Any surgical procedure will create some degree of scarring, some more visible than others, dependent on the area and in the case of a hair transplant how short the hair is worn.
The 2 recognised hair transplant techniques are FUE and FUT; they differ in the manner the hair is extracted from the sides and back of the scalp, known as the donor area. FUE relies on a cylindrical punch surrounding an individual FU, making a punch incision and then the graft is removed, normally manually with forceps, the punch diameter ranges from around .75mm to 1.1mm. The punch marks left heal over a couple of weeks, the scarring generally shrinks and can leave small white dots over the surface of the donor area.
FUT relies on the follicular units being removed in a single strip of hair bearing tissue, the line is sutured or stapled and they are generally removed around 10 days post operation. FUT or Strip surgery leaves a fine linear line normally around 2mm´s around the donor area; with the latest closure techniques hair grows back through this line to break it up and camouflage it further.
With either technique it is easy to hide the scarring with minimal hair length, but too short a hair style and it can become visible. This is important to understand that regardless of technique some degree of scarring remains, albeit relatively minor. Each technique has pros and cons and it important to understand why one maybe the better option over the other. Correct donor management is important to ensure the most FU´s can be removed safely and with minimum change to the area.
