Evaluation of a long-pulse Q-switched Nd:YAG laser for hair removal.
BACKGROUND
Hirsutism and hypertrichosis are common problems for which a permanent solution has been elusive. Laser-assisted hair removal is a promising technique. However, the optimal wavelength, pulse duration, and fluence continue to require further investigation.


OBJECTIVE
To determine if the long-pulse Q-switched Nd:YAG laser is safe and effective in reducing facial and non-facial trunk hair.


METHODS
Fifteen patients were treated with a 30 msec pulsed Q-switched Nd:YAG laser at fluences between 125 and 150 J/cm2. The reduction of hair density was assessed at baseline and at 7, 30, and 90 days after treatment. Potential complications were also evaluated.


RESULTS
The average hair reduction was 36% at 7 days, 52% at 30 days, and 59% at 90 days. No significant complications or adverse events were reported.


CONCLUSIONS
The long-pulse Q-switched Nd:YAG laser provides a safe and effective means of hair removal.
