My hair is usually pretty dry, but now I seem to have gone a bit overboard with the moisturizing treatments and my hair is all mushy/stretchy, you know the deal. Just at the ends, really. What are some good and relatively inexpensive ways to add a bit of protein quick?

My hair type is high porosity, but I think I'm somewhere between protein-sensitive and protein-craving -- the balance is hard to achieve, my hair is pretty temperamental and a tiny bit too much of either one will make my hair weak or rough. Lucky me, I know.

Oh and I live in a dorm right now, so the egg thing isn't really do-able. I would make a mess that my roommate wouldn't be too happy about x)
