SensiDO Trillion Tones by Rebecca Taylor is a hybrid colour, not just a direct dye, demi or permanent, but all. It's the stylist's choice to create their own color unique shades.
The SensiDO Trillion Tones concept is a compact colour line that gives every hairdresser the ability to break traditional boundary fences. The colour line includes five intense colours, five pastel colours, and white, which when combined you can create trillions of colours and shades for treated, untreated, or grey hair.
How does this product work? The 3 major components are direct pigments, alkaline and developers.
Direct Dyes - You can easily and quickly create trillions of different shades of colour, with only imagination as a limit.
Alkaline - helps pigments penetrate deeper into the hair shaft, ammonia boosts the lightening process by acting as a catalyst when mixed with hydrogen peroxide (developer).
Developer - causes oxidation; the released oxygen lightens the natural melanin pigment and also creates longer lasting colour.
