Wash off, and then mix 8.3 with 75ml warm water, sponge into the pre-
bleached hair, after 20 minutes mix fresh colour this time with 75 ml 6%
peroxide, and apply from root to ends in one application and activate for
40 minutes.

The following tables show exactly the formulations needed to achieve all
target colours. The large solid basic shade on the left is the client’s
natural colour, and all the numbers on the right are potential target
shades. Beneath the target numbers are the peroxide strengths needed to
achieve that particular target shade, on the particular natural base shade
on the left.

The letters PB mean pre-bleach with the peroxide strength next to them,
and the colour fill behind the information is the level of pre-bleaching
needed for a perfect base shade to apply the target colour on top.
