DHT blockers are medications used to treat Androgenetic Alopecia by reducing levels of dihydrotestosterone (DHT), a hormone responsible for hair follicle shrinkage. Common options include Finasteride and Dutasteride, which inhibit the enzyme that converts testosterone into DHT. By lowering DHT levels, these medications help slow hair loss and may promote regrowth over time. They are typically used under medical supervision, as results vary and long-term use is often required to maintain benefits and prevent further progression of hair thinning.
