"Hi, I have a small bald patch in my mustache which really affects me psychologically. I try to cover it up with kajal, but most of the time, I end up with smudges. This patch appeared a few years ago when I traveled on a bus and had a small injury and infection. Pus formed, and after it healed, hair stopped growing in that area. Please give me solutions. Do I need to get a hair transplant in that small area? If the hair follicles are damaged, can it still be done? If the transplant doesn't work, are there any other options?"
