Condition your hair right. To get curly, frizz-free hair, keep your locks moisturized and healthy. Condition after each shampoo with a moisturizing conditioner, and also use a deep conditioner once every two weeks before combing out your wet hair. This lubricates your hair and helps your brush or comb go through your hair more easily.
Apply a small amount of an anti-frizz serum through your hair, starting at the ends and working up to the roots. Scrunch your hair gently as you apply the product, and try to get it as evenly distributed through your hair as possible.
Stop using relaxers and other smoothing, straightening treatments and products on your hair. Even though you may want your hair to be straight some of the time, the more often you do it, the harder it is to get your hair to go curly again.
Use the right products for styling, like a bit of mousse or gel. Twist sections of your hair around your finger and then blow-dry with a diffuser to get the most volumized, spiral, frizz-free curls.
Heat a curling iron and use it to touch up around your hair for a perfect head full of curls. Use a curling iron with a smaller barrel for tight spiral curls, and one with a larger barrel for big, loose curls.
