I have been using this product for over 6 months and my hair has never been thicker or longer.

I completely get why this is an award winning shampoo. It does great things for my hair!

i use this shampoo and the 4c version and i love them both. a small amount goes a really long way which makes up for how small the bottle is for the price. i have fine and oily hair which was always frizzy. this shampoo makes my hair smooth and it feels noticeably cleaner. i dont think i’ll ever go back to basic shampoo again because any time i do my hair feels dirty, heavy, and frizzy.

Really love this shampoo. Really helps with my damaged hair!

I like both Olaplex shampoo and conditioner. This is my second repurchase. Out of all shampoos I tried, this is one of the good ones. It leathers very well. Smells good. It doesn’t do wonders to my hair but I would still buy it again.
