Also, if this really bugs you, try permanently removing the hair by lazer hair removal. I did 1 session once and all the hair grew right out with absolutely no bumps at all. It grew back though because it takes about 6 sessions to kill the hair in every growth cycle...I haven't had the money yet, but when I do, it's a definite for me.
You're supposed to scrub the area in the shower first before shaving to prep the area...don't overdo it, but it gets rid of the dry skin, bacteria, and ingrowing hairs. After that, shave only in the direction the hair is going. Ideally you will use a shaving cream with vitamin E. Vitamin E is really supposed to help, if it doesn't put some neosporin in that area, because it's just ingrowing hair issue (which are small cause pus).
I know of a product called Afterburn too that is supposed to help
What helps sometimes is to apply some cream to moist and lubricate the skin. Just after shaving and after every shower.
hey this happens to me too. its just an irritaion from shaving. if the hair is too short the bumps will be worse. if you leave the hair a little bit longer it may not happen as much or be as bad.
always make sure you have a sharp blade cos blunt ones will make it worse. :)
