Glowrenza Biotin Hair Growth Serum is a concentrated, lightweight formula designed to support stronger, fuller-looking hair. Infused with biotin, castor oil, and a blend of botanical extracts including ginseng and ginger, it delivers targeted nourishment to the scalp, helping to fortify weak hair from the root up. With a fast-absorbing, non-greasy texture, it’s an effortless way to upgrade your daily hair care routine β€” no pills, no harsh chemicals, just clean, effective ingredients.

Water (Aqua), Biotin, Ricinus Communis (Castor) Seed Oil, Panax Ginseng Root Extract, Zingiber Officinale (Ginger) Root Extract, Polygonum Multiflorum Root Extract.

Hold the bottle 2–3 inches away from the scalp and spray directly onto the desired areas.
Massage gently with fingertips to help the serum absorb.
Use once daily, preferably on a clean scalp.
For best results, apply consistently over a minimum of 3 months.
