Hello, Thank you for posting on HCM. Minoxidil is mostly used for hairfall conditions because of its property to increase blood supply to hair follicles and thereby leading to increased hair growth. Recent studies also demonstrate that minoxidil also increases the production and supply of growth factors required for hair growth. Usually, its advocated for long term use (months-years) to appreciate good results. Even years of therapy has not produced any side effects however caution should be maintained in patients having hypertension and migrane. Hope the answer was useful. Thank you Dr Hardik Pitroda
