How heat can damage the hair and scalp?

Heat can damage hair and scalp by stripping moisture, leading to dryness, brittleness, and increased breakage. Excessive heat from styling tools can alter the hair's protein structure, making it weaker and more prone to split ends. On the scalp, high temperatures can disrupt the natural oil balance, potentially causing irritation or inflammation. Prolonged exposure can also weaken hair follicles, possibly affecting hair growth.
