From the Research
For hair loss treatment, the most effective dosing of minoxidil is 2% solution twice daily for women and 5% solution or foam twice daily for men, as supported by the most recent study 2.
Minoxidil Dosing
The dosing of minoxidil for hair loss treatment varies between men and women.
- Men typically use a 5% solution or foam applied twice daily.
- Women generally use a 2% solution twice daily or 5% solution once daily. Each application requires about 1 ml of solution or a half-capful of foam, applied to dry scalp in the thinning areas and gently massaged in.
Consistency and Results
Consistency is crucial - minoxidil must be used continuously to maintain results, as stopping treatment will cause new hair growth to be lost within 3-4 months. Results take time, with initial improvements often visible after 4 months and optimal results after about 12 months of regular use.
Mechanism of Action and Side Effects
Minoxidil works by extending the growth phase of hair follicles and increasing follicle size, improving blood flow to the scalp. Side effects may include scalp irritation, unwanted hair growth elsewhere if the solution drips, and initial increased shedding in the first few weeks, which is actually a sign the medication is working as new hairs push out old ones.
Alternative Treatment Options
Oral minoxidil at low dose has been proposed as a safe alternative to topical minoxidil, with studies showing its efficacy and safety in treating hair loss 3, 4, 5. However, the most recent and highest quality study 2 supports the use of topical minoxidil as the primary treatment option.
Patient Satisfaction and Treatment Response
Patient satisfaction and treatment response may vary depending on the individual, with some studies showing significant differences in treatment response between men and women 2. Overall, minoxidil is a effective treatment option for hair loss, with the most effective dosing being 2% solution twice daily for women and 5% solution or foam twice daily for men.
