What is SPL and how does it work?
SPL stands for Squared Pulsed Light. It’s not a laser; it’s a device that produces a certain kind of light that is attracted to the melanin in hair follicles. The light pulse is delivered via a hand-held wand that treats hundreds or hairs at once. At the base of each hair strand, the light is converted to heat, and the heat neutralises the hair-growing cells – causing the hairs to fall out and leading to drastically less hair regrowth.
