Refilled cADPR Scalp Serum Booster Plus — Lightweight, Non-Greasy Hydrating Scalp Tonic

Refilled cADPR Booster Plus is a lightweight scalp serum that combines proprietary cADPR cytokine technology with biotin to support balanced, hydrated scalp conditions and the appearance of fuller hair without greasy residue.

This daily-use tonic is formulated for normal to dry, sensitive scalps that need targeted moisture and gentle support for thin or weakened hair. The fast-absorbing formula delivers cytokines (NAADP and cADPR) alongside biotin in a non-greasy base, and the bottle includes an integrated applicator to make precise scalp application and gentle massage effortless.

How does this serum help a dry, irritated scalp feel more comfortable?

The formula provides lightweight hydration and soothing support designed to reduce tightness and visible dryness without leaving heavy residue. Ingredients are selected to promote scalp balance and to help maintain a comfortable surface environment day after day.

• Fast-absorbing base that hydrates without greasiness
• Cytokine blend (NAADP and cADPR) aimed at scalp wellness support
• Biotin for strengthening hair shaft appearance
• Designed for sensitive scalps with minimal irritation potential

Will the serum weigh hair down or make roots look oily?

Refilled cADPR Booster Plus is formulated to be lightweight and non-sticky so it won't flatten roots or create visible oil. Applied directly to the scalp and massaged in with the built-in applicator, the product is absorbed quickly and leaves hair touchable and natural-looking.

• Low-viscosity texture absorbs rapidly
• Non-greasy finish keeps volume intact
• Targeted scalp delivery minimizes product on hair strands
• Daily-use design for consistent, subtle results

What makes the cADPR cytokine technology different from other tonics?

How do I apply the serum for best results?

Use the integrated scalp massager to apply the serum precisely where you need it—part hair, dispense, and massage gently into the scalp. Regular, consistent application helps maintain moisture balance and keeps the formula working on the areas you target.

• Part hair into sections and place applicator on the scalp
• Dispense a small amount and massage with the built-in tip
• Use daily or as directed for routine scalp care
• Apply to dry or towel-dried scalp for best absorption
