Meet Celestine Rosemary Precision Hair Serum — a lightweight, leave-in scalp serum created for the part line, temples and crown. The easy roll-on applicator brings nourishing care directly to the spots you want to focus on, with no oily finish or rinse required.
15 ml / 0.5 fl oz · Cosmetic scalp-care serum

Not every part of your scalp needs the same attention. Apply exactly where you want a more thoughtful routine — whether that's your visible part, hairline or crown. Small moments of care can fit naturally into your morning or evening.

Designed to soothe and moisturize the scalp for a more comfortable daily care experience.
A fast-absorbing, non-greasy texture made to leave hair feeling light and easy to style.
The roll-on glides over selected areas with less mess than a traditional oil dropper.
Created to complement a routine focused on hair that appears healthier, stronger and fuller.

The rounded applicator is designed to deliver serum to specific scalp areas instead of coating every strand.
The brand highlights a 14-ingredient formula, including these scalp-care favorites. The complete INCI list should be checked on the actual package.
The botanical centerpiece, included to support a refreshed, comfortable scalp feel.
Vitamin B7, a familiar cosmetic hair-care ingredient associated with healthy-looking hair.
Commonly used in scalp products for a fresh, revitalized sensation.
The listing also names niacinamide, panthenol and an amino-acid complex.
Unlike a heavy rosemary oil routine, this leave-in serum is formulated to absorb quickly with no greasy coating. Massage it in, allow it to settle, and style your hair as you normally would.

Two easy steps fit into a morning refresh or an evening wind-down.
Part your hair if needed. Glide the roller gently over the part line, temples or crown where you want targeted care.
Use clean fingertips to massage gently. Leave the serum in place; there is no need to rinse before styling.

Use your regular shampoo to cleanse your hair and scalp on wash days. Reach for the precision serum when you want targeted leave-in care, without an extra wash or elaborate routine.
