Supplemental Figure 1 for Time to Maximal Response with Low-Dose Oral Minoxidil in Clinical Treatment of Androgenetic Alopecia

Oral dutasteride 0.5 mg combined with oral minoxidil 2.5 mg is highly effective for male androgenetic alopecia, showing over 60% improvement and 98% stabilization at 6 months, with low adverse event rates. Patients with severe baseline conditions respond better and faster to this treatment.

A user shared their 1-year and 3-month hair loss treatment progress using 0.5mg Dutasteride daily, topical and then oral Minoxidil, and microneedling, noting hair darkening and some side effects like watery semen and testicular pain. Despite initial setbacks after switching to oral Minoxidil, they are seeing progress and plan to increase the dosage.

Minoxidil's effectiveness varies due to genetic differences in the SULT1A1 enzyme, affecting how well it converts to its active form, minoxidil sulfate. Hyper-responders may experience rapid hair growth and increased side effects, such as pericardial effusion, even at low doses.

Oral minoxidil, finasteride, and dutasteride are being used to treat hair loss, but results are limited, leading to consideration of a hair transplant. The user plans to continue medication for another year before deciding on further action.

Oral minoxidil dosing should be based on body weight to minimize side effects, with higher doses increasing risks like pericardial effusion. Combining oral minoxidil with topical treatments and finasteride can improve hair growth, but regular heart health monitoring is essential.

High-dose oral minoxidil (>5 mg/day) can increase hair density in some men with androgenetic alopecia, but side effects like extra body hair and heart issues are common. Gradual dose increase is advised, but adverse effects may lead to discontinuation or dose adjustments.
