Using hot water followed by a cold water rinse is not recommended for hair washing in a barbershop due to the potential for hair damage and client discomfort. Hot water can strip natural oils from the hair, leading to dryness and making the hair more brittle. Additionally, a sudden transition from hot to cold water can be shocking to the scalp, which may not be a pleasant experience for clients.

In contrast, using lukewarm water is beneficial as it helps to cleanse the hair without causing irritation or stripping away moisture. Washing hair before a haircut is also advantageous as it removes product buildup and allows for a more precise cut. Applying conditioner after cutting is a beneficial practice as well, as it helps to hydrate the hair, making it easier to manage and style post-cut.
