Refilled cADPR Booster Plus scalp serum — hair growth serum for sensitive scalp, hydrating non-greasy

Refilled cADPR Booster Plus is a lightweight scalp serum that combines cADPR and NAADP cytokine technology with biotin to hydrate the scalp and support the look of fuller hair.

The Refilled cADPR Booster Plus Hair Growth Serum is designed for people with normal to dry, sensitive scalps who want gentle daily support for scalp comfort and fuller-looking hair. Built on Korean scalp science, the formula pairs patented cADPR cytokine technology with moisturizing agents and a built-in applicator to make targeted application quick and comfortable.

How does this serum help a dry or sensitive scalp?

The serum is formulated to deliver lightweight moisture and calm to areas prone to dryness or irritation without leaving a greasy residue. Ingredients are selected to absorb quickly while supporting scalp comfort, making it suitable for daily use.

• Light, fast-absorbing base reduces stickiness
• Moisture-rich actives to soothe and hydrate
• Non-greasy finish that layers well with styling products

What makes the cADPR cytokine technology different?

Refilled’s proprietary cADPR and NAADP cytokine complex is developed to interact with scalp biology in ways distinct from ordinary conditioners or oils. It focuses on supporting scalp wellness as part of a routine rather than claiming clinical cures.

• Patented cADPR + NAADP cytokine blend for targeted scalp care
• Formulated to complement regular maintenance routines
• Designed and tested with Korean scalp science expertise

How do I apply it and what is the applicator for?

The bottle includes an integrated scalp massager applicator to deliver serum directly to roots and problem spots. The applicator helps spread product evenly while gently stimulating the scalp for a more comfortable daily ritual.

• Use on dry or towel-dried scalp for targeted application
• Press gently and glide applicator along part lines and thinning areas
• Massage briefly to encourage even distribution and absorption

Can I use this every day with other hair products?

Yes — the lightweight, non-greasy formula is designed for consistent daily use and sits well under styling products. It can be included in morning or evening routines for ongoing scalp maintenance.

• Pairs easily with shampoos, conditioners, and styling formulas
• Fast absorption minimizes product buildup
• Suitable as part of a regular care routine for sensitive scalps
