Paul Mitchell® The Demi is a vegan, demi-permanent, no-ammonia liquid colour that conditions the hair while colouring to deliver incredibly rich results with exceptional shine. The MEA free, no-lift formula won't lighten the hair's natural pigment. Its mix of direct and oxidative dyes create longer-lasting results that deliver up to 4-6 weeks of colour. The versitile formula is ideal for a wide range of professional colour services, including toning and refining, grey blending, colour refreshing, and colour correction services. The fast 5-20 minute processing time allows creative control over minimal to maximum colour deposit, for easy tonal adjustments and colour correction services. It mixes to a perfect gel consistency allowing for quick no-drip application with a bottle or brush. Plant-based lipids and oleic acid conditions and nourishes the hair for a silky feel and styling control, while soy protein smoothes the cuticle to soften and hydrate.
