Don't Brush Your Hair When It's Wet
You should detangle hair right after you wash it, but use a wide-toothed comb. The thin, narrowly spaced bristles in a brush can snag and break wet hair, says Philip Pelusi, owner of Tela Design Studio in New York City. The teeth on a wide-toothed comb, however, are large, set far apart, and usually plastic and slip through hair easily.
