This tool serves as a pre-operative assessment method utilized in hair restoration planning. It provides an estimate of the number of follicular units, each containing one to four hairs, that may be required to achieve a patient’s desired hair density and coverage across the balding or thinning areas. For example, if an individual presents with a Norwood scale level 3 pattern of hair loss and wishes to restore density to the frontal hairline and mid-scalp, the tool assists in approximating the follicular unit grafts necessary to address these specific zones.
The value of this estimation lies in its contribution to setting realistic expectations for both the patient and the surgeon. It informs the feasibility of achieving the desired outcome based on the patient’s donor hair availability. Historically, surgeons relied on visual estimations and experience. The introduction of this quantifiable assessment offers a more objective and data-driven approach, potentially leading to improved surgical planning and patient satisfaction.
