Stop the Loss at the Source

Finasteride

Finasteride is a 5-alpha reductase inhibitor that blocks the conversion of testosterone to DHT — the androgen responsible for the miniaturization of scalp follicles in male pattern hair loss. It's the single most effective oral medication for stopping hair loss and is the foundation of any serious hair-loss protocol.

How it works

The mechanism

By inhibiting 5-alpha reductase, finasteride lowers scalp DHT by ~60%. Dormant follicles can recover and existing hairs are protected from further miniaturization. Used long-term, it stops the underlying hair-loss process.

Who it's for

Best candidates

  • Men with male pattern hair loss at any stage
  • Patients combining oral with PRP and topical minoxidil

Protocol

1 mg orally once daily. Bloodwork at baseline and 6 months. Long-term use is the norm — stopping reverses results within months.

Timeline

Reduced shedding in 3 months. Visible regrowth at 6–12 months. Full benefit by 18 months.

What to expect

Side effects & considerations

Possible reduced libido or erectile changes (low single-digit %, usually reversible). Topical finasteride is an option for men concerned about systemic exposure.
