From the Research
For women with hair loss, the recommended dosage of topical minoxidil is typically 2% or 5% solution applied twice daily, as both concentrations have been shown to be effective in promoting hair growth and reducing shedding 1. When using topical minoxidil, apply 1 mL of the solution directly to the scalp in the affected areas each time, using the provided dropper or spray applicator. Ensure the scalp is dry before application and allow the solution to dry completely before styling hair or going to bed. Results typically take 4-6 months to become noticeable, and consistent daily use is necessary to maintain any hair regrowth. If you stop treatment, any new hair growth will likely be lost within 3-4 months. Side effects may include scalp irritation, unwanted facial hair growth (particularly with higher concentrations), and initial increased shedding in the first few weeks of treatment. Minoxidil works by prolonging the growth phase of hair follicles and increasing blood flow to the scalp, which helps revitalize shrunken follicles. Some studies suggest that combining topical minoxidil with other treatments, such as spironolactone, may lead to improved outcomes 2. However, the most recent and highest quality study on the topic of topical minoxidil dosing for women does not specifically address combination therapy 1. If no improvement is seen after 12 months of consistent use, consider consulting a dermatologist for alternative treatments. Key points to consider when using topical minoxidil include:
- Apply the solution to a dry scalp
- Allow the solution to dry completely before styling hair or going to bed
- Be patient, as results may take 4-6 months to become noticeable
- Consistent daily use is necessary to maintain hair regrowth
- Monitor for side effects, such as scalp irritation or unwanted facial hair growth.
