Nothing is more horrifying and frustrating than trying out a new body wash you were excited about only to break out in hives or pimples a couple of hours later (or even worse, immediately) after leaving the shower.

These are two fall hues that will give your dark hair lots of dimension and make for an exciting change from monochromatic brown or blonde balayage.
