Ability to grow the transplanted hair depended on from where the graft was taken and not the site where it was grafted Follicular unit transplantation respects the way in which hair normally grows in the scalp. Aesthetic results appear so natural to the naked eye even upon close examination and one cannot make out that a procedure is done.
In Hair Transplantation no new hair is grown. It is readjustment of the existing hairs in the scalp.
In FUT a strip of Scalp with the hair from the back is harvested first and Trichophytic suturing of the donor area is done to grow the hair through the scar to reduce the donor site deformity. The strip is first reduced into thin slivers containing single row of hairs and then each follicular unit is prepared under Video microscope having backlight and cooling source. Each unit may contain 1, 2. 3 or even 4 hairs. Prepared follicular units are implanted by one of the following methods
1. Punch holes 18G needles and implanted
2. Stick and Pack using (Follipen) a special device to avoid damage to the hair
These hairs are handled gently and kept in ice cold saline till it is implanted. Thus there is absolutely no damage to the hairs during any of these procedures..
FUE is the latest technique in harvesting the follicular units and is not done in many centres. It is fast catching up among Hair transplant Surgeons. The advantage is there is no incision or sutures in the donor area, spotting short hair style is possible and donor site heals well within short period. The follicles are harvested either using a manual punch or a sophisticated motorised extractor.
The entire surgery is done under Local anaesthesia as a day care procedure. It is painless and oral medications are only for 4 days. So there is no need for Hospitalisation and the patient can go home soon after the procedure
