OLAPLEX Weightless Nourishing Hair Mask for Fine to Medium Hair

Editor's Take

Olaplex gets the fine-hair brief right: credible bond repair and Polyimide-1 support without the usual butter-heavy drag, though the environmental bill is hard to ignore.

Four-pillar formula scores

• Performance: 8.2 / 10
• Innovative Ingredients: 8.5 / 10
• Clean Standards: 5.5 / 10
• Formula Sustainability: 4.1 / 10

The Verdict

The formula is unusually well judged for fine to medium hair, smoothing and sealing without turning the mask into a tub of heavy butter. Bis-Aminopropyl Diglycol Dimaleate supports bond repair, while Polyimide-1 helps preserve body and resist humidity. Amodimethicone and Dimethicone add useful polish but may build up, and the fragrance, quats, and persistent polymers weaken its clean and sustainability credentials. Worth it for damaged fine hair that needs treatment without the usual weight.
