Electrolysis is the only proven method of permanent hair removal. This can be performed on both pigmented hairs and blonde/grey hairs.
A fine probe (size of eyelash) is inserted into the hair follicle where a tiny burst of energy is targeted at the root of the hair. This prevents nutrients feeding the hair and hair becomes weaker and finer. After repeated treatments, hair is no longer able to grow.
Each individual hair requires repeated treatment because every individual hair has its own growing cycle and blood supply. A brand new, sterile gold probe is used for every single client to prevent cross contamination.
