Olaplex N 0.5 Scalp Longevity Treatment (1.7 oz) - #0.5 Anti-Aging Serum for Hydrated, Healthy Scalp & Hair

Support scalp wellness with Olaplex No.5 Scalp Longevity Treatment, a forward-thinking serum crafted to hydrate, protect, and preserve the health of your scalp and hair. This weightless, leave-in formula targets scalp aging, one of the most overlooked factors in hair quality. With each application, it infuses hydration directly into the scalp, easing dryness, reducing sensitivity, and restoring balance to support long-term follicle health. Gentle yet effective, it’s suitable for all scalp and hair types and is dermatologist-tested and trichologist-approved. Whether used as a pre-styling step or an overnight treatment, this serum delivers visible improvements in comfort and shine with regular use.

Engineered with anti-aging science, this serum works by strengthening the scalp barrier and supporting the scalp's natural microbiome, two crucial factors in hair longevity. The precise needle-nose applicator allows for targeted delivery along the scalp line, reaching problem areas with ease. Apply to three or four sections around the crown and back of the head, then gently massage to activate absorption. Used consistently, it promotes softer, shinier, and visibly healthier strands from the source. The formula blends effortlessly without residue and layers seamlessly under other hair products, offering versatility for any routine and hair texture. It’s a treatment that starts where real hair health begins.

Combining hydration and scalp care into one multitasking essential, Olaplex has created a high-performance solution that enhances hair's appearance and resilience over time. The lightweight texture ensures it absorbs instantly, never making hair feel oily or heavy. By combating the accelerated aging that occurs at the scalp level, it helps maintain stronger strands and slows down visible hair degradation. It’s also gentle enough for daily use, whether applied post-shower to damp roots or left in overnight for extended nourishment. With continued use, this innovative formula becomes a cornerstone of a scalp-first, science-backed hair care routine designed for long-term beauty and wellness.
