    Great product but bottle was leaking upon arrival. That would be my only concern

    Made my hair very soft and manageable. It also enhanced my color.

  • Journey back to healthy hair

    Posted by Marcia Moore Travis on Purebeauty

    I've been using Olaplex No 3, at home hair treatment, with the advice of the owner of the Aveda Salon I go to since October. Prior to that, my hair was over-processed (former salon), lifeless, damaged, dry, brittle, and looked like it was losing its fullness. The Olaplex completely turned the condition of my hair around. So adding in the No. 4 Bond Maintenance Shampoo, as well as the No. 5 Conditioner has made my hair strong, shiny, and healthy. I've bought Olaplex for my nieces and would recommend it for anyone struggling with damaged hair, especially from being over-processed like mine was.

  • My holy grail of hair products

    Posted by Aimee P on Purebeauty

    Let me start out by saying I have naturally curly/wavy hair - think low-po, coarse, thick 2B/3C hair. I have tried so many brands over the years, but I struggle with frizz a lot even when it is moisturized and healthy. (I live in a really humid place.) I switch between wearing it curly for long periods or also blow dry and curl. I was really reticent to spend the money on the shampoo and conditioner set, but I'm so glad I did. My hair has never been silkier, smoother, or healthier! This pic is even right after a color/foil treatment, and you can see how healthy it still is. Plus, the product is so incredibly concentrated, it takes very little to use it (and I have mid-to-long length hair). In fact, I just reordered the shampoo after using the same 8oz bottle for nearly 6 months. I now use this line almost exclusively. I love the No. 6, as well, because it is great as a styling cream wet or helping touch up dry ends between washes. Please, please, consider investing in this. You'll be surprised how long it lasts and your hair will thank you!
