Wow product

This is the best product I have ever bought to give my hair a sleekness and softness. The frizz and dry hair is gone. I’ve bought the shampoo and conditioner. Can’t wait to try it when it arrives. I’m impressed by this product. It really does what it states it will do.

Hair needed help.

I have used this for a few weeks. My hair does seem to be softer at the ends. (Color treated hair) I will continue to use it. Sam's price was less, as well.

Nice stuff

Very good project, you use in place of conditioner when you get out of the shower. Use about three times and your dry, damaged hair will feel like new. They recommend to use 6 times to finish the course. Really nice product. Will buy again.

My holy grail of hair repair

After I fried my hair by dying it myself (then trying to correct the messed up dye job several times, stripping the hair completely), I had to have a hairdresser correct it. She begged me to cut off my long hair due to the damage. After I came across the recommendation for K18, I tried it, and right after the first application, my hair was already much silkier. After 4 applications, as promised, my hair was nearly as healthy as it was before the chemical stripping disaster. I, then, bought K18 for my daughter who has naturally wiry hair. She was skeptical and didn't try it right away. Eventually, she ran out of her own conditioner and turned to her bottle of K18. She's been hooked on it ever since. This product is as good as they say it is, and despite its high cost (it is VERY pricey), it's worth its weight in gold if you have damaged hair.

K18 is the best

This stuff is the best to use on bleached hair. I bought so many of these bc the price at Sam’s was cheaper. I hope they continue to sell this size!

Was so excited to find the K18 at Sam's Club for an amazing price. This is my 3rd time purchasing K18 for my hair. Definitely recommend.

Not the damaged hair cure I was hoping for.

Not as moisturizing as I'd hoped. I'm in my 50's, and my hair is dry, coarse, curly, thinning, chemically treated, but also needs a cut badly. I returned it.
