I have serious hair-envy of Carrie Underwood. Sometimes you know when your hair needs some help (split ends, dry or breaking...) but it can be hard to tell exactly whats going on and what your hair needs to be healthy. Fortunately, I just learned this hair test!
Its called "Sink or Swim": just drop one strand of hair into a glass of water. If it floats, you're healthy and good to go. If it sinks, that can mean your hair needs more protein. Make sure you do the test with 3 or 4 different strands, from different parts of your scalp.
