What effect can heat styling have on hair if used improperly?

Heat styling, when used improperly, can lead to dryness and damage in hair. The process of applying heat can strip moisture from the hair shaft, causing it to become brittle and leading to split ends and breakage. This is particularly true for excessive or direct heat application, which can compromise the hair's structural integrity over time.

Additionally, repeated heat exposure can weaken the hair's protein structure, resulting in a lack of elasticity and an overall unhealthy appearance. Using tools like flat irons, curling wands, or blow dryers without proper heat protectants or adequate temperature control increases the risk of such damage. Educating clients on appropriate heat styling techniques and the importance of moisture will help maintain hair health and reduce damage.
