medicube Rosemary PDRN Scalp Refresh & Nourish Serum 20ml — Lightweight, Non-Greasy Scalp Treatment with Gua Sha Applicator

This concentrated Korean scalp serum combines a triple-active complex and ultra-fine spicules to deliver targeted care to stressed, flake-prone scalps without weighing hair down. The quick-absorbing formula cools and calms the scalp on contact and includes a mini gua sha–style applicator to help spread the product evenly and massage the scalp for improved comfort and coverage.

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

The formula includes rosemary extract plus PDRN and EGF to help condition and soothe irritated scalps while promoting a balanced scalp environment. It focuses on surface calming and visible improvement in scalp appearance rather than treating underlying medical conditions.

• Soothing rosemary extract to reduce surface redness and irritation.
• PDRN and EGF to support a healthier-looking scalp environment.
• Fine spicules for more even topical application across the scalp.
• Cooling sensation on contact to relieve immediate discomfort.

Will it leave my hair greasy or weigh down my roots?

No — the serum is designed to be non-greasy and fast-absorbing so it won’t flatten hair or leave residue at the roots. You can use it after towel-drying to keep hair volume while providing targeted scalp care.

• Lightweight texture disperses quickly into the scalp.
• Formulated to maintain root lift and hair volume.
• Dries down without sticky or oily finish.
• Suitable for daily or as-needed topical use.

How do I apply the serum for best results?

Apply after shampooing and towel-drying: part hair, apply small amounts directly to the scalp, then use the mini gua sha applicator or fingertips to massage for better absorption. Regular, consistent use helps maintain a balanced scalp environment and even coverage.

• Use on slightly damp hair after cleansing.
• Apply concentrated drops directly to target areas.
• Gently massage with the gua sha applicator or fingertips for 30–60 seconds.
• No rinse required; style as usual after absorption.

What makes the applicator and spicules different from regular serums?

The built-in mini gua sha applicator creates a pleasant cooling effect while helping spread the serum evenly; ultra-fine spicules improve ingredient distribution across the scalp. These design elements aim to enhance the sensory experience and ensure more uniform topical delivery.

• Gua sha–style head for gentle massage and cooling contact.
• Spicules disperse product evenly along the scalp surface.
• Reduces need to rub excessively, lowering friction on hair roots.
• Compact 20ml size for trial or travel-friendly use.
