Cosmetic methods providing a significant improvement over existing hair transplantation methods by providing greater hair density per hair implant, which is achieved through the process of an enhanced hair multiplication in vivo (e.g. in the scalp of a subject). The cosmetic methods also provide improved aesthetic results, particularly, more realistic and natural looking results, relative to the results obtained by traditional methods. The cosmetic methods are particularly suitable for hair transplantation in recipient areas of a subject experiencing baldness or lack of hair, optionally due to Androgenic alopecia, burn injuries, cancer chemotherapy, or other genetic or environmental factors or scarring.
