Punch Size refers to the diameter of the tool used in Follicular Unit Extraction (FUE) to extract individual hair follicles from the donor area. This measurement plays a critical role in determining the precision and impact of the extraction process, as well as the appearance of the donor site after the procedure.

The size of the punch typically ranges from 0.6 mm to 1.2 mm, with smaller punches preferred for minimizing scarring and preserving the aesthetic quality of the donor area. Larger punches may be used in cases where multiple follicles need to be extracted together, but they can result in more noticeable scarring if not handled properly.

The selection of punch size depends on factors such as the patient’s hair density, follicle size, and the surgeon’s technique. Smaller punches require greater precision and expertise, as they leave less margin for error during extraction.

Patients benefit from the appropriate selection of punch size, as it ensures optimal graft quality, higher survival rates, and minimal disruption to the donor area. Advances in punch technology, such as robotic systems, have further enhanced the precision and effectiveness of FUE procedures.
