If you're dealing with dry scalp, then make sure you're getting Omega 3's from foods like walnuts, salmon, and sardines. "Make sure it's on your plate first," Phillips explained. "Supplements are great, but its should be on your plate to start with, because that is where your best delivery is going to be."
