Read more →Male pattern hair loss (androgenetic alopecia) is largely driven by genetics and the effect of the hormone DHT on hair follicles over time. It is progressive, which is why many people explore treatment earlier rather than later. A clinician can help identify the pattern and cause.
Commonly discussed options include finasteride, dutasteride, and minoxidil (topical or oral), sometimes in combination. Whether any option is appropriate for you is a clinical decision made by an independent licensed clinician after an evaluation. This page does not recommend a specific treatment.
They work differently: finasteride is an oral medication that reduces DHT, while minoxidil is applied topically (or taken orally) and is thought to prolong the growth phase of hair. Some people use them together under clinical guidance. Your clinician can explain the trade-offs for your situation.
