Finasteride Guide

Finasteride is one of the most clinically proven treatments for male pattern baldness.
It’s not hype — multiple studies confirm its ability to slow hair loss and regrow hair for most men.
But it’s also a prescription medication that requires awareness of potential side effects and proper use.

1. What Is Finasteride?

• Generic Name: Finasteride
• Brand Names: Propecia (1 mg for hair loss), Proscar (5 mg for prostate issues)
• Type: Oral prescription medication
• Approved Use for Hair Loss: Male pattern baldness (androgenetic alopecia)

2. How Finasteride Works

• Blocks the enzyme 5-alpha reductase
• Reduces DHT (dihydrotestosterone) — the hormone that shrinks hair follicles in genetically prone men
• Slows miniaturization of hair follicles and can promote regrowth in thinning areas

Fact: In a 5-year clinical study, 90% of men taking finasteride maintained or increased hair count, compared to 25% on placebo.

3. Who Should Consider Finasteride?

• Men aged 18–65 with early to moderate male pattern hair loss
• Men who want a long-term treatment (results require ongoing use)
• Not recommended for women or children

Best Candidates: Men noticing thinning at the crown, receding hairline, or overall density loss in the last 1–5 years.

4. How to Take Finasteride

• Standard Dose: 1 mg daily (with or without food)
• Time to See Results: 3–6 months for shedding to slow; 6–12 months for visible regrowth
• Ongoing Use: Continuous — stopping can reverse gains within 6–12 months

5. Possible Side Effects

Important: Most side effects resolve after discontinuation. Discuss risks with your doctor before starting.

6. Safety Considerations

• Pregnancy Warning: Women who are pregnant or may become pregnant should not handle crushed/broken tablets (risk to male fetus).
• Inform your doctor if you have liver issues before starting.
• Routine blood work isn’t usually required, but some providers monitor PSA (prostate-specific antigen) levels.

7. Combining Finasteride with Other Treatments

• Minoxidil (topical or oral) — works via a different mechanism; pairing often boosts results
• Microneedling — can improve topical minoxidil absorption
• Low-Level Laser Therapy (LLLT) — adds non-drug stimulation for follicles

8. Realistic Expectations

• Works best for slowing or stopping loss — regrowth is possible but varies by individual
• Earlier use = better results
• Requires commitment — stopping will return hair to baseline loss progression

9. Cost Overview

• Generic Finasteride: $5–$25/month depending on pharmacy and country
• Brand Propecia: $60–$80+/month
• Online hair loss clinics may bundle with consultations for convenience

Bottom Line:
Finasteride is a gold-standard treatment for male pattern baldness, but it’s a medical decision — not a casual grooming purchase.
Used correctly, it can significantly slow hair loss and help regrow hair, especially when started early and combined with complementary treatments.
