Reducing scalp DHT doesn't directly correlate with preventing hair miniaturization, as different follicles have varying sensitivity levels. Dutasteride at 0.5 mg and 2.5 mg shows minimal visual difference in hair regrowth, with side effects being a consideration for higher doses.
The user is experiencing gradual hairline regrowth with finasteride and is considering increasing the concentration of topical finasteride and minoxidil to speed up growth. They are also using microneedling and considering adding tretinoin to their routine.
Significant hair regrowth was achieved using finasteride and 2.5mg oral minoxidil over a year, despite initial shedding. The treatment is recommended, though it may cause increased heart rate and body hair growth.
