Regaine is a clinically proven topical treatment for hereditary hair loss (androgenetic alopecia) in men and women, containing the active ingredient minoxidil. Applied directly to the scalp, it works by revitalising shrunken hair follicles to stimulate regrowth and slow further thinning.
Benefits: Non-prescription; suitable for regular use as part of a hair care routine; available as solution or foam; results typically assessed over 4 months of consistent use.
Side effects: Scalp irritation, itching, or dryness is common. Rare but serious effects include unexpected weight gain, swelling of hands/feet, chest pain, rapid heartbeat, or dizziness — anyone experiencing these should stop use and see a doctor. Not suitable for use on broken, irritated, sunburnt, or shaved scalp, or in pregnancy/breastfeeding.

Regaine contains minoxidil, which helps stimulate hair follicles and encourage hair regrowth in people with hereditary hair loss. Apply exactly as directed to a clean, dry scalp and continue treatment consistently, as visible improvement may take several months. Common side effects include scalp irritation, itching and dryness. Wash your hands after application and seek medical advice if you experience chest pain, dizziness or persistent scalp irritation.
