I've had what I consider to be "frizzy" hair for years. Usually better when carefully blow-dried, but nearly always go over with GHDs. Over past year I've noticed it has got more naturally wavy/curly, which I like, except the top layer is just frizz. I would happily go over to having wavy hair if I knew what to do to make the top layer behave rather than making me look like I've just had an electric shock. Any ideas, products or (low maintenance) methods to use?
