The picture above is an example of a donor strip taken from the back of the head. The red section outlines a modified follicular unit, while the blue section outlines a standard single follicular unit. As shown in the picture above, you can see that hairs tend to clump in areas of 1, 2, 3, or even up to 4 hairs. These clumps of hairs are called single follicular units. For hair transplantation, follicular units of hair are separated from the donor strip and divided into units of hairs called grafts.

At NHT Medical Center, we utitlize the combination of three different sized grafts- single hair follicular unit, single follciular unit, and the modified follicular unit. Modified follicular units are grafts the size of about two single follicular units combined. However, we do not make modified follicular units bigger than 4 hairs. Using modified follicular units can yield up to two times as many hairs than using normal single follicular units.

The purpose of using single follicular units is to obtain a natural look. For the hairline, we still use single follicular units and even single hair follicular units. We agree that those are the best options for the hairline. But for density purposes, we prefer to use modified follicular units for the coverage of the rest of the area. Modified follicular units provide a thicker, fuller appearance, and are more suited to the non-hairline regions of the scalp.
