Obagi Nu-Cil Biostim Scalp Serum 60ml

Obagi's scalp serum, launched in October 2025. Nu-Cil BioStim Scalp Serum (60ml) is a daily leave-in serum that supports the scalp and existing hair follicles for visibly fuller, denser-looking hair. In Obagi's 2025 24-week clinical test, hair volume improved by 52%, scalp redness reduced by 29% and scalp oiliness by 22%, compared with an untreated control group.*

Who it's for

All hair types and textures. Thinning, breakage, and dry or flaky scalps. It's a cosmetic product rather than a treatment for pattern hair loss; if you have significant hair loss, see a dermatologist. Consult a healthcare provider if pregnant or nursing.

Key ingredients

The BioStim Complex: biotin, amino acids and peptides with 18 hair nutrients including caffeine, panthenol, niacinamide, ginseng root and pumpkin seed extract. Fast-absorbing, non-greasy and fragrance-free.

How to use

Once a day. Part the hair, dispense directly onto the scalp and massage in with fingertips. Dry or damp hair, no rinsing. One tube lasts around four to twelve weeks depending on use. Participants in Obagi's study reported positive results from two weeks, with the volume result measured at under six months.

Face Perfect says

We've had a lot of questions about this one since launch. It's a commitment product: daily, for months. Start it and stick with it.
