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.
Hair color product web sites offer the entire range of hair color available with them and what can be done with it. However, do remember that they are using professional models (with amazing skin) and you would need to discount some of the ideas that they demonstrate. The official web site however, does help you get the right shade and that is very important before you decide your hair color.
