Our Take

A hydrating in-shower mask with Olaplex bond-building technology, formulated specifically for fine to medium hair. Olaplex positions this alongside the Rich Hydration Mask and recommends choosing based on hair thickness — this one for fine to medium, the Rich version for medium to thick. Use in place of your regular conditioner once or twice a week. Contains silicones (cgm_modified). The lighter texture makes it a better fit for fine-haired curlies (2a–3b) than the richer mask.
