Beauty Mistake: Your love affair with your straightening iron has led to split ends.

Fix it: Change up your daily routine when it comes to your hair. Book a scalp massage to stimulate your hair follicles and eliminate blow-dryers and -- yes -- your beloved straightening iron, which can put stress on your tresses. If you can't live without it, at least consider not using it a couple days a week. Also look into a monthly hair mask to keep those locks hydrated.
