What is the lowest donor density a person can have in their late twenties, in order to have a successful transplant?
There is no simple answer to this question on donor density. First, I would want to make sure that the person should not have Diffuse Unpatterned Alopecia, which would reflect a depletee donor area in a young man (1-2% of the male population). Then, the size of the balding area (the area of the demand) and the eventual pattern of balding that would have to be maintained must be balanced in a well defined master plan with a worse case scenario put together. A good doctor can make a judgment on the value of the donor density.
