The Pharmacokinetics of 2.5- to 10-mg Oral Doses of Minoxidil in Healthy Volunteers

A 44-year-old man experienced significant hair regrowth after switching from topical to 1.25mg oral minoxidil and 0.5mg daily finasteride, with no side effects. He noticed hair thickening after two months and credits the oral form's effectiveness.

The conversation discusses the effectiveness and side effects of taking 1.25mg oral minoxidil for hair loss, with some users suggesting starting at a lower dose to minimize side effects before potentially increasing to 2.5mg. Concerns about cardiovascular side effects and the importance of individual responses to dosage are highlighted.

The user stopped taking 5 mg oral minoxidil after 15 days due to side effects and is experiencing hair shedding. They are now using topical minoxidil on temples and corners and have used oral finasteride for a year, seeking advice on hair regrowth and shedding duration.

New hair growth from minoxidil and finasteride is not reaching full length, possibly due to slow growth cycles. Users discuss dosing strategies for oral minoxidil to improve efficacy and minimize side effects, with advice against consuming topical minoxidil orally.

Minoxidil 1.25mg twice daily is recommended by experts for better hair growth due to its short half-life, while some users report success with higher doses like 5mg. Oral minoxidil is becoming more popular than topical forms, with some users experiencing side effects like dizziness and palpitations.

Oral minoxidil and finasteride can lead to quick hair growth, with some users noticing changes in as little as 2-3 weeks, though head hair may take longer. Many prefer oral minoxidil over topical due to convenience, and some also use ketoconazole shampoo and other topical treatments.
