What can excessive heat styling do to hair?

Excessive heat styling can cause damage and breakage to hair due to the high temperatures involved in processes such as curling, straightening, or blow-drying. When hair is exposed to heat above a certain threshold, the keratin protein that makes up the hair shaft can denature, leading to weakened strands. This can result in various forms of damage, including dryness, brittleness, and split ends. Over time, the cumulative effects of repeated heat exposure can lead to significant structural damage, making hair more prone to breakage.

Heat styling may produce temporary enhancements like shine, improved texture, or increased volume, but these effects are not sustainable and come at the cost of the hair's overall health. It is crucial to use heat protectants and limit the frequency of heat styling to maintain the integrity of the hair.
