Minoxidil, once a hypertension medication, is finding renewed popularity as dermatologists prescribe it in low doses in pill form for hair loss treatment. Recent studies suggest that orally administered minoxidil may be more effective than topical applications. This trend is partly driven by telehealth companies, which facilitate easy access to prescriptions and medications. When it was introduced as Rogaine in the late 1980s, minoxidil was a breakthrough for treating male pattern baldness. Experts note its blood circulation-boosting properties aid in hair retention and growth.
"By increasing blood flow to the scalp it signals hairs to stay in their growth phase for longer," said Dr. Adam Friedman, chair of dermatology at George Washington University.
The practice follows a handful of recent studies suggesting the ingredient works as well - and possibly better - when swallowed, rather than applied to hair follicles on the head.
