Question: 1 / 400

What should be the temperature of water when washing a client's hair?

Hot

Cold

Lukewarm

Lukewarm water is the ideal temperature for washing a client's hair as it provides a comfortable and soothing experience. It is warm enough to effectively cleanse the scalp and hair without causing discomfort or irritation. Using lukewarm water helps to open up the hair cuticles, allowing for better penetration of shampoos and conditioners. This balance also minimizes the risk of stripping the hair of its natural oils, which can happen with water that is too hot.

While warm water can be a comfortable alternative and promotes effective cleansing, it's important to ensure that it is not too hot, as this could lead to scalp irritation or discomfort for the client. Cold water, on the other hand, is less effective for cleansing, as it does not adequately remove product build-up or oils, and hot water risks damaging the hair and scalp. Therefore, lukewarm water strikes the best compromise for comfort and efficacy during hair washing.
