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.
The transferred tissue is not “rejected” as it is not a foreign tissue. The transplanted hair maintains its own characteristics; colour, texture, growth rate, and curl, after transplantation and regrowth. The vitality of the grafted follicle is maintained by the rich blood supply to the scalp. Originally many years ago, large circular grafts (commonly called ‘plugs’) containing 15-20 hairs were transplanted resulting in noticeably unnatural results. Over years, instruments and techniques have been developed that allow hair transplant surgeons to achieve truly natural results by transplanting large numbers of small grafts very close together. We have found that hair grows from the scalp in groups of one, two, or three (and rarely, four) hair follicles, called “follicular units.” We can transfer these groups of follicles, called “follicular unit grafts,” after eliminating the excess surrounding tissue
This allows the grafts to be placed closer together resulting in a denser and more natural result. A significant amount of artistry is also needed in order to recreate the natural patterns of hair growth.
