Price Discrimination Across Indications in the Pharmaceutical Industry: The Case of Finasteride

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.

A 40-year-old man experiencing male pattern baldness reports noticeable hair regrowth after 6 weeks of using finasteride 1 mg daily, topical minoxidil 5% twice a day, and ketoconazole shampoo twice a week. He has not experienced any side effects and plans to continue monitoring his progress.

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.

A 25-year-old male experienced significant hair loss due to telogen effluvium and androgenetic alopecia. He began using finasteride, minoxidil, and vitamins, seeing some regrowth but remains worried about hair density.

A 25-year-old male experienced significant hair regrowth after one year of using 0.5mg daily finasteride, with plans to add 1.25mg oral minoxidil and microneedling for further improvement. He also uses Nizoral shampoo weekly and reports no current side effects.

A 21-year-old male diagnosed with telogen effluvium and male pattern baldness started oral finasteride, which initially slowed hair loss and slightly thickened hair, but experienced increased shedding after surgery. The doctor recommended iron and vitamin D supplements, and the user is seeking additional advice.
