Classification of the female hairline and refined hairline correction techniques for Asian women

Abstract

BACKGROUND: Hair transplantation has been a highly effective technique in reducing wide foreheads and recontouring the hairline.

OBJECTIVE: To classify hairline contour in Asian women and to find a way to make an ideal and refined female hairline.

MATERIALS & METHODS: The hairline contours of 234 female volunteers were classified into five groups. We measured the height and width of foreheads and maximal depth of the infratemporal portion. We also performed hairline correction on 350 female patients with a wide forehead with an M-shaped hairline.

RESULTS: Hairlines of the volunteers were grouped as round (27.35%), M-shaped (28.20%), rectangular (27.35%), bell-shaped (10.25%), or triangular (2.99%). The average height of the forehead was 6.38±0.89 cm, average width of the forehead 14.30±1.75 cm, and maximal depth of the infratemporal portion 4.29±0.77 cm. In 350 patients operated on, the average area of the frontotemporal recess was 30.1 cm(2), and approximately 1,054 follicular units (FU) were needed.

CONCLUSION: The classification of Asian female hairlines and our refined techniques will be beneficial for correcting wide foreheads with M-shaped or rectangular hairline contours.
