If you have acne or breakout-prone skin try this in the shower:
Always wash your face last.
A lot of the ingredients found in shampoos and conditioners can be fabulous for your hair, but not so great for your skin. Cleanse your skin last, and be sure to get around your ears and the back of your neck - especially if you have long hair.
This will break up any residue from your hair care products, and keep it from sitting on the skin and contributing to breakouts down the road. Happy sudsing!
