Safety and Tolerability of Low Dose Oral Minoxidil Monotherapy in Female Pattern Hair Loss: A Retrospective Review With Longitudinal Ambulatory Blood Pressure Monitoring

An 18-year-old woman experiencing hair loss due to stress, possible PCOS, and low vitamin D is concerned about starting 5% minoxidil foam, prescribed by her doctor, due to potential facial hair growth. She is also using a topical steroid for scalp sensitivity and pain.

Low-dose oral minoxidil is used for hair loss and does not significantly affect blood pressure but may increase heart rate and cause hypotensive symptoms. Some users experience side effects like palpitations and shortness of breath, while others find it effective; topical minoxidil with tretinoin is also considered.

The user experienced significant hairline improvement using 10mg oral minoxidil and 0.5mg dutasteride daily but also saw increased body and facial hair growth. They are considering reducing the minoxidil dose due to side effects and exploring laser hair removal options.

Daytime low-dose oral minoxidil may be more effective for treating androgenetic alopecia. Some users experience dizziness and headaches when taking it at night.

Low-dose oral minoxidil shows mixed results, with some users experiencing hair regrowth and others seeing no significant change. Finasteride is also commonly used, often in combination with minoxidil, and is generally considered effective with a low rate of side effects.

Oral minoxidil can cause severe side effects, including cardiac issues like shortness of breath and fluid retention, leading some users to stop its use. Many prefer topical minoxidil due to fewer systemic side effects, and there is anticipation for new formulations to minimize risks.
