Hair removal using the long-pulsed ruby laser in children

Objective: The purpose of this study was to assess the efficacy of laser assisted hair removal in children aged 16 and under using the long pulsed ruby laser. Background Data: Unwanted hair in the pediatric population can be due to congenital hairy nevi and hypertrichosis. Methods of effecting hair removal include shaving, electrolysis, and laser depilation, The long-pulsed ruby laser is an established treatment modality in adults, but its use specifically in children has not been investigated. Methods: Patients aged 16 or under undergoing treatment with the ruby laser for unwanted hair were assessed. Hair counts were determined before and after treatment and an assessment of overall satisfaction was made using a parental questionnaire. Results: Treatment was regarded as successful in 25 out of 28 cases where there was a clear reduction in hair growth at the site treated with an average fall in hair count of 63% at 6 months follow up, There was no scarring or hyperpigmentation in this group and no serious complications. Total suppression of hair growth was not permanent but usually lasted between 3 and 6 months. Few problems were encountered from using the technique specifically in children, and pain was well controlled in most cases. Conclusions: We would recommend the long-pulsed ruby laser as a useful form of hair removal in children that is quick, simple and well tolerated. At present, the technique leads to hair loss that is temporary but most patients and their parents feel the treatment gives worthwhile benefits.
