COLORINSIDER is the newest permanent, no ammonia haircolour from MATRIX. With colour results that are true, sharp & saturated, your hairstylist will create the perfect look just for you. Unlike traditional permanent haircolours which are water-based, COLORINSIDER is Matrix's first oil-based hair colouring system. This oil-rich system optimises the efficiency of the hair colour process by facilitating the delivery of colouring agents into the hair fibre. COLORINSIDER delivers a high-definition colour result, a perfectly polished finished look with no ammonia and no odour. How it works The COLORINSIDER ODS² Oil Delivery System helps to propel colour molecules directly to the hair’s core and helps preserve the hair fibre's integrity for an even reflective looking finish* * COLORINSIDER respects the essential amino acids and lipid balance of natural hair. Other Information COLORINSIDER consists of a new range of 50 shades, allowing your professional hairstylist to give you the look you want. Imagine a warm rich brown with hints of copper and highlights of mocha. Flashes of mocha shimmer from beneath, catching the light to create movement and dimension. Or if you are looking to discover the perfect red for you - injected with depth and personality for a modern and chic look. Precision colour design accentuates the textures of your cut with graduated levels of red.
