I kinda get the impression that Raph has a thing about control - Obviously Andrew was in charge of dyeing his hair and asking Hannah to leave and then when she didn't want to, asking Andrew to dye his hair in the toilet as a way of controlling the situation. I don't think he's a controlling person, but I don't think he was very comfortable getting his hair dyed by Andrew and possibly saw it as a weakness, which is why he didn't want her around.
