From the Research
Topical minoxidil is a highly effective treatment for female pattern hair loss, and the most recent and highest quality study recommends its use in combination with microneedling for optimal results. According to the study published in 2022 1, the combination of 5% topical minoxidil and microneedling resulted in significant improvements in hair density, hair shaft diameter, and patient satisfaction, making it a better choice than minoxidil alone or minoxidil plus oral spironolactone.
The FDA-approved treatment is available over-the-counter in 2% and 5% solutions, with the 2% concentration typically recommended for women (applied twice daily) 2. Women should apply 1 mL of the solution directly to the scalp in thinning areas and allow it to dry completely before styling. Results typically take 4-6 months to become noticeable, and continued use is necessary to maintain benefits, as hair loss will resume if treatment is stopped.
Minoxidil works by extending the growth phase of hair follicles and increasing blood flow to the scalp, which helps revitalize shrunken follicles 3. Side effects may include scalp irritation, unwanted facial hair growth (particularly with the 5% solution), and initial increased shedding during the first few weeks of treatment. Women who are pregnant, breastfeeding, or have scalp conditions should consult a doctor before use.
Some key points to consider when using topical minoxidil for female pattern hair loss include:
- Applying the solution directly to the scalp in thinning areas
- Allowing the solution to dry completely before styling
- Using the solution consistently, as directed, for optimal results
- Being patient, as results may take several months to become noticeable
- Combining minoxidil with other treatments, such as microneedling, for enhanced results
- Monitoring for side effects and adjusting treatment as needed.
Overall, topical minoxidil is a safe and effective treatment for female pattern hair loss, and its use in combination with microneedling may provide optimal results 1.
