Aww, my husband jokes about my hair all the time too...but he always says he loves the curls. When its curly he tells my son "Yay, its fun mom today!" and when I straighten it he says "uh-oh, serious mom". lol
He once took a bottle of my hair serum and put a label over it that said "Naps-be-gone serum". Gotta love the guy.
