What is the effect of heat on hair during styling?

It can strengthen the hair

It can alter the hair’s shape and texture

The effect of heat on hair during styling is significant, as it can alter the hair’s shape and texture. When heat is applied through styling tools such as curling irons or flat irons, it affects the hydrogen bonds and disulfide bonds within the hair’s protein structure (keratin). This alteration allows for temporary changes, enabling hair to hold a curl, straighten out, or create various styles. The ability to mold hair into different shapes is directly related to the degree of heat applied and the technique used during styling.

Understanding this effect is crucial for hairstylists, as they can manipulate the heat setting and duration of exposure to achieve the desired results while considering the health and integrity of the hair. This knowledge underlines the importance of using heat-protectant products and employing proper techniques to prevent potential damage from excessive heat.
