My hair is naturally quite fine, never bothered me before but have dyed it darker and it's more obvious now. What products should I use to make it look thicker? I've never really done anything to it, just shampoo, conditioner, and occasionally a bit of argan oil on the ends when I remember. It's long so do things like mousse work or will they make it sticky vague memories of crispy moussed 80's hair and do volumising shampoos etc work or am I better off with one for coloured hair?
