What is an important consideration when using heat tools on hair?

When using heat tools on hair, the hair's moisture content and its vulnerability to heat damage is a critical consideration. Hair that has a high moisture content can withstand heat better than dry hair. When hair is wet or damp, it contains more moisture, which can create steam when exposed to high temperatures, leading to potential damage and breakage. Conversely, dry hair lacks moisture and is more susceptible to heat damage, which can result in split ends, brittleness, and overall loss of hair integrity.

Understanding the moisture content of hair is essential for stylists, as it affects how they should approach using heat tools. For example, hair that is overly processed or colored may be more porous and less able to hold moisture, making it more fragile and vulnerable to damage when heated. Thus, taking the moisture content and overall health of the hair into account helps stylists make informed decisions about the appropriate temperature settings and duration of heat application, ultimately ensuring better hair care and styling outcomes.
