Dr. Groot™ Hair Thickening Roll-On Serum is a precision-delivery scalp serum engineered to combat hair loss and stimulate new hair growth directly at the follicle. Its roll-on appl icator ensures targeted, mess-free application right where it matters most — along the part, thinning zones, or hairline — without disturbing the rest of your hair. What it does: Delivers a concentrated blend of hair-activating ingredients (including caffeine, biotin, and plant stem cell extracts) directly onto thinning areas of the scalp, reawakening dormant follicles and reducing daily shedding over time. ✅ Roll-on applicator for precise, targeted scalp delivery ✅ Reduces visible hair shedding within 4–6 weeks of consistent use ✅ Stimulates dormant follicles for new hair density ✅ Lightweight, non-greasy formula — no residue, no white cast ✅ Leave-in formula — apply and go, no rinsing needed ✅ Suitable for men and women, all hair types Key ingredients: Caffeine • Biotin (Vitamin B7) • Adenosine • Capixyl™ peptide complex • Plant stem cell extract How to use: Part hair to expose the scalp. Roll directly onto the thinning area. Gently massage in with fingertips. Do not rinse. Apply morning or night — or both for accelerated results. Best for: Hair thinning at the crown, receding hairline, postpartum hair loss, stress-related shedding, and early-stage androgenetic alopecia. Dr. Groot's #1 bestselling scalp treatment — and the foundation of the Complete Hair Revitalizing System. Show more
