Dr.Reju-All Advanced PDRN Scalp Serum, 0.5 fl oz – Roll-On Exosome + SoyAct for Fuller-Looking Hair & Soothing Flaky Scalp

This concentrated 0.5 fl oz scalp serum blends clinical-grade ingredients developed by dermatology and pharmacy teams in Korea to target the scalp as skin. The fast-absorbing formula is designed for daily use: a cooling metal-ball applicator lets you apply and gently massage the serum directly into flake-prone, dry, or stressed areas to refresh the scalp overnight or during the day.

How does this serum help improve scalp condition?

The product focuses on restoring a healthier scalp surface by delivering moisturizing and soothing actives where hair begins. Instead of a thick cream, it uses a lightweight liquid backbone that absorbs quickly and leaves no sticky residue.

• Contains concentrated PDRN to support skin-layer nourishment.
• Includes 1,000 ppm exosome complex for targeted scalp conditioning.
• SoyAct (2%) supports cyclical scalp and hair health.
• Rosemary extract adds a cooling, calming effect after application.

What results can I expect with regular use?

With consistent application, the serum aims to reduce the appearance of excess shedding and improve the look of density at the roots, while making the scalp feel less irritated. Results depend on individual scalp condition and routine consistency.

• Supports fuller-looking hair and improved root volume visibility.
• Helps soothe flaky or dry scalp areas for smoother skin texture.
• Light formula is suitable for daily morning or nightly routines.
• Metal ball applicator delivers a refreshing cool touch to the scalp.

How is this serum best applied in a hair care routine?

Use the roll-on applicator to apply serum directly to the scalp at targeted points, then lightly massage to spread the product and stimulate circulation. It is appropriate as a stand-alone scalp treatment or layered under other hair-care products as part of a K-beauty inspired regimen.

• Part hair and roll applicator along the hairline and scalp sections.
• Gently massage for 10–20 seconds to promote absorption and cooling.
• Leave on overnight for best contact time; no rinsing required.
• Can be used daily on dry or slightly damp hair.

Is this product safe for sensitive or flake-prone scalps?

Formulated by doctors and pharmacists, the serum emphasizes gentle actives and lightweight delivery suitable for many sensitive scalps, but as with any concentrated topical product, patch testing is wise for those with reactive skin. The soothing botanicals and fast-absorbing texture aim to reduce discomfort while nourishing the scalp area.

• Developed with clinical oversight and placed in thousands of Korean pharmacies.
• Cooling rosemary component to relieve minor irritation sensations.
