Has anybody at the school(s) ever considered that dying ones hair can have a medical implication?
On every package of hair dye (at least in my home country, Germany) one finds a written statement: "Product may cause severe allergies. Must be discontinued immediately if rash, burns or blisters appear." The warning goes on to list many serious concerns over use of such products.
I think this is a serious argument against the school's rules.
