Question: 1 / 400

What is the recommended water temperature for washing hair?

Cold water

Hot water

Lukewarm water

The recommended water temperature for washing hair is lukewarm water because it effectively cleanses the scalp and hair without causing damage. Lukewarm water helps to open up the hair cuticles, allowing for the removal of dirt, excess oils, and product buildup. Unlike hot water, which can strip natural oils and lead to dryness or damage, lukewarm water provides a balanced approach that maintains moisture levels. It also helps in better lathering of shampoos, ensuring a thorough cleanse without compromising hair health.

Using cold water may not be as effective at removing oils and dirt, while very hot water can lead to an unhealthy scalp and brittle hair. Therefore, lukewarm water is ideal for both cleansing and preparing the hair for conditioning treatments, making it the best choice for washing hair.
