Minoxidil, originally developed in the 1970s as a medication for high blood pressure, is gaining attention as an oral treatment for hair loss.
Previously known in its topical form as Rogaine, the drug is now being prescribed in low-dose pill form, with dermatologists citing its potential convenience and effectiveness.
Minoxidil works by improving blood circulation to the scalp, extending the growth phase of hair follicles.
While its topical version was FDA-approved for hair loss in the 1980s, many dermatologists now support the oral form due to its ease of use and higher patient adherence.
Oral minoxidil is absorbed more efficiently and requires only once-daily dosing, compared to the twice-daily application of the topical solution.
Despite its potential benefits, oral minoxidil has not been FDA-approved specifically for hair loss.
Since the drug’s patent has expired, pharmaceutical companies have little financial incentive to conduct the necessary studies for official approval.
Dermatologists often prescribe it off-label, with a month’s supply costing as little as $5.
Minoxidil is one of two FDA-approved medications for hair loss, alongside finasteride (Propecia), which works by blocking a testosterone byproduct linked to male pattern baldness.
While finasteride is considered more potent, it has potential side effects, including sexual dysfunction. Some dermatologists recommend combining both medications for improved results.
However, many dermatologists advocate for traditional in-person consultations for comprehensive evaluations, including blood pressure checks and thorough discussions about medical history and potential side effects.
“I’m not a proponent of going to an online service,” Dr. Taylor advises, emphasizing the importance of consulting board-certified dermatologists who can provide a holistic assessment.
