I suppose it’s what “4-years” means? And, what “a significant amount of time” means? See, what’s “significant” to you, might not be to the experts here on Hairtell. Maybe it’s appropriate?
It would be better for you to disclose the actual “treatment hours” you have spent on your face, and the extent of the hair problem.
For example, I just saw one of my clients who mentioned that she’s “been coming to me for ‘over’ 30-years!” And, actually that’s true.
However, in that entire period, she has not completed even 2-hours of treatment time. Her last 15-minute treatment with me was more than 15-years ago. She has never done consecutive treatments. I mean she will have a treatment and then I won’t see her for several years. (And, of course, she had been tweezing right up until the time of her appointment.)
So, there you have it. As far as getting her to commit to really getting this job done? I just gave up.
Frankly, I commonly finish off beards in less overall time than the “pesky” cases of “not so much” facial hair on women.
So, take the time and add up the actual hours you have spent on this project. This will give us a better chance to speak to your case.
