Refilled cADPR Booster Pro Hair Growth Serum — Intensive Scalp Treatment with Built-in Massager & Biotin

Refilled cADPR Booster Pro is an intensive scalp serum that targets thinning, weak hair with patented cADPR cytokine technology, biotin, and a built-in scalp massager for precise, non-greasy daily application.

This advanced Korean-derived hair tonic was formulated to support fuller-looking hair and stronger roots while caring for sensitive or unbalanced scalps. The lightweight, fast-absorbing formula combines Refilled’s proprietary cytokine complex (cADPR/NAADP) with nourishing biotin to help maintain a healthier scalp environment, manage excess sebum, and leave hair feeling less fragile. A convenient integrated applicator places product directly on the scalp for targeted treatment and easier daily use.

How does the cADPR Booster Pro help hair that looks thin or fragile?

The serum is designed to improve the appearance of density and root strength by delivering concentrated actives to the scalp. Rather than coating hair strands, the formula focuses on scalp condition and root support, helping hair look fuller over time when used consistently.

• Patented cADPR cytokine complex targets scalp signaling pathways associated with healthier-looking hair.
• Biotin supports the appearance of stronger-looking strands and improved texture.
• Lightweight serum absorbs quickly to avoid weighing hair down.
• Built-in applicator ensures precise placement at the roots for maximum effect.

Can this serum be used on sensitive or oily scalps?

Yes — the formulation is intended for sensitive and unbalanced scalps, with a non-sticky texture that minimizes irritation risk. It helps regulate excess sebum while providing a gentler approach compared with harsher tonics or sprays.

• Fast-absorbing base reduces residue and greasy buildup.
• Designed for daily use to support a balanced scalp environment.
• Suitable for normal-to-sensitive scalp types seeking moisture control.
• Concentrated application avoids unnecessary product contact with hair lengths.

How is the built-in scalp massager applicator useful in a hair-care routine?

The integrated applicator delivers serum directly to targeted spots on the scalp while gently massaging to enhance distribution and comfort. This makes the product easier to use consistently and helps ensure the actives reach the areas that need attention most.

• Ergonomic tip deposits serum at the scalp for precise coverage.
• Massaging motion helps spread the formula and promotes quick absorption.
• Reduces product waste by limiting application to the scalp rather than hair shafts.
• Portable design fits into daily grooming without extra tools.

What kind of results should I expect and how do I use it?

Results vary by individual, but consistent daily application can improve the look of density and root strength over time by improving scalp condition. Use the integrated applicator to part hair and apply the serum directly to the scalp; gently massage with the applicator tip and leave the formula to absorb—no rinsing needed.

• Apply daily to clean, dry or slightly damp scalp for best distribution.
• Part hair into sections and dispense a small amount along the scalp.
• Gently massage with the built-in tip; do not rinse out.
• Follow with regular styling; formula is non-greasy and lightweight.
