I received two samples of this and I'm now purchasing the full size as it really did help out my hair so much! I have oily roots and my mid length is damaged, and I struggle with frizzy dry ends. I used both samples in-between seeing my hair stylist and she said my hair is much healthier and I didn't even need a trim, which is perfect because I'm trying to grow it out! Easy to apply before washin...
I never felt any difference in my hair with Olaplex 3 so I tried this on the advice of my hairdresser. Wow, what a game changer! I used it once a week for a month, then bleached some of my already very damaged hair - not a single bit of breakage! I'm going to continue using this one.
