there seems to be a new hair fashion. grey hair. saw two young women with what looked like badly done grey hair. blue in places. i guess all the other colors got old.
Yup, it comes with a blueish or violet haze. First there is massive bleaching, but because there most of the times is a bit of yellow remaining, they ad some blue or violet to neutralise the yellow.
In my village there are only three now and then going for "weird" colours in their hair.
But since the grey is an option, there are quite a few "grey" people walking around.
So, in stead of other colours going old, this could be for people who don't have the guts to go for green or purple, yet they want to stand out, in a mild and "sophisticated" way.
