My scalp itches when I get hot/perspire, wear something on my head, or apply anything to hair and scalp. It's mainly the knots, biting, tangles, goo, thinning, movement, and bad hair days. Between the knots on my eyebrows, dark circles under my eyes, bad hair, and having my teeth pulled, I'm poster child for "This is what you'll look like if you don't drink your milk !! lol
