The practice of cleansing and conditioning predominantly refers to which service?

The practice of cleansing and conditioning predominantly relates to skin care services. This is because cleansing is a fundamental aspect of skin care, aimed at removing dirt, oil, and impurities from the skin's surface to maintain its health and appearance. Conditioning often involves the application of moisturizers or treatments that enhance the skin's hydration and texture, which is also a key component of skin care routines.

Hairstyling services, while they may include some cleansing and conditioning through shampoos and conditioners, primarily focus on the styling of hair rather than the cleansing and conditioning itself. This makes skin care services the most accurate answer in the context of the question, as they are explicitly dedicated to the care and treatment of the skin, emphasizing the importance of cleansing and conditioning in maintaining healthy skin.
