Hi was wanting some advise on pre softening! I have a client who has very resistant white hair I use matrix 508N on her which has worked great but the last few times hasn't covered 100% like usual! I've tried a few different things n I'm doin her hair tomorrow so was goin to see if pre softening would work!!! I usually do bleach highlights with the colour inbetween on the regrowth! Can I just do the highlights then go straight in with a 6% then go straight over the top with 508N or do I need to pre soften before the whole process rinse then do colour application as normal??? Thanks in advance x
