Hair: If your sick there are three steps to wear your hair:
1. In a ponytail to let everyone know u feel like crud
2. Really curly or nice so that it masks ur cruddiness
3. Back to normal once you feel better!
Teeth: Once a month, use baking soda with toothpaste (only a bit) and it'll whiten your teeth.
Shaving: Make sure to use a four blade razor, it shaves closer, hair grows back later.
Skin: A mild mask (of medication for acne) once every two weeks helps. Just don't leave it on too long or it'll dry out ur skin.
Clothes: Make sure that whatever you r wearing has some color, not just one color. If it only has one color, then spice it up with shoes or accesories that r different colors (complementory) don't go monotone (one color only!)
Good luck!
