What technique is used for temporarily straightening curly hair using heat?

Hair pressing is the correct technique for temporarily straightening curly hair using heat. This method typically involves using a heated iron, which is pressed against sections of hair to smooth and straighten it. The process allows for a sleek finish while maintaining the hair's natural movement, making it an effective choice for achieving temporary straightness.

Though other techniques like blow drying and flat ironing can also straighten hair, they function in different ways. Blow drying involves using airflow and heat to dry and style hair, which may not always result in a straightening effect unless paired with a specific technique, such as using a round brush. Flat ironing, while effective for straightening, usually requires a more intensive approach and may lead to more permanent results, depending on the hair type and the heat settings used. Smoothing is a more general term that can refer to various methods aimed at reducing frizz and enhancing shine but does not specifically denote the technique associated with heat and temporary straightening like hair pressing does.
