Loréal Professionnel Dia color professional hair dressing without ammonia combines nature and Melanin Gap Filler technology with fantastic results. It offers up to 92% naturally derived ingredients, including deeply nourishing ingredients such as Shea Butter to provide maximum nourishment and promote shine during colouring. Propanediol, glycerin and hyaluronic acid provide deep hydration for the hair fibre. Over time, the melanin in the hair fibre diminishes, making the hair dull and white. Melanin Gap Filler technology perfectly mimics the natural colour and position of melanin in the hair fibre to perfectly fill in the gaps left by lost melanin. Dia color gives naturally matte hair 3x the shine that lasts up to 6 weeks. It is ideal for first dyeing natural hair, creating a tone-on-tone effect, but also for up to 70% natural coverage of first white hair. The creamy texture allows for easy mixing, application and rinsing. The fashionable shade .13 provides a cool ashy hue and a light golden sheen.Usage: 1. Wear disposable protective gloves. 2.
