In 1939 the Japanese dermatologist described the punch technique for the first time. This technique, however, produced unnatural and bushy results. Until its further development in 1960, the punch technique was only used on burn victims.
In 1986 the physician Manfred Lucas from Munich introduced in London minigrafts and micrografts, a coverage treatment, which involves removing a strip of tissue from the hair wreath, dividing it into small and medium-sized hair pieces and inserting them in the areas where needed.
In 1990 minigraft and/or micrograft technique was further developed into the FUT (Follicular Unıt) technique. It also involves removing a strip of tissue from the hair wreath , only that in this technique a high-resolution microscope is applied, which dissects natural bunches of hair. The disadvantage is that scars are visible.
The most up-to-date method nowadays is FUE (Follicular Unit Extraction). Hair follicles are individually extracted with a hollow needle from the hair wreath and implanted in areas where needed. This involves tiny incisions with specially manufactured blades of 0,6-1,5 mm in width. The subsequent insertion of the follicles is performed using a tweezer. In the implantation process, the right hair angle has to be taken into consideration and a hair density that is compatible with the recipient site has to be chosen. Advantages of this method are, that besides its effectiveness, no scars are left.
