Are there any medicines or supplements for severe hair loss in the front area of the head?

Patient: I need to find a way to increase the hair in the front area of my head (from the frontal and parietal areas of the scalp) , I’ve lost a lot of hair and I’ve been to a dermatologist but the medicines didn’t work ,it has nothing to do with genetics and I don’t want to transplant hair . Is there anyway to go back to normal ,are there any vitamins,supplements,or medicines I should take to increase hair ?thank you so much
