Dr.Reju-All PDRN Hair Density Scalp Serum Roll-On 0.5 fl oz — High‑Concentration PDRN & Exosomes

Dr.Reju-All Advanced PDRN Hair Density Scalp Serum is a lightweight Korean scalp treatment serum formulated with high-concentration PDRN, SoyAct, and exosomes to support a healthier-looking scalp and fuller root appearance.

This concentrated 0.5 fl oz roll-on serum was developed in Korea by doctors and pharmacists and is designed to fit into nightly and daily scalp-care routines. It focuses on improving the condition of scalp skin with calming rosemary, a nonsticky texture for easy absorption, and a metal ball applicator for a cooling massage. The formula targets flaky, dry, or stressed scalp areas while providing ingredients intended to support reduced visible shedding and enhanced root volume.

How does this serum fit into my daily or nightly hair care routine?

Use the roll-on applicator on clean, dry or towel-dried scalp areas where you want to improve scalp condition and root appearance. Apply a few targeted rolls, gently massage with fingertips or the metal ball, and allow the lightweight formula to absorb; it is safe for daily use according to routine needs.

• Apply after cleansing or at bedtime for overnight treatment
• Use the metal ball for a cooling, even distribution
• Non-greasy texture layers easily under topical styling products

What are the key ingredients and what do they contribute?

The serum combines high-purity PDRN (99%) with 2% SoyAct and 1,000 ppm exosomes to support scalp skin conditioning and a healthier-looking hair cycle. Rosemary extract adds a cooling, soothing effect while the formulation remains lightweight for quick absorption.

• PDRN 99%: high-concentration ingredient for scalp conditioning support
• SoyAct 2%: contributes to cycle-focused scalp care
• Exosomes 1,000 ppm: included to support scalp environment balance

Will this reduce visible hair shedding and improve volume?

The serum is formulated to help decrease the appearance of shedding and promote fuller-looking roots by improving scalp condition and supporting the hair cycle. Results vary by individual; consistent application paired with proper hair care increases the likelihood of noticing improved volume appearance over time.

How do I use the metal ball applicator and how much product is needed?

The metal ball is designed for clean, precise application and a refreshing massage feeling. Roll the applicator slowly across targeted sections, then lightly massage; a little product goes a long way because of the concentrated formula.

• Apply 2–6 rolls per targeted area depending on coverage needed
• Massage gently; leave on overnight or let absorb before styling
• Store upright and replace cap to keep applicator sanitary
