Tonology creates a new precedent in colouring. After long researches Tonology changes the views: The Ins-Pyrence Complex. Ins-Pyrence Technology combines different techniques to create a unique colouring. This emerging technology is divided in three different types:

The Colouring Cream: The colouring cream respects the hair fibre due to the reduction of ammonia applied in colouring. The cosmetic cream has an easy dilution technique with the same density as our innovation, thus the hairs mixing and dyeing processes are easier. The reduction of the amount of ammonia and the other transmitting actives applied, make our colouring stand out by its anti-irritate quality.

The Colour: the intelligent colourings, which are electrically charged (+), have a very low molecular weight and facilitate the colour penetration in the hairs cuticle and cortex, as well as facilitating the colouring process in dark and damaged hair.
This new generation of hair dyes allow the colour to last two times longer providing an outstanding intensity even in brown, ginger, blond or violet shades.

Hair sheen and moisturising: we apply several complexes to our colouring cream in order to recover hairs sheen, moisturising and intensity:
- Hydrolyzed wheat protein provides an optimum conditioning effect.
- A coconut amine derivative is exclusively used to provide softness to hair
- A soya derivative provides the dyeing with a perfect amount of colour.

All the effects supplied by these components make the hair cuticle be perfectly sealed, increasing its shine and reducing hair breakage in a 10%.
