Paul Miller –
After using Olaplex No.0 followed by No.1, my hair feels stronger and less frizzy. The damage from bleaching was noticeable, but after just one treatment cycle, it looked healthier and more manageable. I’d recommend this for anyone with damaged hair.
Brian Glover –
My curly hair had split ends and was very brittle. After using No.0 and No.1, the hair became smoother and less prone to breakage. The treatment is easy to apply and works well even on thick hair.
Katherine Marshall –
I’ve used this treatment twice now and see a noticeable improvement in hair strength. It doesn’t smell strong, and the application is simple. Still, I wish it worked faster for severely damaged hair.
Andrew Brown –
This is the first time I’ve seen a hair treatment that actually repairs rather than just mask damage. My hair feels more resilient and looks shinier after just one use with No.1.
Evan Rampling –
The results are good, especially for someone with heat-damaged hair. I apply it once a month and notice less frizz and better hold. It’s a bit pricey, but worth it for the quality of repair.
