How does finasteride work for hair loss?

I've been noticing significant hair thinning lately, and my dermatologist suggested 'Finasteride'. Before I start, I want to understand what it does. How exactly does this medication work to stop hair loss?

My dermatologist explained that finasteride works by blocking an enzyme called 5-alpha reductase, which converts testosterone into DHT. Since DHT is what shrinks hair follicles in male pattern baldness, blocking it helps stop hair fall and can even cause some regrowth. It takes about 3 to 6 months of daily use to see real results.

It basically reduces the hormones that cause your hair to thin out and fall. Many people use it successfully, but please make sure to discuss it with a doctor first to see if it is suitable for you.

I manage my high BP with lifestyle changes, and when I asked about hair loss treatments, my doctor said everything is interconnected. Finasteride affects hormones, so you need to be in good overall health before starting it. Make sure you get your routine health checks done regularly.

Before you buy this medicine, calculate the long-term cost because you have to take it continuously to maintain the hair. Also, budget for the initial dermatologist consult and periodic blood tests to monitor your hormone levels. It is a commitment, so plan your expenses accordingly.

I heard that it stops the hormone DHT from attacking our hair roots, but I am really worried about the potential side effects I read online. Has anyone here used it long-term without experiencing any mood swings or other issues?

My doctor at Apollo Specialty Hospital prescribed this to me after checking my scalp condition. It alters your hormone levels to stop hair thinning, so you should never take it without a proper prescription and guidance. Ask your doctor clearly about the dosage and any precautions you need to take.
