Olaplex N°.0.5 Scalp Longevity Treatment
Leave-in scalp treatment for all hair and scalp types
A leave-in scalp treatment (No.0.5) targeting scalp health and longevity. Applied and left in — no rinsing required. Designed for all hair and scalp types. A relatively niche addition to the Olaplex lineup; less relevant for most curlies than the core bond-building products, but worth considering if scalp health is a specific concern alongside damaged hair.
