A hair straightener or curling iron uses the heat of a heating plate to curl bangs.
Date:
flat iron and curler in one A strand of hair is sandwiched between two heating plates. Heat transfer relaxes and reshapes the hair's protein structure at high temperatures. Subsequently, as the hair cools to a lower temperature, it retains its new shape—a natural curve or curl.
These heated plates are typically made of ceramic, metal, or alloy to ensure even temperature distribution. Ceramic plates are widely popular due to their stable and even heating.
As the user slowly moves curved flat iron for curling hair, rotating or twisting the hair as it passes over the plates, the hair gradually bends due to the heat and tension applied between the plates. After this step, the hair cools and sets, forming a curl or curve.
This entire process relies on precise control of temperature and contact time. As long as the heated plates reach the critical point for "restructuring" the hair, and the hair is moved between hot and cool zones using specific techniques, a natural curl effect can be achieved for bangs or the ends of the hair.
