How does this serum support scalp conditioning and comfort?

The formula includes soothing botanicals and delivery actives intended to address dry, flaky, or irritated scalp skin. Its cooling metal ball applicator helps to calm the scalp at the moment of application while the lightweight serum absorbs without stickiness.

• PDRN 99% concentration to supply bioactive nucleotides within a cosmetic formulation.
• Rosemary extract for a refreshing, cooling sensation and scalp comfort.
• Fast-absorbing base that reduces residue and greasiness on hair roots.

What ingredients help with the hair cycle and fuller-looking hair?

This product combines multiple actives to support a healthy-looking hair cycle and the appearance of volume. It pairs a soy-derived ingredient with exosome-containing concentrate and high PDRN levels to support hair density visually.

• SoyAct 2% to support hair cycle-related scalp care.
• Exosome complex at 1,000 ppm to help deliver bioactive signals in the formula.
• PDRN 99% as a concentrated feature of the serum blend.

How do you use the roll-on applicator for best results?

The metal ball roll-on is engineered for precise, clean application directly to the scalp with a pleasant cooling effect. Apply to targeted areas daily or nightly and gently massage; the formula is suitable for night care when left in place while you sleep.

• Part hair and roll the metal ball directly onto the scalp where needed.
• Gently massage with fingertips to distribute and aid absorption.
• Leave on overnight or until next wash; non-sticky texture fits daily use.

Is this product safe for sensitive scalps and daily routines?

The serum was developed by medical professionals and pharmacists and is positioned as a gentle scalp cosmetic. Its lightweight, non-greasy formulation and targeted cooling application suit regular use, though patch testing is recommended for very sensitive skin.
