I have used GK in the past (salon) and loved it. The Best is even better, easy to apply. The sellers provided a how to brochure plus extra product samples to try. My package arrived quicker than expected. My hair feels awesome! I will order again.

I really liked the product. I have had it done by a professional in a salon and honestly was not happy with the results. I dont think the stylist used enough product or diluted because my hair came out when better I did it myself. I have naturally curly hair that air dries to a puff ball. I also have colored hair that I need to do regular root touch up for very resistant gray as well as blond highlights. I know a lot of "hair issues"! At any rate this product did exactly what it said it would do. The only reason I didn't give it five stars is because although I had really good ventilation, all windows open and ceiling fan on. It did give me a bad headache all day the next day. The smell was so bad that I had to rinse my hair and do a Conditioner rinse to try to get rid of the smell. That didn't work so I went ahead and washed it with the GK shampoo after 24hrs( instructions say wait 48hrs). I let my hair air dry and it dried to nice smooth free beach waves that did not puff! I would definetly recommend this product, but absolutely follow the directions and do not over apply the product. I only used half the bottle for shoulder length thick hair. When I ran the comb thru, I hardly had any excess build up in the comb, it you do, you've used too much! May the hair fairies be with you!

exactly as ordered, just what I needed, cheaper then at a salon. arrived early, thank you

“The Best” Keratin treatment is definitely the most amazing keratin treatment I have ever used! The application is so quick and easy. The product goes on the hair so nicely and spreads easily! So it cuts down on application time. You can also customize the treatment dependent on hair type and texture which is great because you can use it on all types of hair! The curl and frizz reduction is incredible! I’m so happy with this product and will continue to use it in my salon and replace the other Keratin treatments I previously used with The Best!!

I Usually don’t write reviews,but I have to say these product have work wonder for my hair.I live I. Florida now for the pass 4 years I have been trying out all kinds of treatments for my hair,it’s process blonde color,hair is very frizzy and has lost his shine and does not look smooth, but I thought trying these GK products my shine has come back my color of my smoothness on my hair I have used it twice, very happy with the results so will try it again in three months.
