Does Laser Hair Removal Work on Grey Hair?

Achieving the most effective laser treatment depends largely on a patient’s skin and hair colour. In laser hair reduction the best response is seen with dark hair and light skin. While grey, white, blonde and red hair rarely respond at all.

Laser hair removal works best on light-skinned, dark-haired individuals because the light from these lasers is absorbed by the dark pigment in the hair, also known as melanin.

A laser targets the dark pigment in the shaft and base of the hair follicles. The hair absorbs the laser energy, causing the hair to heat up and hold the heat. This heat damages the hair stunting future hair growth.

Why is grey hair not generally suitable for laser hair removal?

Grey and white hair as well as blonde and red hair both lack pigment therefore it is difficult for lasers to detect and treat. When a laser has no pigment to target it is harder to zap away the hair, thus making laser hair removal an ineffective treatment for grey hair.
