Red Seal Hairstylist Practice Exam

Humidity typically affects styled hair by introducing excess moisture into the hair cuticle. When the levels of humidity in the air rise, the hair absorbs this moisture. This process can lead to frizz, as the hair strands may swell and lift away from each other instead of lying smoothly. The moisture disrupts the alignment of the cuticle layer, causing strands to become more porous. Consequently, instead of retaining the intended style, hair often looks unruly and less polished.

While options that suggest enhancing shine, easing styling, or encouraging curl definition might seem plausible, they do not accurately reflect the common experiences associated with high humidity. Enhanced shine often occurs when hair is well-moisturized and in good condition, but excess humidity specifically leads to frizz rather than shine. Additionally, styling can become more challenging in humid conditions because the moisture interferes with the products used to achieve and maintain styles. Lastly, while some individuals may find that their natural curls are accentuated in humid weather, it is generally the case that humidity is more closely associated with frizz and less with defined curls for many hair types.
