Using expired hair products can lead to potential hair damage or irritation due to the degradation of their active ingredients and preservatives over time. As products expire, the chemical stability may diminish, resulting in altered formulations that can cause adverse reactions when applied to the hair or scalp. These reactions may manifest as dryness, brittleness, or an increase in scalp sensitivity, leading to irritation or allergic reactions.

In contrast, the other options suggest positive effects or neutrality, which do not align with the realities of using expired products. Improved hair texture and enhanced fragrance are unlikely outcomes because expired products may lose their efficacy and pleasant scent, respectively. Similarly, experiencing no noticeable effect might seem plausible, but it overlooks the potential for harm when the product's components break down or become ineffective. Thus, the most accurate consequence of using expired hair products is indeed the risk of hair damage or irritation.
