Hi xcvq

yep 1 min 30 sec after i have applied. what i do is i have a plastic bowl i pour half of the wella meduim ash brown colour into the bowl followed by half the bottle of the colour drabber then add wella 20 volume developer 1oz exactely. mix all 3 together making sure your wearing gloves. Then add approx 6oz of warm water and mix.

Now i just lay the the piece into the bowl working the colour through to the ends for about 30 sec then remove and lay the piece on the bowl's plastic lid wait for 1 min 30 sec then rinse the colour out and shampoo using loreal pure colour protect. then i add the remaining colour to my own hair which takes a minute or so to work in then leave for 25min rinse and shampoo using the same product.
