The Science Behind Hair Loss: Minoxidil, Finasteride, and Beyond

Androgenetic alopecia, commonly known as male pattern baldness, is responsible for the vast majority of hair loss in men. It's driven by a combination of genetics and hormones—specifically, dihydrotestosterone (DHT).

How DHT Affects Hair Follicles

In men genetically predisposed to hair loss, hair follicles at the crown and hairline are sensitive to DHT. Over time, DHT causes these follicles to miniaturize. The growth phase shortens, and the hair becomes thinner and weaker until the follicle eventually stops producing hair altogether.

Clinically Proven Treatments

Currently, the most effective approach to treating hair loss is a combination therapy targeting both blood flow and hormone levels:

• Finasteride: An oral medication that blocks the enzyme responsible for converting testosterone into DHT. It halts hair loss in over 80% of men and can promote regrowth.
• Minoxidil: A topical solution that acts as a vasodilator, increasing blood flow and nutrient delivery to the hair follicles, stimulating the growth phase.

Consistency is key. Hair operates on a long growth cycle, so it typically takes 3 to 6 months to see visible results.
