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.
