Hair transplantation

Hair transplantation is a surgical technique that involves moving individual hair follicles from one part of the body (the donor site) to bald or balding parts (the recipient site). It is primarily used to treat male pattern baldness, whereby grafts containing hair follicles that are genetically resistant to balding are transplanted to bald scalp. However, it is also used to restore eyelashes, eyebrows, beard hair, chest hair, and pubic hair and to fill in scars caused by accidents or surgery such as face-lifts and previous hair transplants. Hair transplantation differs from skin grafting in that grafts contain almost all of the epidermis and dermis surrounding the hair follicle, and many tiny grafts are transplanted rather than a single strip of skin.

Since hair naturally grows in follicles that contain groupings of 1 to 4 hairs, today’s most advanced techniques transplant these naturally occurring 1–4 hair "follicular units" in their natural groupings. Thus modern hair transplantation can achieve a natural appearance by mimicking nature hair for hair. This hair transplant procedure is called Follicular Unit Transplantation (FUT). Donor hair can be harvested in two very different ways;

1. Strip Harvesting - a strip of scalp is removed under local anesthesia, the wound is then sutured back together and this piece of scalp tissue is then cut in to small pieces of tissue called grafts which are then transplanted back in to the thinning area of the patients head. This method will leave a linear scar in the donor area, which should be covered by a patients hair (if long). The recovery period is around 2 weeks and will require the stitches to be removed by medical personnel.

2. Follicular Unit Extraction or FUE Harvesting - individual follicles of hair are removed under local anesthesia; this micro removal uses tiny punches of between 0.6mm and 1.25mm in diameter. Each follicle is then reinserted back in to the scalp in the thinning area using a micro blade. Because this is single follicles and no large amount of tissue is removed there is no visible scars or post-surgery pain, with no stitches to be removed. Recovery from FUE is within 7 days.
