Hair transplants

Faced with hair loss or thinning hair, some people decide on hair transplants as a way to regain a fuller head or hair.

Hair transplants are considered cosmetic procedures and are not available on the NHS.

Hair transplants are not without risks, and should be considered after trying other treatments and after seeking medical advice.

Hair transplants can be expensive and are carried out over a series of sessions.

What is a hair transplant?

First performed in the 1950s, and widely available in the UK at private clinics, hair transplantation is surgery that involves removing a narrow strip of hair-bearing scalp from the back of the head and using it to fill an area with thin or no hair.

Most hair transplants are performed under local anaesthesia. To transplant hair, the surgeon first cleans the scalp, then injects an anaesthetic to numb the area where a strip of scalp will be removed. After removing the strip of scalp with a scalpel, the surgeon sets it aside and sews the scalp closed. This area is immediately hidden by the hair around it.

Next, the surgeon divides the strip of scalp removed into approximately 500 to 2,000 tiny grafts containing an individual hair or just a few hairs each. The number and type of graft used depends on the hair type, quality and colour, as well as the size of the area where it will be transplanted to.

After the grafts are prepared, the surgeon cleans and numbs the area where the hair will be placed, creates holes or slits with a scalpel or needle, and delicately places each graft in one of the holes.

Depending on the extent of the procedure, the transplant will take approximately four to eight hours. Sometimes additional sessions are needed if you continue to lose hair or decide that you want thicker hair.

Expectations and recovery

After hair transplant surgery your scalp may be very tender. You may need to take pain medications for several days. Your surgeon will instruct you to wear a surgical dressing over the scalp for at least a day or two. Your surgeon may also prescribe an antibiotic and/or anti-inflammatory drug to be taken for several days following surgery. Most people are able to return to work two to five days after surgery.

Within two or three weeks after surgery, the transplanted hair will fall out, but you should start to notice new growth within a few months. Most people will have attained 60% of new hair growth after six to nine months. Some surgeons prescribe the hair-growth drug minoxidil to improve hair growth following transplantation, but it is not known how effective this is.
