What is finasteride, and how does it treat hair loss?

Here’s a straightforward explanation of finasteride and how it works for hair loss:

• What It Is: Finasteride is an oral prescription medication approved by the FDA to treat hair loss, specifically androgenetic alopecia (male pattern baldness).
• How It Works:
  • Blocks the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT).
  • Reduces DHT levels, which helps prevent hair follicles from shrinking.
• Slows Hair Loss: It effectively slows or stops hair loss in most men with consistent use.
• Promotes Regrowth: In some cases, finasteride can also stimulate regrowth of hair in thinning areas.
• Best for Specific Areas: Works best for hair loss at the crown and mid-scalp areas.
• Takes Time: Results usually become noticeable after 3-6 months of daily use, with optimal results around 12 months.
• Requires Consistency: Stopping finasteride may reverse its effects and lead to resumed hair loss.
• Side Effects: Rare side effects include decreased libido, erectile dysfunction, or mood changes. Always discuss these with your doctor.

Finasteride is most effective when used under the supervision of a healthcare professional. It’s often combined with other treatments like minoxidil for enhanced results.
