oneskin OS-01 Hair Peptide Scalp Serum 50 mL — reduces shedding and supports thicker-looking hair, lightweight daily concentrate

oneskin OS-01 HAIR Peptide Scalp Serum is a daily topical concentrate formulated to help reduce hair shedding and support thicker-looking hair by nourishing the scalp and reactivating the hair cycle.

Designed for people noticing increased fallout or thinning areas, this lightweight 50 mL serum uses the proprietary OS-01 Peptide™ to target scalp health and hair density without greasy residue. The formula is intended for simple daytime or nighttime use and is clinically tested for improvements in hair density when used as directed. It absorbs quickly and layers easily with other styling products, making it suitable for routine grooming.

How does the OS-01 Peptide™ support hair density?

The OS-01 Peptide™ is a targeted ingredient designed to interact with the scalp environment to promote conditions favorable for hair to appear fuller. While not a miracle cure, studies cited by the brand report measurable gains in hair density with consistent application.

• Targets scalp environment to create favorable growth conditions
• Formulated to be lightweight for daily use
• Clinically evaluated for improved hair density in study participants

How should I use this serum in my daily routine?

Apply a few drops directly to dry or towel-dried scalp at the sites of concern, gently massage to distribute, and leave in—no rinsing required. The serum is suitable for both morning and evening routines and works under styling products.

• Daytime: apply in the morning before styling
• Nighttime: apply before bed for overnight absorption
• Use consistently for recommended results

What results can I expect and when might I see them?

Results vary by individual, but brand testing indicates visible changes in hair density with regular use over weeks to months. Initial reductions in shedding may be noticeable sooner, while fuller density typically requires longer-term, consistent application.

• Early: reduced shedding for some users within weeks
• Medium: improved scalp nourishment and hair feel in 4–8 weeks for many
• Long-term: measurable density improvements reported in clinical evaluations

Is this serum compatible with other hair or scalp treatments?

The OS-01 serum is formulated to layer well with most grooming and styling products, but always patch-test when combining active treatments. If you use medicated or prescription scalp therapies, consult a professional before adding new actives.

• Pairs with daily shampoos and conditioners
• Works under styling products without greasiness
• Consult a clinician if combining with prescription scalp medications
