What is the correct temperature for water when shampooing hair?

When shampooing hair, lukewarm water is considered the ideal temperature. This temperature helps to effectively cleanse the scalp and hair without causing any discomfort. Lukewarm water opens up the hair's cuticles, allowing for better penetration of the shampoo and treatment products, which can enhance the cleansing process and promote healthy hair.

Using hot water can strip the hair of its natural oils, leading to dryness and potential damage, while cold water may not effectively remove oil and product buildup. Room temperature water, although it may be comfortable, does not provide the same level of efficacy in terms of cleansing and preparing the hair for conditioning. Therefore, lukewarm water strikes the right balance for shampooing, ensuring both comfort and effective cleansing.
