair straightener to apply this product? Also, how long does It last and is it safe for color treated hair? Thanks! Laurie

Asked by: laurie01
My hair is very curly, not course, but curly and I'm afraid of straighteners which is why I love this product. It keeps my hair from getting frizzy during the very humid days when I insist upon blow drying my hair. I really love this product. It's very light; doesn't make my hair greasy.

Will the Keratin one 'n only Brazilian Tech Leave-in Treatment work well if you have never used the keratin smoothing system in conjunction with it?

Asked by: Bre
I haven't used any other keratin system, only this leave-in treatment, and it makes my overly-processed hair feel really soft and smooth. It's the only thing I've tried that actually works to get rid of that dried out, crunchy feeling that my bleached, colour-treated hair has on the ends.
