(8) The leave-on time is 30 minutes at 27 C.

(9) After this time, the locks are rinsed, and then washed with shampoo and dried.

(10) The colour uptake (E.sub.ab*) was evaluated in the CIE L*a* b* system. In this L* a* b* system, L* represents the intensity of the colour, a* indicates the green/red colour axis and b* indicates the blue/yellow colour axis. The lower the value of L*, the darker or more intense the colour.

(11) The value of E* was calculated from the values of L* a* b* according to equation (i) below:
