In one sentence, describe what the following article is about:

If you wear your hair long, it's going to turn into a bit of a sweaty mess during gym class. Try tying it up in a ponytail, and wearing accessories that match your gym outfit. You can also try tying it back in a braid or a bun for a different look. If you have shorter hair, you have a few more options available to you. You can either pin your hair to the side or wear a headband. You might even get away with just leaving it down. Avoid using gel or other product in your hair. They'll lose their effectiveness when mixed with sweat and might even run. You shouldn't wear makeup in gym class for several reasons. First, excess sweat will make it run, possibly ruining your look. Second, makeup can clog your pores. Combine clogged pores with sweat and dirt and you've got a perfect recipe for breakouts. Use a cleansing wipe to get your makeup off before gym class. If you want to wear makeup for your next class, make sure to keep your makeup in your locker. You're going to have a lot of things to carry to and from gym class: your outfit, your shoes, a towel, maybe even makeup. Not only should your bag be efficient and able to hold all these, but it should look good too. Get something that fits your style and shows off your personality.
Tie your hair up. Wipe off the makeup before class. Have an awesome gym bag.
