This colour service is painting colour directly onto your hair/scalp. It is a full coverage look which can be achieved with either permanent or demi colour.
A root colour is when colour is applied to your regrowth of approximately 1 inch.
A root smudge is when the colour is blended down slightly from your root.
A full head of colour is completely covering the hair root to tip.
This service can be used to give grey coverage or to smudge your root colour to create a transitional lived-in feel.
