Coloring tip: It's a fact. The longer your hair is the older the ends are. Okay no news there. What may be news is that this makes them more porous and open to accepting hair dye. Which is why you want to get to them last if coloring at home. Otherwise they may end up darker than the rest of your strands leaving you with a final result that is well, interesting looking. Just not in a cute and sexy way.
Almost as important as the color choice is deciding how you will get there. Is this dye job a DIY project or will you put your tresses in the experienced hands of your colorist at the salon? The price tag can be considerably different depending on which direction you go.
