Crazy, but seemingly true. I suffer from an extremely itchy scalp. For those of you in the know about this condition, you're willing to try just about anything once to get relief. I recently read that onions, like garlic, contain large amounts of sulfur, and that some people apply onions and rub them directly onto the scalp to relieve a variety to conditions and to even grow their hair. I tried it last wash day. I can't say yet about the hair growth, but my itchies have reduced dramatically, which allows for me to go a few extra days without washing, which means less manipulation. Anyone else heard or tried this?
