Question: 1 / 400

What is the effect of excessive heat on hair?

Strength loss, dryness, and split ends

Excessive heat can have detrimental effects on hair, leading to strength loss, dryness, and the formation of split ends. When hair is subjected to high temperatures from styling tools such as flat irons, curling irons, or blow dryers, the moisture within the hair can evaporate. This loss of moisture can cause the hair cuticle to become damaged and weakened, making it more prone to breakage.

Additionally, as the hair becomes drier, it may lose its natural shine and appear dull. The repeated application of heat can cause the protective layer of the hair shaft to peel away, which can further exacerbate issues like split ends. This understanding is crucial for hair care professionals, as it highlights the importance of using heat protectants and moderating heat exposure during styling to maintain hair health.
