Isabel, shaving didn't particularly help with upper lip hair but no ingrowns because this particular device didn't work for my coarse hair. I think it was using the wax strips. I tried a round of threading and it helped with pulling out some of the finer hairs by the follicle but obviously didn't do much with the ingrown hair. So now I am exfoliating with a soft cloth, applying Tendskin and wearing a wee moustache Once I get these to emerge, I plan to get them threaded.
I got my legs and underarms sugared and while it was nice, I don't think Can handle waiting for the regrowth to get to the right length in summer. I'll try it again in winter.
I am very into hair removal nowadays if you can't tell
