How can environmental factors affect a client's hair?

Environmental factors play a significant role in the health and appearance of a client's hair, and the correct answer highlights two important aspects: humidity and pollution.

Humidity is a common environmental factor that can lead to frizzy hair. When the air is humid, water vapor is present, which can cause the hair cuticle to lift, resulting in a frizzy or unmanageable texture. This effect is particularly noticeable in individuals with naturally curly or wavy hair, where the increased moisture in the air can exacerbate frizz and reduce the smoothness of the hair.

Pollution is another environmental element that can impact hair health. Pollutants from the air—such as dust, smoke, and other chemicals—can accumulate on the hair and scalp, leading to build-up. This build-up can weigh down the hair, make it appear dull, and potentially irritate the scalp, which might contribute to other issues such as dandruff or hair loss if not properly addressed through cleansing.

By understanding how these environmental factors affect hair, cosmetologists can better advise their clients on appropriate hair care routines, product choices, and styling techniques to mitigate these effects and maintain healthy hair.
