What is a common reason for hair breakage?

Overuse of heat styling tools is a well-documented cause of hair breakage. High temperatures from styling tools like curling irons, straighteners, and blow dryers can strip hair of its natural moisture, leading to dryness and brittleness. When hair becomes overly dry, its structural integrity weakens, making it more susceptible to damage and breakage.

Proper care and protection measures, such as using heat protectants and limiting the frequency of heat styling, can help mitigate this risk. While other factors may contribute to hair health, they do not have as direct an impact on breakage as the excessive use of heat. For example, while improper cutting techniques can affect the appearance of hair and potentially contribute to split ends, it doesn't inherently cause breakage the same way high heat does.
