Bold, Bright Crazy Color is exactly what it sounds like. Bold, bright, crazy colours in a semi permanent hair colouring range. Featuring the brightest intermixable greens, yellow, pinks and reds in semi-permanent form, Renbow Crazy Color creates vivid results that last 10-12 washes. Ammonia Free Renbow Crazy Color is an ammonia free hair colouring range. Ammonia strips the natural moisture out of hair, as well as being painful, irritating or damaging to your clients skin. Using ammonia free dye means you can spend less time worrying about minimizing contact of dye and skin and more time perfecting your client's look! Vegan Renbow's messaging around animals on their Crazy Color range has been clear and their passion for protecting animals matches their passion for colouring hair. Renbow Crazy Color is 100% vegan hair friendly and 100% cruelty free in testing procedures.
