I'm not sure how much you can afford, but all those gimmicks are pretty expensive. Electrolysis is not that expensive for this little (relatively) hair. It's around $60 per hour and removes on average 5-6 hairs per minute.
What type of laser did you use? Is the hair coarse? If it's not, it's not surprising that it didn't work.
You also mention in your previous post about women in your family having hair issues as well. You may want to see an endocrinologist to test for hormonal conditions.
Sorry, forgot to address some of your questions. Unfortunately, right now I don't have any budget for additional services, which is why I'm bothering to do this experiment. My original thinking when purchasing the devices was that I could use them on other parts of my body that are annoying but not bothersome enought to invest in permanent removal.
The laser was several years ago, sorry I don't remember what type. It was done by a phD who was recommended by a friend. I saw a good reduction for about six months, then it either all grew back or I sprouted new hairs within a year, possibly the latter since I was in my late twenties and experiencing many other aging changes. I am an ideal candidate - pale skin, dark hair, (mostly medium-coarse) but I have read that only about 60% receive a 30-40% reduction after a year. I probably won't try laser again.
As I mentioned, I did get my hormones tested. I had a long conversation with my OB/GYN about it and she put me through an extensive battery of tests. No imbalances, so likely this is just a case of "The Curse of the Italian Grandma", much like my wide hips and frizzy hair.
