What impact can excessive heat exposure have on hair?

Excessive heat exposure can have several negative effects on hair, and one of the most significant impacts is that it can lead to dryness and split ends. When hair is subjected to high temperatures from styling tools like flat irons, curling wands, or excessive blow-drying, the moisture content of the hair strands can be depleted. This results in a loss of elasticity and creates a brittle texture, making the hair more susceptible to damage. Split ends occur when the protective cuticle of the hair is damaged, causing the hair to fray and break. Therefore, managing heat exposure is crucial for maintaining healthy hair and preventing these common issues. Understanding the effects of heat on hair allows barbers to better care for clients and offer informed advice on hair care practices.
