Tracy Hayes’ head block colouring tutorial teaches the colour correction of grey hair with faded tints on the end, by bleaching and adding highlights and tints. This tutorial should be used in association with Parts 1, 3 and 4 which cover pre-pigmentation, heavily tinted black hair with a small regrowth and grown out bleach with a large area of re-growth. For these colour techniques we will be using a block that many colour houses also use to teach their own students. The block has been broken up into four segments. On each segment we will be showing you a different technique for colour correction.
