The follicular units, also known as the hair follicles intended for transplantation, vary in number from person to person in a single session. On average, around 2000 follicles are transplanted in one session, depending on the individual’s specific hair follicles. However, some experts suggest that this number may be higher. Although experts do not recommend it, in very rare cases, individuals with severe hair loss in the seventh stage and a defect-free donor area may receive up to 6000 follicles in a single session. This scenario is extremely rare.
