Used primarily in the treatment of benign prostatic hyperplasia (BPH), it helps reduce the size of an enlarged prostate, alleviating symptoms such as difficulty in urination. Additionally, it is employed in the management of male pattern hair loss by inhibiting the conversion of testosterone to dihydrotestosterone (DHT), which is responsible for hair follicle shrinkage. Its application in reducing DHT levels also makes it a subject of interest in studies related to prostate cancer prevention, though it is not officially approved for this use.
