No time to dye but in need of a quick fix?
Blonde: Dark roots and platinum tips usually aren't flattering on most women. A few Chammomile tea bags brewed in two cups of water for about twenty minutes can work wonders. Just brew the tea and then wait for it to cool to luke warm. Next, add the tea to a spray bottle and spray your whole head of dry hair. Wait 30-40 minutes before shampooing out. This will help lighten one to two shades for blonde or light brown hair.
Brunette: A strong cup of brewed coffee should be sprayed or combed through your hair, after it's cooled to room temp. of course. Shampoo out after approx. half an hour. Adds subtle highlights to black hair, and makes brunette hues more shiny.
