When you pluck, wax or thread, you are removing the hair by the root and the actual follicle is being yanked below the skin. Shaving is actually much safer and less likely to cause problems but it can cause stubble since the hair is blunted, razor burn and ingrown hairs (avoided by using an electric razor and aftercare). I still just pluck because it's only a few hairs but I've researched this topic very thoroughly because they really do bother me. I even made my husband promise to pluck them if I'm ever in a coma or incapacitated for any reason. The only way to get rid of them permanently would be electrolysis but that can sometimes cause mild scarring and i would seriously prefer a few hairs to some scars ya know? But if it gets bad enough I would reconsider because it really does bother me deeply. It can really bring me down sometimes and I get angry at myself for caring so much.
