I as well have never seen a client need treatment longer than two years on the one area.
Does your practitioner know that you are tweezing?Has she questioned why your treatment is taking this long? Eletrolysis is permanent hair removal and when i work on a client this is what i work so hard to achieve PERMANENT HAIR REMOVAL!!I want to see the results of my hard work.If I had a client that was tweezing/waxing while i was treating her I would refuse to continue to treat. I would tell the client that they are wasting their money.
You have to be strong and make a decision, do you go ahead with electrolysis and do it properly or do you want to tweeze and continue to have this problem forever.
Maybe set a plan have a back up electrologist so if your electtrologist goes on holidays you can make an appointment with the back up.
When you travel three times are year, do some research before you travel to find an electrologist that may be able to work on you in the country you are going, book an appointment ahead. I had a client who was getting electrolysis treatment in the states and she would continue her treatment with me when she came to Australia two to three times a year to visit her family. She kept her treatment up so she would not get tempted to go back to her previous method of temporary hair removal.
