  • Love it!

    Posted by Tabetha on Purebeauty

    I bought the 3 part system and love it! You can most definitely see a big difference after 1 use. I wish I was told about this product years ago. I do recommend the pumps for the shampoo and conditioner bottles, also you only need a small amount it's very concentrated.

  • It's shampoo

    Posted by Sylvana on Purebeauty

    It worked the first two times i used it. My hair looked great. Now it makes my hair an oily mess really and my hair is dry at the ends but oil at the root after using this. The shampoo dries my hair out like crazy.

  • Bonus a little goes a long way!

    Posted by Marianne T. on Purebeauty

    Best shampoo ever. Helps hair feel super soft and brush runs right though it easily, even if working with damage. Tip- a little will do it. I have medium length hair and it is moderately thick. I used a quarter size amount. Dabbed it throughout hair about six different areas then put the rest on ends and it lathers up great!

  • Took it after the gastric sleeve

    Posted by KelliW on Purebeauty

    The smell to me is similar to dish soap..however the product itself is amazing. I had the gastric sleeve a year ago and have had extensions in for months due to embarrassment of thin straw like hair. For the first time in no the I have no extensions in and my hair is shiny. I can actually brush it and it doesn't stick straight up. The picture to the rt is after 1 deep treatment and 2 washes with the shampoo and conditioner
