Finasteride is a cornerstone treatment for androgenetic alopecia, commonly known as pattern hair loss. Rather than stimulating new growth alone, finasteride works by addressing the hormonal cause of follicle miniaturization, helping preserve existing hair and slow further loss.
Early intervention often leads to better long-term outcomes.
How Finasteride Works
Finasteride reduces levels of dihydrotestosterone (DHT), a hormone responsible for shrinking hair follicles over time. By lowering DHT, finasteride helps prevent continued follicle damage and supports healthier hair growth cycles.
This mechanism allows follicles to maintain thickness and function longer, particularly in areas prone to genetic hair loss.
Long-Term Hair Preservation
Consistent use of finasteride can help stabilize hair loss and maintain density over time. Results are gradual and require ongoing treatment, as stopping medication may lead to resumed hair shedding.
Medical Oversight Matters
A healthcare provider can determine appropriate dosing, discuss potential side effects, and monitor progress. When used correctly, finasteride remains one of the most effective and well-studied treatments for pattern hair loss.
