What it is The Medicube Rosemary PDRN Scalp Serum is a concentrated, lightweight leave-on scalp treatment meticulously designed to combat the look of flat, thinning hair and dry, flake-prone hair roots.

Utilizing advanced spicule texturizing technology alongside botanical extracts, it optimizes surface absorption to fortify fragile strands from root to tip. This fast-absorbing serum improves overall scalp hydration and surface vitality, creating an optimal conditioning foundation for a visibly thicker, denser, and fuller-looking hairstyle.
