Erythema Centrifugum: The Unexpected Hidden Cause

A 19-year-old with diffuse hair thinning and erectile dysfunction is considering starting Propecia (finasteride) while already using a minoxidil solution with anti-androgens. Concerns are raised about the psychological nature of erectile dysfunction and the potential systemic effects of anti-androgens, with suggestions to address porn addiction and consult a doctor about hormone therapy.

Finasteride is effective for treating male pattern baldness (MPB) with minimal side effects, and topical finasteride is similarly effective. Dutasteride is also effective but less understood, and Minoxidil is less effective than Finasteride.

Finasteride may affect prostate sensation and size, with some users reporting easier urination. Concerns exist about prostate shrinkage even at lower doses.

Finasteride is recommended for hair loss treatment, with potential side effects like erectile issues in 1 in 33 users, which typically resolve after stopping the drug. Users report mixed experiences, with some experiencing initial side effects like brain fog and others seeing no issues, and the drug is generally considered effective for maintaining or regrowing hair.

The user experienced successful hair regrowth with Finasteride and Minoxidil but developed erectile dysfunction and abdominal pain, possibly due to medication or lifestyle changes. They plan to consult a urologist and consider adjusting medication or trying supplements like zinc, DIM, or boron.

Finasteride's effectiveness and side effects may vary based on male phenotypes, with some users noting differences in response related to body and facial hair characteristics. Some users report success with lower doses, while others experience side effects, suggesting individual variability in response to the treatment.
