It involves a tiny needle, smaller than a hair, inserted into the hair follicle, which is hollow so you don’t feel discomfort.
Then a small amount of diathermy, which feels like a small burst of heat, is released into the follicle. This means the follicle will never grow again.
The heat cauterizes the tiny blood vessels supplying the hair and separates the dead hair from its base. The hair is then gently removed. Your initial appointment will include a detailed explanation of how the course of treatment will work for you.
