  • Works great!!!
Size: 3.4 Fl Oz (Pack of 4)
I’ve used this product twice now and about to do y 3rd treatment, for me it lasts about 5 months but I’m sticking to an every 6 mo. schedule and it really works great!! My hair is thick and naturally curly. I straighten my hair 99% of the time and tho this product doesn’t straighten my hair if that’s what you are expecting that’s not what makes it so great!! What it does do is it helps keep my hair frizz free in humidity and is a COMPLETE game changer!! I travel alot and when I get hot or in humid weather my straightend hair gets big and frizzy and the curls come back ima wired way lol but this product keeps my hair from doing any of that!!! It really tames my hair and keeps the frizz away!! After about 5months it is very noticeable the difference when it starts to wear off!! I am so Happy with this product. ... show more

  • Works on 4C Hair
Size: 9 Piece Set
This product works well on natural 4c hair. I was reluctant to try it, but I'm glad I did. It works way better on my hair versus the Design Essential STS treatment. Also, it's a fraction of the cost they charge in a salon for this type of treatment which runs a couple of hundred dollars. It smells nice, didn't irritate, or burn my scalp at all. My silk press came out just as good as a salon visit. It even lasted through some sweaty gym session with a sweat band of course too. It puffed a little at the roots, but my hair did not revert back. Once it was dry I was able to wrap it with a scarf tied down to lay it back down and/or use the flat iron for a little smoothing. And best of all I can apply this in the comfort of my own home. I definitely will be using this product from now on as a staple for manageability of my hair. Glad I gave it a chance. ... show more

  • NOT worth the money AND Terrible customer service!!
Size: 100 ML Kit
I followed the exact directions, step by step and even though my hair felt great right after the treatment, after the 1st wash (using the included shampoo+conditioner), my hair went back to almost the same texture as before. It was still frizzy and curly-ish. It had a slighter smoother texture, that’s all- DEFINITELY Not worth the money. Also the after-smell of the treatment is just awful! It’s so bad I have tried to get rid off it during the last few washes by using different shampoos/conditioners that smell good, but I can still smell it, especially when is wet. I would not recommend this - I would just go to a professional salon next time and pay the extra$ for a good product, labor, and the long time it takes to apply a keratin treatment. UPDATE: the company contacted me to ask me which steps I followed. I explained to them that I followed the exact steps listed in the instructions, EVERY SINGLE ONE. They messaged me another 2 times inquiring about the iron temperature I used, and other specific questions, to which I answered. then they emailed me again to tell me They don’t believe I followed the proper steps!! This is THE WORST CUSTOMER SERVICE I’ve ever had! If you are going to email your customers to ask if you followed their instructions (which I very carefully did) and then tell them you don’t believe them you shouldn’t even be in business! I 100% WASTED 100$ and also the ton time I spent applying the product AND answering their pointless messages. IF I COULD GIVE THEM NEGATIVE STARTS I WOULD!!! ... show more

  • Close The Cuticle
Size: 3.4 Fl Oz (Pack of 4)
We hoped to achieve a longer term smoother look. This product gave a shiny appearance and tamed the cuticle but probably won’t buy again as our hair is too curly. Easy to apply and smells good. Product probably best for hair which is not super curly.

  • The brush it says to use to apply the step 2 product was not in the box
Size: 3.4 Fl Oz (Pack of 4)
This is my second time using the product. The first time it actually lasted about 8 months and I was shocked it even worked at all, not to mention how well it worked. Just got the second box though and the application brush is missing. Very inconvenient considering the price

  • It worked!
Size: 3.4 Fl Oz (Pack of 4)
The media could not be loaded. I been looking at this for like a year. From the reviews I was afraid it wouldnt work. This is the same brand they use in the salon when I get it done for $200. I didn't think it could give me the same results so I decided to get the salon treatment again 3 months ago. I didn't use the GK hair products to maintain it this time (the salon raved about another product which sucked) as a result my treatment didn't last at all. This time I decided to give this a try but I was really skeptical. My hair is super thick and coarse and frizzy. Did this treatment according to the instructions on the box, it turned out just like the salon. Now the true test will be how it holds up after washing. I will update..... Update: its been almost 2 months and my hair is still frizz free. I did buy the deep conditioner packets and use it once per week. I hope they never stop selling this! ... show more
