The process involving follicular hair transplants is considered to be the most effective among hair restoration methods. In follicular hair transplant, the surgeon transplants hair from the permanent zone in the back of the scalp onto the affected areas. The donor tissue is removed in one piece. This is to ensure that the follicular units being relocated from the back of the scalp are not damaged. An integral part of hair follicle transplant is single-strip harvesting as it preserves the follicular units. It also ensures that no damage is caused to the individual hair follicles.
Follicular hair transplants technique follows a well laid out pattern. Follicular hair transplants allow the surgeon to use small recipient site. During the surgery the follicular units that are removed from the donor tissue are minutely studied by a microscope. This stereomicroscopic dissection raises the yield of the absolute number of follicular units, and that of the total amount of hair as well. During follicular hair transplant the surgeon scans - under a microscope - the follicular units to be removed from the donor tissue. This stereomicroscopic dissection helps in protecting the follicular units. It also ensures a rich yield of both the follicular units and the total amount of hair that is restored.
In follicular hair transplants the donor strip is the hair strip that is taken from one part of the body and transplanted to the bald region of the scalp. In this technique the donor tissue is removed in one piece. This ensures that the follicular units being removed from the back of the scalp do not suffer from any damage. Follicular units are a bundle of hair growing together. A follicular unit is usually formed of one to four terminal hairs. Every follicular unit is surrounded by one to two fine vellus hair, oil glands, a small muscle and a fine band of collagen. The follicular unit is the skin's hair-bearing structure ensuring maximum growth. It looks like a well-formed structure under the microscope.
If you need a large area covered, then you most likely want to go for follicular hair transplants because it is the more economical in terms of number of grafts for price paid. If you absolutely, positively don't want strip surgery as you are worried about scarring, then hair is your only alternative. Contrary to popular belief, both methods leave scars. follicular hair transplants will leave a narrow line across the back of your head, whereas hair will leave little unpigmented dots across the back of your head. The only difference is that the hair scars are not concentrated together and therefore harder to detect when wearing hair very short.
