What can excessive heat do to the hair?

Excessive heat can cause damage and breakage to the hair because it affects the inner structure of the hair strands. Hair is primarily made of a protein called keratin, and when subjected to high temperatures frequently, the bonds that hold this protein structure together can weaken. This can lead to several issues such as split ends, dryness, and an overall loss of vitality.

Heat styling tools, like flat irons and curling wands, can strip the hair of its natural moisture, making the hair more porous and susceptible to further damage. As moisture levels decrease, the hair becomes brittle and can break under stress. This makes it crucial to use heat protectant products and limit heat exposure to maintain healthier hair.
