Hair transplantation can be quite time intensive. Depending on the amount of hair that needs to be transplanted, it often takes several operative sessions, and these must be placed at least 6 to 8 months apart. We can move hair in very thin strips or we can use plugs containing 10 or 15 hairs per plug, but these techniques are much less popular than they once were. They often produce an artificial look that can be detected by others on casual inspection. Now it is more common to do much smaller unit transplants.
In other words, we may transplant single hair follicles or small groups such as 2 or 3 hair follicles in a single group and it is not uncommon to transfer between 750 and 1,500 hair follicles at a single session.
Some surgeons are able to transfer up to 2000 or even more follicles in a single session. When one transplants hair, it is quite common for the hair shaft in that follicle to fall out. The transplanted hair follicles often go into a resting phase before they begin to produce new hair. It often takes up to a year following the hair transplantation to see the full result of the procedure. If necessary, one can then go back and provide more individually placed hair transplants to fill the small gaps that exist after the initial procedure. Technically, during the procedure, if one attempts to place the graft too close to the one just previously placed, the first graft begins to pop out as one attempts to insert the second. One usually has to place the grafts about 1/8 inch apart. This is not as dense as normal hair so it is often necessary to go back 8 months to a year later and place more follicles between those originally transplanted.
It is estimated that perhaps 20 percent of women will experience some degree of hair loss. It can be related to some underlying illness or perhaps due to hormonal change after menopause. Usually, it is a general thinning of hair rather than losing hair over a specific patch such as is more common in men. Although hair transplantation is less commonly done in females, there is certainly no reason why you could not consider transplantation if there is enough donor hair. Sometimes, you can make the hair loss worse if you constantly pick at a spot where you are losing hair, so you should try to be careful about this.
