What is a common effect of using heat tools on hair?

Using heat tools on hair can lead to damage or dryness if they are not used properly. When hair is exposed to high temperatures—such as from blow dryers, curling irons, or flat irons—without adequate temperature control or protection, the hair's cuticle (the outer layer) can become compromised. This can lead to moisture loss, resulting in dry and brittle hair that is more prone to breakage.

Heat tools can also cause the protein structures in the hair to break down if the temperature is too high or if the tools are used too frequently. This can lead to irreversible damage, making it essential for stylists and individuals to use heat protectants and adhere to proper heat settings to minimize negative effects. Therefore, understanding the potential consequences of heat styling is crucial for maintaining healthy hair.
