Verdict —Not a conditioner, not a mask — a repair treatment that genuinely rebuilds damaged hair.
I've been double-processing my hair since I was 22. Olaplex No. 3 is the reason I still have hair to write about at 29.
This is a pre-shampoo treatment, not a mask. You apply it to damp (not soaking) hair, work it through mid-lengths and ends, and leave it for 10 minutes to overnight. Then shampoo and condition normally. The first time I used it I noticed less breakage on my brush by the third wash.
One bottle lasts me about four months with weekly use. Non-negotiable in my routine — especially the week after a color appointment.
Pros
- +Visibly less breakage after 3 uses
- +Cuts my mid-lengths' brittleness in half
- +Safe to use weekly on colored hair
Cons
- –Needs at least 10 minutes to work
- –Won't fix damage on its own — pair with a good conditioner
