medicube Scalp Serum with Rosemary PDRN — 20ml lightweight, non-greasy scalp treatment for thicker, soothed roots

medicube Scalp Serum with Rosemary PDRN is a lightweight, non-greasy 20ml scalp treatment designed to soothe flake-prone scalps and support thicker, fuller-looking hair from the roots.

This concentrated Korean scalp serum combines rosemary extract, PDRN, and EGF in a cooling, fast-absorbing formula that targets stressed scalps. A built-in mini gua sha applicator and ultra-fine spicules help deliver actives evenly while providing a calming massage and a rapid cooling sensation. The texture is formulated to settle quickly so it won’t leave hair feeling weighed down, making it easy to add to your post-shampoo routine.

How does this serum soothe a sensitive or flake-prone scalp?

The formula includes rosemary and a targeted complex designed to help calm the scalp and reduce visible flakiness after cleansing. Cooling actives and the gua sha applicator work together to provide immediate comfort while promoting an environment that supports healthier-looking hair growth patterns.

• Rosemary extract for plant-based soothing and balance
• PDRN and EGF to support scalp condition
• Cooling sensation from the applicator for instant relief
• Fast absorption that avoids residue build-up

Will this serum add weight or greasiness to my roots?

No — the serum is formulated to be lightweight and non-greasy so it leaves hair volume intact. It absorbs quickly into the scalp rather than coating strands, which helps maintain natural lift at the roots while delivering the active complex where it’s needed.

• Thin, fast-absorbing texture preserves root volume
• Non-oily finish suitable for daily or occasional use
• Mini gua sha applicator applies product precisely to the scalp
• Works under styling products without causing heavy buildup

How do I use the medicube Scalp Serum for best results?

Apply the serum after shampooing when hair is towel-dried to remove excess water. Direct the applicator to the scalp, dispense a small amount, and gently massage to help absorption; leave in—no rinsing required.

• Towel-dry hair after cleansing for better contact with the scalp
• Apply serum directly along the parting or problem areas
• Use the gua sha-style tip to massage until product absorbs
• Can be used as part of daily or weekly scalp-care routines

What makes the applicator and texture different from other serums?

The serum’s ultra-fine spicules help spread ingredients evenly across the scalp while the gua sha applicator provides a tactile cooling massage. Together they deliver targeted application and sensory feedback, ensuring the product reaches the scalp rather than remaining on hair strands.

• Spicules distribute serum uniformly across the scalp surface
• Gua sha applicator creates a soothing, cooling effect
• Compact 20ml size for trial or travel convenience
• Designed to apply directly to scalp for precise care
