I used Loreal Preference Dark Brown and it turned out beautifully. It is actually softer and shinier after dyeing. It had nice, subtle, natural looking high and low lights too. Very nice. I think you can get a coupon at Loreal.com.Whats the best box hair color product i can get a store?
you will need to see a proffessional. depending on the depth of hair, it will throw red orange or gold. you need to counteract this with different colours that you buy. it needs to be a cool colour such as ash. it depends whether your desired colour is lighter than your natural colour, or your natural colour is in fact natural or you have previously coloured it. if so it is way safer to use a proffessional. you may end up ginger!
