How Hard To Extract Grafts With FUE

FUE, follicular unit extraction, is a blind hair transplant extraction method; meaning that as the punch enters the skin it is not possible to see the follicular unit depth or direction

Understanding the direction of the hair as it exits the skin is vital, as is depth control of the punch; as it is impossible to see with the eye so a great understanding of anatomy is required

Regardless of manual or motorised punch tools due care must be taken as any damage caused during the extraction process needs to be kept to a minimum, with around a 5% transection rate; if the transection rate gets too high then a decision has to be made whether the process should be continued

The depth the FU sits in the scalp can also alter, some more shallow or deeper than other; in general most individuals there is a small variant in depth around the head but in some cases the depth can alter dramatically, even in the same areas, making depth control of the punch harder to be consistent

If depth control is not managed correctly it can impair the quality of the graft being removed and potentially create more visible scarring with the post operation healing

The angle of the hair will alter dependent on the area of the scalp it is position in, the sides and back of the head; when punching the FU´s the positioning of the hand and body needs to change to compensate for the changes in direction; generally the sides being more acute and the back the hairs facing down

The direction of the hair as it exits the scalp can differ from how the follicle is directed under the skin; if this is not understood it can lead transecting the follicular unit, best case scenario is the FU is split and the healthy hair count reduced, worst case scenario the FU is worthless due to being divided

As FUE is becoming more and more popular it is important that the aspects mentioned are controlled. Donor management is vital the ensure the least amount of damaged is caused to the area

As each follicular unit is removed or attempted to be removed the density of hair is reduced, on smaller procedures the changes are less but if larger numbers are required there is a greater danger of over harvesting and leaving obvious scarring or areas of obviously reduced hair density
