  • Best shampoo!
The shampoo! Being 60+ starting to have some thinning hair also, I like, used to do keratin treatments. But because my hair is thinning have stopped, and the shampoo gives me silky, soft and much thicker results.

  • Worth the investment
I've tried a few shampoos that claim to repair and add strength to the hair. None of them compare to this product. Sure, you can buy something cheaper that promises repair and strength, or you can spend a little more and buy this product that actually works.

  • Fresh smelling, tangle removing shampoo
It smells good, citrusy, clean smelling shampoo. It makes my hair lighter and smoother, tangle free

  • Pump action is so worth it
I love what Olaplex 4 and 5 do for my hair. I was buying the normal size over and over and didn’t like that I had to store the bottle upside down to use everyday. This larger size is more cost effective and I get the perfect amount each time with the pump and can actually store it right side up! And no mess. Because I use less now (since I can better control the amount) I think it lasts even longer! ... show more

  • Great Product but Missing Pump... Twice!
The product is truly a game-changer; I can't wait to wash and condition my hair! My hair is soft to the touch and so smooth. I bought the No. 4, No. 5, No. 6, No. 8 and the Oil. All products have exceeded my expectations. But my first order of Shampoo No. 4 arrived without a pump top. Replacement bottle also arrived without a pump top. So, now I'm buying $6 universal pumps on Amazon because it will cost me more in gas to make the returns and risk that the next bottle is missing the pump top too. This review is really for Amazon & Olaplex purposes so they can solve the mysterious missing pump top problem (and, no, they didn't fall off inside the shipping box.) Also, it only occurred on the bottle of shampoo, not on the bottle of conditioner if that helps to know. ... show more

  • Amazingly good
Makes my hair feel soft. A little goes along way. Smells delish. A little high in price but I’m trying to determine with continued use if my hair will improve.

  • Can't go without
Olaplex has strengthened my hair so much over the last year. I love all the products.
