Overview
Lathering this Olaplex clarifier into wet hair once a week lifts away chlorine, heavy metals, hard water minerals, oil and product buildup. The pH-tuned, sulfate-free formula cleans deep without stripping color.
Clearing buildup that dulls hair and blocks repair products is what it does well, and it is safe on colored hair. As a weekly clarifier, you still need a regular shampoo for other wash days.
Who it's for
People who swim, live with hard water or use lots of styling products will see brighter, softer hair. Those who wash daily with few products may not need a clarifier.
Pros and cons
- Removes chlorine and minerals
- Sulfate free, color safe
- All hair types and textures
- Boosts repair routines
- Weekly use, not daily
- Needs a separate everyday shampoo
- Strong cleanse can feel drying
Performance notes
Cleansing power comes from a pH that lifts the cuticle so trapped minerals and residue rinse out. Emulsifying in the hands first spreads it evenly, and a thorough rinse prevents leftover film.
