Tracy Hayes' training head colour correction tutorial tackles a common problem - bleach growing out and a very large area of re-growth. The desired result is to have a softer blonde rather than a bleached blonde. Tracey uses a highlight blonde through the mid-lengths and roots, toning down the bleach into a softer, more natural golden blonde. This tutorial should be used in association with Parts 1, 2 and 3 which cover pre-pigmentation, grey hair with faded tints on the ends and heavily tinted black hair with a small regrowth. For these colour techniques we use a training head that many colour houses also use to teach their own students. The block has been broken up into four segments. On each segment we demonstrate a different technique for colour correction.
