The sun may fade your hair color and the chlorine may damage the color. In some severe cases, if you have colored your hair a very light color the chlorine may leave a green tinge to your hair. Keep your hair conditioned. Hair coloring will make your hair drier than normal. It is important to keep your hair conditioned and soft.
Conditioned hair holds color better than dry, brittle or damaged hair.
Conditioned hair also makes the colored hair shinier and brighter. Add a temporary color to give you longer wear. There are several wonderful temporary hair colors now available on the market that will give your hair a temporary color what washes out after a few shampoos. If the roots seem to be growing out a lot faster than normal, or the color looks a little faded, use a temporary color until your next permanent color application. Use layered colors to prevent an overall faded color look.
