FAQs
Q1. How does Minoxidil 5% in Regaine Solution stimulate hair regrowth?
A1. Minoxidil opens ATP-sensitive potassium channels in vascular smooth muscle, causing vasodilation and increased scalp blood flow. At the follicle level, it directly prolongs the anagen (growth) phase, shortens the telogen (rest) phase, and upregulates VEGF — a growth signal that expands and reactivates miniaturised follicles. Regaine 5% Solution delivers the clinically established concentration for male pattern hair loss, with evidence also supporting its use in female pattern hair loss under medical supervision.
Q2. Is Regaine 5% significantly more effective than 2% Minoxidil solutions?
A2. Clinical studies show 5% Minoxidil produces approximately 45% more hair regrowth than 2% at six months in men with androgenetic alopecia, with a faster onset of visible results. Women are generally started on 2% to reduce hypertrichosis (unwanted facial hair growth) risk, though some dermatologists prescribe 5% for women not responding to the lower concentration.
Q3. My hair fell out more after starting Regaine — should I stop?
A3. Do not stop. Increased shedding in the first four to eight weeks is expected and indicates the solution is working — Minoxidil forces resting telogen hairs to shed to make way for new anagen growth. This initial shedding phase resolves on its own and is followed by visible regrowth. Stopping Regaine 5% during this phase is the most common reason patients abandon a treatment that was actually beginning to work.
Q4. Does Regaine 5% need to be used indefinitely to maintain results?
A4. Yes. Minoxidil does not treat the underlying cause of androgenetic alopecia (DHT-mediated follicle miniaturisation) — it maintains follicles in an active growth state. Stopping Regaine 5% Solution causes regrown hair to shed within three to four months as follicles return to their pre-treatment pattern. Many dermatologists combine it with a DHT blocker for longer-term disease modification alongside regrowth maintenance.
Q5. Should I apply Regaine 5% to wet or dry scalp?
A5. Always apply to a completely dry, clean scalp. Water on the scalp dilutes the solution and reduces the effective concentration reaching follicular openings — a common but avoidable reason for suboptimal results. Apply 1 mL to the affected area, spread gently with fingertips, and avoid washing hair for at least four hours to allow full absorption.
