Which method is commonly used to straighten curly hair temporarily?

Heat styling is a widely accepted method for temporarily straightening curly hair. This technique utilizes tools such as flat irons, curling irons, or blow dryers with a brush to apply heat directly to the hair cuticle. The heat causes the hydrogen bonds in the hair to break temporarily, allowing the hair to be molded into a straighter shape. Once the hair cools, it retains the new straightened form until it's exposed to moisture or washed, at which point the natural curl returns.

This method is effective for achieving smooth and straight hair relatively quickly while allowing for styling versatility. In contrast, other options like hair rolling and blow drying can enhance curls or volume but do not necessarily straighten hair in the same effective manner as heat styling. Chemical relaxing offers a more permanent solution, fundamentally changing the hair structure, but it does not apply to the temporary nature of the question. Heat styling remains the go-to approach for those seeking to switch up their hairstyles for short periods.
