Shock it with electrolysis
Electrolysis works on fair hair and all skin types and it's one of the most effective ways to get rid of unwanted hair. That might just be because it uses electricity to kill off your hair matrix cells – permanently. If that conjures up memories of accidentally touching an electric fence on a country walk (hey, they're hard to see), don't worry – it's no way near as strong as that – and it's totally safe.
Your technician pops a probe straight into each of your hair follicles (they won't pierce the skin) and blast them with a small current. It'll take a few sessions to get every last bit, as your hair doesn't grow all at the same time
