Hair replacement

The surgery

There are many hair transplant methods and usually a technique combination is used.
Hair transplant is done under intravenous sedation combined with local anesthesia. During surgery you will be awake but relaxed. General anesthesia may be used when tissue expansion or rotating flaps are used.
The hair transplant surgery involves the harvest of hair grafts with roots from the donator region, usually occipital or temporal. Then they are braked up under the microscope and are implanted in the receptor region. Depending on their size there are more types of grafts: micro grafts (1-2 hairs), mini grafts (2-4 hairs) and big circular or longitudinal grafts (10-40 hairs). The last ones usually have an unnatural look and this is why they are not used any more. During one operation session the number of micro and mini grafts that can be transplanted ranges from 700 to 1000. To maintain a normal blood flow in the scalp region, the grafts must not be to close to each other. The spaces between them are filled in another surgery.
Tissue expansion usually used in reconstructive surgery has also found its use in baldness treatment. It achieves significant coverage in a short period of time. The procedure consists in the insertion of a tissue expander under the hairy skin. The skin surface is stretched with the gradual flow of the expander.
