Our Clareon IPL machine heats hair follicles with pulses of intense light. Some hairs are destroyed immediately, but most of them fall out over the next 5-10 days. Some follicles will survive
each treatment, so it takes several treatments to get them all.
Be aware that gray or very blonde hair is not amenable to this treatment, since the hair and follicle has to be pigmented to absorb the intense light.
