Techniques
Modern hair transplant surgery uses two main techniques:
Strip Harvesting
A 6 to 8 mm wide strip of donor skin from the back of the scalp is removed and transplanted to required areas with an instrument specifically designed for this purpose. This method is fast, simple and very accurate.
The instruments allow for the simultaneous harvesting of two or three or more donor strips. The strips are removed from an area at the back and the sides of the scalp, because hair from these areas is permanent. In addition to increasing the yield of donor grafts, strip harvesting also provides an excellent cosmetic appearance to the donor area as the incision is closed to a virtually imperceptible line.
Follicular Transplantation (mini- and micrografts)
Minigrafts (2 to 3 hair roots) and micrografts (1 hair root) are extremely small grafts of hair that have several advantages:
- rapid healing
- less visible scarring than the older plug method
- a high success of acceptance by the recipient site
By blending combinations of mini and micrografts into the recipient site an excellent natural appearance can be created. The miniature grafts are prepared using a magnification lamp or microscope and precision blades to excise 1 to 3 hairs at a time from the previously removed donor strip. The follicular units are then implanted into stab incisions that measure 1-3 mm, which have been prepared in the thinning or bald areas at the front or crown of the scalp. No existing hair is removed with this implantation technique.
