BACKGROUND AND OBJECTIVE: Laser hair removal is
a relatively new procedure. Our purpose was to study the efficacy
and safety of a high-power, pulsed diode laser array for removing
unwanted hair.
METHODS: A total of 38 subjects were treated with
a prototype of the 800-nm diode laser system. Fluences ranging
from 10 to 40 J/cm(2) (mean, 33.4 J/cm(2)) were used and 1 to
4 treatments (mean, 2.7) were performed. Evaluation of hair loss
was performed at least 4 months after the last treatment (mean,
8.7 months) by a blinded assessment of clinical photographs.
RESULTS: A total of 59% of the subjects had only
sparse hair regrowth at the final follow-up. Higher fluences and
multiple treatments produced greater long-term efficacy. Transient
pigmentary changes occurred in 29% of the subjects and were more
common in darker skin types IV to VI (P =. 047).
CONCLUSION: The 800-nm diode laser is an efficient
and safe technique for hair reduction. Adverse pigmentary effects
occur, but are transient.
