Follicular Units
A follicular unit is a natural group of hair follicles in the scalp, typically containing 1 to 4 hairs. These units are the basic building blocks of hair growth, aligning in specific patterns across the scalp. In hair transplantation, surgeons harvest and transplant these intact units to maintain a natural look, as they retain the original hair arrangement and density. Understanding follicular units helps ensure a realistic, natural appearance after transplantation by mimicking the scalp’s natural hair pattern.
