Primarily two techniques are used for hair transplantation - the strip harvesting technique and the follicular unit extraction (FUE) technique. Strip harvesting leaves a thin linear scar in the donor area. The surgeon harvests a strip of skin from the posterior scalp where hair growth is good. A strip of size about 1 to 1.5 x 15 to 30 cm is surgically removed which leaves a scar. The scars are generally covered later by a patient's hair.
In the follicular unit extraction (FUE) technique, tiny punches of a size typically between 0.6 mm and 1.0 mm in diameter are made. In such cases, there is no linear incision on the back of the head and it doesn't leave a linear scar. However, it requires increased surgical times and higher cost to the patient.
The transplanted hair appear just like normal hair, shampoo and oil can be applied and can be combed in any style of one's choice. They never fall and grow normally at a rate of 1-2 cm per month like other hair.
There is no hereditical effects of the hair transplantations on the next generation.
