The donor area in the average Caucasian male has ~12,500 Follicular Units ?of which possibly up to 60% can be taken for hair transplants. Fur FUE without seeing over-harvesting, about half of this amount (30% or 3,750) can be taken with FUE to be safe. The thickness of the hair shaft (fine, medium or coarse) alter this number (lowers if for fine hair and increases it for coarse hair).
