mine blankly refuses. Ive tried and ive tried but he continues to pull it off. Hes got alot hair and is well due a haircut but as it protects his head ive left it as it is so it protects his head. It just annoyed me the other day when this women made a comment about him not wearing one. Ive make sure he drinks loads, wears sun cream and weve not even been out til late afternoon when its cooler.
