Hair Grafting Procedure:


Before the surgery, the ‘donor area’ is trimmed short to allow easy access and removal of the grafts.

In a punch-graft, a special tube-like instrument made of sharp carbon steel punches the round graft out of the donor site to be replaced in the area to be covered i.e. normally the frontal hairline. In other grafting techniques, a scalpel is used to remove small sections of hair-bearing scalps and divided into small sections for transplantation in tiny holes or slits in the scalp.


The donor site holes may be closed with stitches-for punch grafts where a single stitch may close each punch site. A straight line scar is the resultant of the other grafting techniques. All stitches are usually concealed with the surrounding hair.


Small amounts of saline are periodically injected into the scalp to maintain proper skin strength when grafts are taken and to maintain healthy circulation in the scalp, the grafts are placed about one-eighth of an inch apart. The spaces between the plug are filled in with additional grafts in later sessions. The average numbers of large plugs transplanted in the first session are around 50, though it may vary with each individual. In mini-grafts or micro-grafts, the numbers can go up to 700 per session.


Great care is to be taken while removing and placing grafts to ensure that the transplanted hair will grow in a natural direction and that hair growth at the donor site is not adversely affected.
On completion of the grafting session, the scalp is to be cleansed and covered with gauze and the patient may be required to wear a pressure bandage for a couple of days. Some surgeries allow a bandage-free recovery.
To achieve satisfactory results, one may normally need several surgical sessions with a healing interval of several months between each session. In most cases, it takes up to two years before the final result of the full transplant series is visible.


The amount of hair coverage after hair grafting depends partly on the existing colour and texture of the patient’s hair. Coarse and grey or light-coloured hair has a better coverage than fine and dark-coloured hair. 

Tissue-expansion technique


The leaders in the tissue-expansion technique are the plastic surgeons as this a technique commonly used in reconstructive surgeries to heal fix burn wounds and injuries with major loss of skin.

 

  • Application of tissue-expansion in hair replacement surgery has yielded striking results with significant coverage in a relatively short amount of time.
  •  In this technique, a tissue expander which is a balloon like device is inserted beneath the hair bearing scalp that lies next to a bald area. The device is gradually inflated with salt water over a period of several weeks leading to the skin being expanded to grow new skin cells and causing a bulge beneath the hair-bearing scalp.
  • When the skin beneath the hair has stretched enough-usually about two months after the first operation-another procedure is performed to bring the expanded skin over to cover the adjacent bald area
