Disconnected layers can leave you with a mullet that was popular in 1985, but not fashionable in 2013.
Slice cutting and blending will help even out a disconnected layering job. A fair skinned person should use cooler hair colors, such as soft browns and reds. Choosing highlights that are too light can wash out your face and make you look too pale or older.
Keep your color looking nicer longer by using color safe shampoos and conditioners. Make sure these are sulfate free products.
