Thou Shalt Use Heat With Care
Using flatirons and blow dryers directly on twists can cause them to go limp — permanently. The best way to avoid heat damage is to use indirect methods of drying. A hood dryer or diffuser will help dry your curls without singeing them. If you do plan to blow out your hair, use a heat protectant to protect your strands like SheaMoisture Zanzibar Marine Complex Heat Shield Cream ($11).
