Why should hair not be washed with hot water?

Washing hair with hot water primarily poses the risk of drying out both the scalp and the hair. Hot water can strip away natural oils that are essential for keeping hair moisturized and healthy. These oils serve as a protective barrier, helping to maintain the hair’s hydration and overall health. When these oils are depleted due to hot water, it can lead to dryness, brittleness, and potentially more significant issues such as breakage and split ends.

In addition to affecting the hair, hot water can also irritate the scalp, leading to conditions like flakiness or increased sensitivity. Maintaining a balance of moisture is important for the health of both hair and scalp, which is why it’s generally recommended to use lukewarm or cool water when washing hair. This helps to preserve natural oils while still effectively cleaning the hair and scalp, leading to healthier, shinier hair.
