From the Research
Minoxidil can be used to treat female hair loss, while finasteride is generally not recommended for women. For women experiencing hair loss, topical minoxidil 2% is FDA-approved and available over-the-counter, though some dermatologists may recommend the 5% solution for better results, as shown in a study published in 2014 1. Women should apply minoxidil to the scalp twice daily, and consistent use for at least 4-6 months is necessary to see results, with continued application required to maintain any hair regrowth. Minoxidil works by prolonging the growth phase of hair follicles and increasing blood flow to the scalp.
Key Points to Consider
- A randomized, placebo-controlled trial published in 2004 demonstrated the efficacy of 5% topical minoxidil in treating female pattern hair loss, with significant improvements in hair count and patient assessments of hair growth/scalp coverage 2.
- A more recent study from 2024 compared the effectiveness and safety of topical minoxidil versus 1 mg daily oral minoxidil, finding that both treatments showed significant improvement in hair diameter, although topical minoxidil had a better overall therapeutic effect 3.
- Finasteride, however, is contraindicated for women of childbearing potential due to the risk of birth defects in male fetuses if taken during pregnancy, and clinical studies have not shown it to be effective for female pattern hair loss in most cases.
- Women experiencing hair loss should consult with a dermatologist for proper diagnosis and treatment recommendations, as female hair loss can have various causes including hormonal imbalances, nutritional deficiencies, or underlying medical conditions that may require different approaches.
Treatment Options
- Topical minoxidil 2% or 5% solution applied twice daily to the scalp
- Oral minoxidil 1 mg daily, which may be as effective and safe as standard topical minoxidil in female and male pattern hair loss, according to a study published in 2024 3
- Consultation with a dermatologist to determine the best course of treatment and rule out underlying medical conditions.
