BACKGROUND: Different types of lasers are used in the removal of undesirable hair by targeting the hair follicles, with the melanin pigment acting as the chromophore, and through the mechanism of selective photothermolysis. OBJECTIVES: This report documents an unusual increase in terminal hair growth after alexandrite laser hair removal in three female patients. CONCLUSION: Excessive hair growth after alexandrite laser hair removal must be listed as one of the complications resulting from the use of a laser with a fluence that is too low and can possibly be prevented if we use higher energy to fully destroy the hair follicles, with consideration given to the skin type and an effective cooling system.
