What is the Difference Between DHI and FUE

Hair transplant is becoming common for both male and female pattern hair loss currently. DHI and FUE are both equally effective hair transplant methods for treating female and male hair loss. In fact, DHI is a modification of the FUE. Both techniques are safe procedures and are very popular among females and males.

The key difference between DHI and FUE is their procedure. In FUE, each hair follicle is extracted manually from the donor area and surgically implanted by hand into the area of treatment on the scalp, while in DHI, a pen-like medical device is used to harvest hair follicles from the donor area on the scalp and then implant the hair follicles one by one into the treatment area on the scalp.

What is DHI?

DHI stands for direct hair implantation. It uses a pen-like medical device to harvest hair grafts or hair follicles from the donor area on the scalp and implant the grafts one by one into the treatment area on the scalp. This procedure uses a specialized tool known as the DHI implanter or Choi pen. Choi pen allows greater control over the depth, direction, as well as the angle of each implanted hair follicle.

DHI technique reduces scalp trauma. It also results in a denser and more natural hair growth pattern. However, DHI procedures can be more time-consuming than FUE due to the meticulous nature of the method.

What is FUE?

FUE stands for follicular unit extraction. During this procedure, each hair follicle is carefully extracted from the donor area and individually transplanted by hand to the treatment area, where it is precisely implanted into the scalp.

The FUE method of hair restoration was introduced before the DHI method. Though it causes minor scalp irritations, this procedure can be completed within a comparatively shorter period of time. Furthermore, in this procedure, hair typically begins growing back in about 3 to 4 months.
