shaving doesn't make it grow back thicker, but where it cuts, it leaves a blunt, flat edge on the hair, making it coarser, so it appears to be thicker. also it's tedious and has to be done everyday, or at least every couple of days if you don't wanna be prickly!
waxing, on the other hand, can take a couple of months to grow back, and when it does, it grows back thinner than before...and actually is NOT as painful as people make out...ok, it does hurt, but no pain no gain, right? if you're gonna do that yourself, make sure you do it quickly, don't EVER wimp out halfway thru 'cos I can tell ya, THAT's when it hurts!
it's really no worse than a good hard slap is, so slap yourself hard on the butt to see if you can handle the pain first. heh. heheh.
back to the point.
those creams that supposedly disolve hair are pretty crap in general, and stink. Don't bother with them.
OR if you're really serious you could pay a sh*tload of money and have electrolosis which takes ages, is painless, and is permanent. And then you'll be bald as a baby's bottom forever!
yay!
