This was recommended to me for my fine hair as both a heat protectant and styling serum.
I used it for the first time this morning and, so glad I listened. My hair is so shiny and soft. And, after using my L’ange duo to do waves in it, and I’m so happy with how much better they look!! I’ve received multiple compliments on my hair this morning at work, as well saying it looks so soft.

I’ve put off buying Olaplex products for years bc they’re so pricey. Recently got my hair highlighted & it felt super dry, so I splurged on myself for once & bought this. I could tell a difference after just using this product ONCE. Will definitely be buying from now on.

Love this product. I use this in place of conditioner and apply after my shower. It is great for crunching. Use less for a softer look or more fore that kind of wet look. It helps condition my hair and helps with straightening. Overall great product, no complaints.

I bleached my hair and went to cut the ends. I still have some hair remaining that was bleached so I really don’t want my ends to end up being so dry again. I’ve only used this twice and used one pump on my hair after towel drying it. And when I either air dry or blow dry it, it leaves my hair really soft and healthy. Love it!!
