Some of the important factors that make an individual a good candidate for surgery are as follows: The overall quality and abundance of existing hair is paramount. (Along with texture, color and curl). Age of perspective patient - The older you are, the more recognizable your hair loss pattern will be. (It is very normal to be turned down by a hair transplant physician when you are in your twenties due to this factor.) Patient expectation - Do you realize that you will not gain one additional hair? Hair transplantation involves relocating hairs you already have.
