Excessive heat styling and lack of moisture are primary factors that contribute to hair breakage. When hair is subjected to high temperatures from tools like flat irons, curling wands, or hair dryers, it can lose its natural moisture content. This can weaken the hair structure, making it more prone to damage and breakage. Additionally, insufficient moisture in the hair can lead to dryness and brittleness, further increasing the likelihood of breakage.

Other choices relate to less impactful factors in comparison. For instance, not using enough styling products may affect the hair's appearance or manageability, but it does not typically result in breakage. Frequent haircuts, while they might seem counterintuitive, are meant to maintain hair health by removing split ends and preventing further damage. Wearing hats frequently might affect styling or cause some friction but isn’t a direct cause of hair breakage like the combination of excessive heat and lack of moisture is.
