Re: Hijab, HairCutting and Dying
Muniya, although I don't have any references at hand at the moment, but there is no restriction on cutting hair, so long as I suppose you don't resemble a man or decide to go bald. From the little that I know, there shouldn't be anything wrong with dying your hair to either please yourself or your husband granted that your intention is not to mock the non-Muslims, as there is at least one ahadith that instructs us to look different from non-Muslims.
Perhaps someone else can answer your question better and correct me if I've said anything wrong.
