Have you wondered why there are so few doctors worldwide doing FUE in African Americans. Infact it takes a lot of experience and expertise to do FUE hair transplant in African American type of hair. The African hairs have a curl as a result of which the chances of cutting the hair follicles are more during extraction and graft preparation. So we generally do a FOX Test to determine the possibility of FUE & transection rate.

Skin tightness with which follicular units are held in dermis varies and hence FUE may not be suitable in all patients. Therefore, before undertaking any patient for FUE hair transplant, the surgeon should ascertain whether the patient is a suitable candidate for FUE or not. In FOX test, the surgeon takes out a few (about 100) grafts from the donor area and then evaluates how many complete/incomplete follicular units are extracted.
According to the ease and completeness of extracted grafts, Bernstein and Rassman classified FOX test into five grades.
- Grade 1 is when intact follicular units literally pop out of the scalp or when there is only occasional transection of individual hairs in the unit.
- In Fox grade 2 patients, extraction may be relatively easy in the first session, but in subsequent procedures (when the donor area is slightly scarred) it becomes more problematic and the yield starts to decline. In these patients, the longterm yield can be compromised and planning extremely difficult.
- In FOX grade 3, the emergent angle is difficult.
- In Fox grade 4-5 (when it is almost impossible to predict the emergent angle), the yield is too low for the FUE procedure to be successful. Here, the decision not to use FUE should be straightforward as the transection rate would be too high.
If the patient is FOX-positive (grade 1–3), the surgeon can go ahead with FUE.
