Hello Doctor, I’ve been dealing with alopecia for the past 3–4 years. There is a patchy area on my scalp where the hair hasn’t grown back, and I’m now seriously looking for treatment options. I would like to know what effective treatments are available to help regrow hair in that specific area. I’m also curious about the causes, whether it’s permanent, and if any tests are needed. Please suggest the best course of action, including any medications, procedures, or lifestyle changes that could help. I’m really hoping to restore hair growth in that affected area. Thank you.
