(9) After this leave-on time, the tresses are washed with iNOA POST shampoo, rinsed then dried in a hood dryer at 60 C.

(10) The colour of the tresses was evaluated in the CIE L*a*b* system, using a Minolta Spectrophotometer CM2600D colorimeter, In this system L*a*b*, the three parameters designate the colour intensity (L*), a* indicates the green/red colour axis and b* the blue/yellow colour axis respectively.

(11) The variation in colour between the tresses of white hair comprising 90% natural white hairs (90 NW) untreated (control) and after treatment or dyeing are defined by (AE*) according to the following equation:
