Ruby Laser-Assisted Hair Removal: Long-Term Results After Repeated Treatments

The study evaluated the efficacy of ruby laser-assisted hair removal in 88 patients treated monthly for 4 months, with hair density measured at 7 and 12 months post-treatment. Results showed an average hair density reduction of 13.7% at 1 year, which was statistically significant. Although only 44.3% of patients experienced reduced hair count at 1 year, 79.5% were satisfied with the treatment. The long-pulsed ruby laser was found to be effective in permanently removing a small proportion of unwanted dark-colored body hair, and patients preferred it over conventional methods due to its ability to slow hair growth, thin hair, and provide good temporary control. No adverse long-term side effects were observed.
