When I color someone's hair, I match the color to each client's haircut, along with their everyday life. Over the years I have realized hair color and hair cuts should be done by the same person or by two people who share the exact same artistic thoughts.
 
For hair color, I am very picky about what I use. I use Joico Hair Color on all my clients. The reason I use Joico Hair Color is because when the color is processing, it is putting back the human hair protien, the only protien that really fills the gaps properly, while leaving the hair feeling and looking healthy with great shine. Plus, Joico Hair Color has a very simple color palette, leaving you, the artist, to mix your own color for each clients needs and desires.
