The technique of curling with a curling iron is effective for creating curls in straight hair using heat because it provides direct and controlled application of heat to the strands. A curling iron allows for different barrel sizes, giving the stylist the ability to create various types of curls, from tight ringlets to loose waves, based on the desired look.

When the hair is wrapped around the heated barrel of the curling iron, the heat from the iron reshapes the hair's hydrogen bonds, allowing it to take on the new curl pattern as it cools. This method is popular because of its efficiency and versatility, making it easy to achieve a wide range of styling options.

Blow-drying can be used to add volume and some wave to the hair, but it is not specifically aimed at creating defined curls; hence, it doesn't fulfill the primary goal of curling straight hair. Using a flat iron can also create curls, but it's more suited for creating waves or flips rather than traditional curls. Braid setting relies on the natural wave pattern achieved through braiding damp hair, which does not involve heat and may take longer to achieve results. Therefore, curling with a curling iron is the most direct method for achieving defined curls using heat on straight hair.
