Olaplex No. 3 Hair Perfector, 100 ml
Our verdict
Bleach, heat, regret — No. 3 repairs the actual broken bonds, not just the appearance of damage. The one treatment that made our hair feel structurally different after one use.
- Bond-building tech
- Pre-shampoo, 10-minute treatment
- Works on all hair types
- Salon-proven, 3-month supply
Why we picked it
Apply to damp hair, wait ten minutes, wash out. Sounds too boring to work until you run your fingers through your hair that night and it is... smooth? Week by week, the porosity calm-down compounds: less breakage in the brush, shine that is not from silicone.
It is a pre-shampoo treatment, which confuses everyone once — then it becomes the ten-minute ritual you protect. One 100 mL bottle covers about three months of weekly treatments on medium hair.
Best for
- Bleached, coloured or heat-damaged hair
- Pre-wedding or post-summer repair
- Anyone whose hair feels like straw
Keep in mind
- Ten minutes minimum; more is fine, more product is not.
- It is a treatment, not a conditioner — follow with your usual mask if needed.
