medicube Rosemary PDRN Scalp Serum 20ml — Lightweight, Non-Greasy Treatment with Cooling Gua Sha for Soothing, Fuller-Looking Hair

A lightweight, non-greasy scalp serum combining rosemary, PDRN, and EGF with a mini gua sha applicator to soothe, cool, and support a healthier-looking scalp.

This concentrated 20ml serum from medicube is designed for targeted scalp care: it soothes irritated, flake-prone skin, helps maintain a balanced environment at the roots, and preserves hair volume without weighing strands down. The formula layers rosemary with skin-supporting actives like PDRN and EGF, and includes ultra-fine spicules to spread ingredients evenly. The quick-absorbing texture and a cooling gua sha–style applicator make it simple to add focused scalp treatment to your routine after shampooing.

How does this serum calm an irritated or flake-prone scalp?

The serum blends botanical rosemary with PDRN and EGF to condition and soothe the scalp surface. It focuses on maintaining a balanced environment where healthy-looking hair can appear fuller, while the cooling applicator provides immediate relief during application.

• Rosemary extract for calming sensation and scalp conditioning
• PDRN and EGF to support skin-repair supporting ingredients
• Cooling gua sha applicator to reduce heat and offer a soothing massage
• Fast-absorbing, non-greasy base to avoid residue

Will this product weigh my hair down or leave it greasy?

No — the formula is formulated to be lightweight and fast-penetrating so it won’t flatten roots or leave an oily finish. You can use it on towel-dried hair without compromising style volume, making it suitable for daily or targeted use.

• Non-greasy serum base that absorbs quickly into the scalp
• Designed to maintain hair volume and root lift
• Suitable for use before styling or on days between washes
• Leaves minimal visible residue when massaged in properly

How do I use the gua sha applicator and spicules for best results?

Apply directly to a towel-dried scalp after shampooing, then massage gently with the built-in mini gua sha for improved absorption and a cooling sensation. Ultra-fine spicules help distribute active ingredients evenly, so a light, methodical application is enough.

• Remove excess water from hair so serum contacts scalp efficiently
• Squeeze a small amount onto the applicator tip and apply along the parting
• Use the gua sha edge to massage each section for 10–20 seconds
• Do not rinse out; style as usual once the product is absorbed

What makes this formula different from other scalp serums?

The distinguishing elements are the triple-active composition and application design: rosemary plus PDRN and EGF create a targeted scalp-support complex, while spicules and a gua sha applicator enhance delivery and user experience. Together they prioritize scalp comfort and manageable hair volume.

• Triple-active scalp complex for multi-faceted conditioning
• Ultra-fine spicules for even ingredient distribution
• Mini gua sha applicator for cooling, hands-free massage
• Concentrated 20ml size for targeted, on-demand use

Who is this for: medicube Rosemary PDRN Scalp Refresh & Nourish Serum is suited to anyone looking for a lightweight, focused scalp treatment — especially those with sensitive, flake-prone, or easily irritated scalps who want a non-greasy option that preserves hair volume. It’s also a good choice for people who prefer targeted, post-shampoo application with a soothing, cooling massage step.
