Crazy Color is one of the most well-established unnatural hair dyes around so don't let the retro bottle put you off - this stuff has staying power! It also has a great range of semi-permanent colors unlike any others such as pinkissimo, peacock blue, aubgerine, violette and capri blue. This bottle contains 100ml of thick conditioning color which makes it great for using with special dyeing effects and at its reasonable price it's not expensive to try a few colors at once! The color lasts around 3-9 weeks on bleached hair, depending on the shade chosen. Not tested on animals. From our daredevils to the fainthearted, there’s a crazy Color shade to suit everyone. With 27 vibrant shades to choose from, you’ll be spoilt for choice. In order to achieve the bright, crazy Color look, it’s best to pre-lighten hair with any hair bleach for maximum vibrancy!
