1. Allow strands to air-dry, then rub nourishing oil like Shu Uemura Essence Absolue Nourishing Protective Oil ($65; shuuemura-usa.com) into the ends, not the roots. "It keeps hair manageable and protects against heat," Muradian says.
2. Wrap 2-inch sections on a curling iron; twist down from top and hold ends in one hand. Go around the entire head, keeping curls unfussy by not clasping the iron shut. Muradian uses the powerful Chi Turbo Digital 1 Inch Curling Iron ($105; target.com).
3. If your hair looks frizzy, spray on holding mist and follow with a blast of strong-hold hairspray.
