are critical in hair transplantation for hairline correction(HTHC) in women. However, there are few studies on anonsurgical revisionary method for improving an unnaturalforemost hairline with thick donor hairs resulting from aprevious HTHC. Objective: To investigate the efficacy andsafety of using a hair removal laser (HRL) system to create finehairs in Asian women with thick donor hairs. Methods:Through a retrospective chart review, the HRL parameters,hair diameter (measured with a micrometer before and afterthe procedures), subjective results after the procedures,adverse effects, and the number of procedures were investigated. The reduction rate of the hair diameter was calculated. Results: Twenty-four women who received long-pulseNeodymium-Doped:Yttrium Aluminum Garnet therapy afterHTHC were included. The parameters were as follows:delivered laser energy, 35∼36 J/cm2; pulse duration, 6 ms;and spot size, 10 mm. The mean number of laser sessionswas 2.6. The mean hair diameter significantly decreasedfrom 80.0±11.5 μm to 58.4±13.2 μm (p=0.00). Themean rate of hair diameter reduction was −25.7% (range, −44.6% to 5.7%). The number of laser sessions and the hairdiameter after the procedures showed a negative correlation(r=−0.410, p=0.046). Most of the patients (87.5%)reported subjective improvement of their hairlines. Mostcomplications were transient and mild. Conclusion: HRLcan be an alternative method for creating fine hairs andrevising foremost hairline in Asian women with thick donorhairs.
