GK Hair Taming System for Frizzy Hair, Smoothing, Moisturizing, Straightening - 10.1 oz Treatment

This product worked for me! I followed the very tiny printed directions on the back of the product tube and my hair feels sleeker and took much less time to dry! I highly recommend it. I do suggest that an instruction sheet be added to the box with larger type instructions for this of us older than age 35! Thanks!

It really works! I have dark, thick, wavy hair, currently with blonde highlights. My brazilian wore off months ago and was having trouble with my rebellious long freezy bangs. I followed the instructions, used the GK shampoo, conditioner and serum drops, and my hair is just super smooth and tameable now! I dont even have to blowdry/iron it. Will buy again when i run out of it!

I found this product pretty easy to use, with fantastic results. My natural hair is about 60% grey, fairly fine, wavy with some frizz and a bit wiry. It eliminated about 2/3 of my hair's frizziness, left it noticeably smoother and faster to blow dry, without leaving it totally limp or lacking any volume, as some previous salon keratin treatments have done. It has been about two months since the treatment, and the results are still noticeable, although the areas around my ears and nape of neck are starting to revert to some frizz. I am not noticing any damage or breakage. I have to say this is the only thing I've ever used that has made my hair really manageable since I started going grey. Its normal state is very dry, brittle and wiry, and this left it smooth and not requiring much styling products. I have not tried air drying it, so I don't know what it would do without any styling, but with a little leave-in conditioner and brushing it against the curve of my skull, it comes out just the way I like it. I am totally thrilled with this product and will be using it again. The small bottle will probably yield 2 or 3 treatments on my shoulder-length hair.

I love this product. I have given treatments to several friends, as well. It is botox for the hair. Makes coarse hair soft, thin hair thicker, cuts drying time, smooths frizz. AMAZING.

Product in tube and shipped in brown paper bag, got squashed along the way and product not sealed. Extremely bad experience compared to other companies selling keratin products and for the price one would expect proper care of product during transit etc. and also product should be sealed to ensure no tampering with it.

I used to get Brazilian Blowouts and loved them. I bought this thinking it'd work. NOPE! I did it twice. The first time according to the teeny tiny instructions on the bottle (which doesn't look like the one in this picture). Waited 3 days to wash it. Hair was just as frizzy and curly as usual. Then I looked on YouTube and did the "italian method". Again, waited 3 days to wash it so it would "set". Just as frizzy and curly as usual. The only thing this DID do is make me $50 poorer. Run... don't walk... away from this useless product.

I used the product and followed the instructions exactly, TWICE. My curly hair is exactly the same and doesn't even feel softer. It looks nice when you straighten it to finish the process but once you wash your hair it reverts back to how it was. Super disappointing.

When applied blow dryer and use the flat iron look good I waited one week to wash and there was the final results my hair look very unhealthy very dry I am not happy.

I order GK HAIR Global Keratin The Best (100ml/3.4 Fl Oz) Smoothing Keratin Hair Treatment - Professional Brazilian Complex Blowout Straightening For Silky Smooth

My hair is naturally hideous curly/frizzy, not cute curls, but with a good keratin treatment I can make it look fab. However, it DOES need to be pro-strength. Global keratin used to be so fantastic but for some reason they changed the formula and it's gotten so weak. Go back to the old way, Global! If anyone out there is having this same problem, Uncurly works as well as the old Global, maybe even better. But this Juvexin stuff is very disappointing -- weak effects, short-lived.
