Which type of hair requires more pressure during pressing for effective straightening?

Coarse hair requires more pressure during pressing for effective straightening because of its thicker and stronger structure. This type of hair often has a tighter cuticle layer, which can resist changes in texture and shape more than finer hair types. To achieve desired smoothness and straightness, additional pressure is necessary to break down the bonds effectively and allow the heat from the pressing tool to penetrate the hair more thoroughly.

Coarse hair usually has more volume and body, making it less responsive to gentle pressure when being pressed. Ensuring that sufficient pressure is applied will help in achieving a straighter look that lasts longer. In contrast, fine hair may require less pressure, as it is more susceptible to damage and heat can more easily alter its shape. Medium hair falls in between, often needing a balanced approach, while curly hair, though it can also be coarse, may have specific styling considerations that don't always relate directly to the pressure applied during straightening.
