Final answer:
Permanent hair removal involves the destruction of the hair follicle, either through laser hair removal, which targets the pigment, or electrolysis, which uses an electric current.
Step-by-step explanation:
Charlotte explains to a client that with permanent hair removal, the hair follicle is destroyed, making regrowth impossible.
There are several methods of permanent hair removal, one of the most common being laser hair removal. This method uses laser light to target the pigment in the hair follicle, effectively destroying it and preventing the hair from growing back. Another method is electrolysis, which involves inserting a fine probe into the hair follicle and applying an electric current to destroy the follicle's ability to generate hair.
