Hair breakage may result from which of the following actions?

• A. Pressing hair too often
• B. Using a wide-tooth comb
• C. Applying heat protectant
• D. Washing hair daily

Answer: (A)

Hair breakage happens when the hair shaft is damaged by heat and mechanical stress. Pressing hair too often uses heat and pressure repeatedly on the strands, weakening the cuticle and cortex, and causing the hair to snap more easily. This makes it a direct cause of breakage. A wide-tooth comb detangles with less tension and actually helps prevent breakage when used properly. Using a heat protectant lowers damage from styling heat, so it protects rather than causes breakage. Washing hair daily can strip natural oils and lead to dryness or brittleness over time, but it is not the primary action that causes breakage in this list.
