I'm with SouthernBelle on this. I occasionally use the baby powder trick. My mom told me about it a long time ago and it's always stuck with me. It does help to absorb some sweat and oil, but I think it works best when the hair has dried off a bit. A quick towel dry should do. My hair is a little shorter than shoulder length and it is on the finer side. It's not the best way to cleanliness, since it will stick to your scalp and require a wash as soon as you get home, but if you're in a situation where you can't have soiled hair (ie: work) it'll give your hair a matte appearance. You can also re-apply if you feel like you've got major sheen going on. A good tip would be to put the baby powder on your hands and then pat it onto the most oily areas. If you shake it directly onto the hair you might get a visible white patch on your hair and scalp. Not so good if you plan on leaving your hair down.
