The Oneskin OS-01 HAIR Peptide Scalp Serum is a leave-in treatment formulated to address hair shedding and support overall hair density. The serum features a peptide-based complex designed to interact with the scalp environment, targeting the root causes of thinning hair without relying on harsh chemicals or synthetic fragrances. Its lightweight, non-greasy texture absorbs quickly into the scalp, making it suitable for daily use across all hair types, including color-treated or chemically processed hair. The formula is free from sulfates, parabens, and phthalates, aligning with a clean beauty approach that prioritizes gentle yet effective ingredients.

Key to the serum’s function is its focus on the scalp as the foundation for healthy hair growth. Peptides in the formulation are intended to support the natural hair cycle by reinforcing the follicle environment, potentially reducing excessive shedding over consistent use. Unlike many hair treatments that target the hair shaft alone, this serum delivers active ingredients directly to the scalp, where hair growth begins. It works for both men and women experiencing temporary thinning or seasonal shedding, as well as those seeking to maintain existing hair density.

The serum is designed to be applied directly to a clean, dry or damp scalp, massaged gently into areas of concern. It layers well under other styling products and does not leave a visible residue. The product is packaged in a dropper bottle for precise application, minimizing waste. For best results, consistent daily application over several weeks is recommended, though individual response may vary based on the underlying cause of hair thinning. This serum does not claim to cure or reverse permanent hair loss but serves as a supportive tool for those prioritizing scalp health as part of a broader hair care routine.
