Criteria For Determination Of Ability To Transplant

To determine the feasibility of a body hair transplant, true uses the torso donor index. In order to evaluate the properties of the donor zone, for a transplant of body hair, this tdi is established according to five criteria:

A density greater than 40 uf per cm²;

The similarity of hair and hair;

The number of 2 and / or 3 hair follicles (uf);

The size of the donor area;

The length of body hair. 

If the index of the donor zone, therefore, body hair, is less than or equal to 4, a transplant of body hair is not indicated for the patient. Patients with a of 5, 6 or 7 may at the most / subject to undergo Hair Transplant In Karachi patients with a value equal to or greater than 8 have more hair than hair qualified donor material, and can ideally lend themselves. 

Differences Between A Fue-Bht And A Classic Fue:

The technique of body hair transplantation is derived from the fue technique; the donor zone is then extended to the entire body and is no longer limited to the hair alone. Bht is mainly used when the donor area of ​​the scalp can no longer supply donor material or has a particularly low density. 

In these cases, and if the body has adequate properties, the follicular units can be directly removed from different body areas, such as the torso, arms or legs, and transplanted into the scalp. Fue-bht opens up new opportunities, especially for patients whose donor areas have been misused or damaged by outdated techniques. 

Patients eligible for bht must provide good physiological predispositions; this is how the body hair is good to serve as hair. Body hair goes through other phases of growth than hair  it is not yet scientifically proven that this changes over time, but experiences suggest that this may indeed be the case. Fue taken from the body are distinguished from the hair by their anatomy: while follicular hair units are composed of 1, 2 or 3 hair, body hair usually only includes one hair per unit. 

The following example shows the differences in the donor material, depending on whether it is hair or hair: 60 fue per cm² of hair give a hair density of 60 to 70 hairs per cm², while 60 fue per cm² of hair give a density of 90 to 120 hairs per cm². It is thus clear that in order to obtain a natural-looking capillary density, practically twice as many body implants as capillary grafts are required. This is also the reason why a bht is used rather to density the hair and not when the present hair can serve as a donor material.
