In contrast, titanium plates heat up quickly and provide high temperatures but can lead to potential heat damage if not used carefully.

The underlying mechanism involves the interaction between hair structure and heat. Coarse curly hair has a thicker diameter and a more complex structure compared to straight hair, making it more resistant to change. When using a flat iron, the right plate material can ensure that sufficient heat is applied uniformly, allowing the bonds within the hair to be altered effectively. Additionally, tourmaline-infused plates release negative ions that help reduce frizz and static, further enhancing the straightening process for coarse textures. Thus, the choice of plate material not only impacts the immediate styling results but also the long-term health of coarse curly hair.
