Wash and condition your hair using a high-quality moisturizing shampoo and conditioner. Dry hair is resistant to straightening and tends to frizz as it reaches out for moisture.
Apply a heat-activated hair product to lock in protection from the stresses of drying and straightening. Lotions and leave-in conditioners designed specifically for this purpose are available online and at drug and beauty supply stores.
Dry your hair when it is just damp, but not sopping wet. You want to retain moisture when using a flat iron, so wait as long as possible before introducing heat to your hair.
Preheat your low-heat ceramic flat iron. In the meantime, clip your hair into two-inch sections that are easy to manage.
Position the flat iron near the roots on one of the sections of hair. Pull firmly down, keeping the iron in motion at all times. Mojet warns not to apply the iron to any section of hair more than twice during a styling session. Doing so can dry your hair.
Work your way through all of the sections of your hair, from bottom to top. Allow your hair to cool completely before handling. Arrange your hair to suit your style, and then spritz lightly with hairspray to hold.
