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

Using high heat tools on hair often leads to damage and dehydration because excessive heat can strip the hair of its natural moisture and oils. When hair is exposed to high temperatures, the heat can weaken the hydrogen and disulfide bonds within the hair structure, resulting in brittleness, increased breakage, and frizz. Over time, this can manifest as split ends, dryness, and a lack of elasticity, making it crucial for individuals who frequently use heat styling tools to implement protective measures, such as using heat protectant sprays and limiting the use of high temperatures.

While high heat can sometimes contribute to shine or temporarily enhance volume by styling, these effects are often short-lived and do not mitigate the underlying damage caused by the heat. Increased shine and improved color retention do not typically result from the high heat; in fact, they can often be compromised due to the harm inflicted on the hair's cuticle layer.
