I'm going to be working salon based, usually I work mobile and really would appreciate any advice on brands and what to purchase so that I can cover my bases colour wise. Has anyone tried xp colour from salon services? If anyone happens to have a list of colours to start with so I can achieve what any potential clients want i would be greatful.... Seems like a massive headache to work out as usually buy colour as I go along depending what clients want I usually use wella
