How Does Finasteride Work?|Article Discussion|Forum|SNES HUB

finasteride 1mg is a 5-alpha-reductase inhibitor, which means it blocks the enzyme responsible for converting testosterone into dihydrotestosterone (DHT).

• DHT and Hair Loss: DHT is a hormone that contributes to hair follicle shrinkage, leading to hair thinning and eventual hair loss in androgenetic alopecia. By reducing DHT levels, finasteride helps slow hair loss and can even promote regrowth.
• DHT and Prostate Health: In BPH, high DHT levels cause the prostate to enlarge. Finasteride reduces prostate size, alleviating urinary symptoms.

Uses of Finasteride

1. Androgenetic Alopecia:
   • Approved for men with mild to moderate hair loss.
   • Taken as a 1 mg daily dose for hair regrowth and to prevent further loss.
2. Benign Prostatic Hyperplasia:
   • A 5 mg dose is typically used to treat symptoms like difficulty urinating or frequent nighttime urination.

Benefits of Finasteride

• Clinically proven to slow or stop hair loss in 85% of men using it regularly.
• Helps regrow hair in about 65% of users over extended periods.
• Reduces the risk of prostate surgery or complications in men with BPH.

Potential Side Effects

While effective, finasteride can have side effects, including:

• Decreased libido or sexual function in a small percentage of users.
• Breast tenderness or swelling (rare).
• Mood changes or depression (in very rare cases).

These side effects are generally reversible upon discontinuation of the medication.
