shower

ive asked my mom for shampoo and stuff like 4 times twice yesterday and twice today and she keeps saying she will in a few minuets and its been over a hour and i still haven't gotten the stuff  to shower and i have bad dandruff or sum and my head gets Relly itchy. but I've also been trying to take better care of myself and this isn't helping it at all its just making it worse... i dont know what to do at this point...
