By the age of 50, about 50% of men and a substantial number of women are affected by hair loss, much of which is hereditary.
Flap surgery used to be done at the past and is performed in a surgical setting. FUE (Follicular Unit Extraction) is done under topical anesthesia, has no scars but requires more time and sessions. It requires hundreds of micro-grafts, each of which will generally contain 1-3 hairs mini grafted from a donor site on the back or the sides of the head. Micro-hair transplantation (FIT or Follicular Isolation Tecnique) uses also topical anesthesia in an outpatient basis.The donor site leaves a thin scar 1mm of width. It will be conspicious only when shaving the hair and even then we can make a medical tattoo to remove it.
The grafts will be randomly implanted in the bald or "thinning area" of the head. 1-1.5 months after, the transplanted hair will fall out. They will be replaced 3-6 months after when the new hair grows in. To achieve sufficient density, 2 or more sessions may be required. Stem cells and PRP (platelet rich plasma) treatments can be used for optimization of the hair transplantation process. The PRP is also the most promising treatment at the alopecia areata.
