I put the hair colour you desire then colour the bit of hair you want.Then put your colour to black and use the roller tool and use the second thinnest line and do lines.after you do that change it to the thinnest line and do the same thing.You then need to either get white or the first two light greys and use it to make the hair shiny I suggest using the thinnest or the second thinnest to do the shine bit

I might make a animation
