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

Using high heat during styling can significantly impact the hair's integrity, leading to potential damage and breakage. Hair is composed of proteins and moisture, and when exposed to excessive heat, these components can be compromised. The high temperatures can cause the protective outer layer of the hair shaft, known as the cuticle, to become damaged or lifted. This results in moisture loss, increased porosity, and ultimately, weakened strands that may break or become frizzy.

It's crucial to recognize that while there are styling techniques that can enhance softness and shine, these effects are typically achieved through the right products, techniques, and moderate heat usage, rather than from excessive heat. Similarly, high temperatures do not contribute to moisture retention or improve color longevity; rather, they can adversely affect the hair's condition and color vibrancy. Understanding a balance in styling practices, including appropriate heat application, is essential for maintaining healthy hair.
