■ Once cloned hair was shed in the normal hair cycle, it did not follow this cycle and regrow ■ There are no published studies to prove that hair cloning would work in humans. a significant technical problem to hair cloning in humans is that the cells in culture lose the ability to produce new hair, which appears to be the single greatest obstacle to this form of therapy. Unfortunately, there are also no published studies to prove that follicular cell implantation would work in humans.
Surgical treatment of baldness surgical procedures are currently used daily to provide a definitive aesthetic correction of alopecia. all the methods described in this article are not only for the treatment of male and female pattern baldness, but also for alopecia caused by traumatic injury, second and third degree burns, post-radiotherapy for brain tumour, african–american traction alopecia, post-lifting scars, eyebrows, eyelashes, beard, moustache and pubis. The choice of follicular unit transplantation technique
will depend on the degree and location of the alopecia, as well as the age and ethnic considerations of the patient. Most hair transplant procedures are performed on an
outpatient basis, using local anaesthesia (anaesthetising cream and nerve blocks). Follicular unit micrografting is a procedure during which 1000–4000 hairs are redistributed into the thinning or balding areas. Once harvested from the ‘donor’ area (Figure 6), hair
follicles are microscopically dissected into ‘grafts’ (FUL) or extracted with a hand or a power micropunch (FUe). each micrograft contains a single ‘follicular unit’ consisting of between one and four hair follicles. FUe or FUL are then carefully implanted into the bald or thinning ‘recipient’ area. Meticulous artistic and technical skill is required to design an appropriate hairline, as well as ensure the appropriate angle, orientation and position of each transplanted hair. FUL or FUe create a result that defies detection and is never ‘pluggy’. The hair transplant session is usually completed in approximately 2–5 hours. The almost painless surgery and simple postoperative
care allows few discomforts for the patient. some itching and swelling can occur, but this is generally mild. Normal physical activities can be resumed immediately and the first shampoo 1 day after the procedure. crusting and scabbing of the transplanted areas are hidden by the long hair and last for approximately 10–12 days. The transplanted hair falls out in 2 weeks and generally begins to grow after 3 months. Transplanted hair lives and grows indefinitely. The hair can be styled in any way the person desires.
The techniques Follicular unit long hair technique it has been many years since the author developed the follicular unit long hair (FUL) technique (20) (Figure 7). hairs are not shaved like in the conventional FUT technique, but the progress is almost the same. For the patient, the advantages of this procedure are numerous.

The ‘wait and see’ is replaced by the ‘see and wait’ — the patient will see the result immediately, although most of the transplanted hairs have the transient loss 2–3 weeks later (the use of minoxidil lotion and finasteride can decrease this hair-loss). Furthermore, the donor area is not shaved and patient scabs of the recipient area are hidden by the long hair. For the surgeon, the benefits of this procedure include
a better evaluation of the orientation and the obliquity of transplanted hairs; a better choice for the refinements of the frontal hairline with thinner or lighter hairs; and a greater amount of hair can be transplanted during one treatment session. in the author’s opinion, the only disadvantage is for the patients who routinely shave their scalp.
