A contraindication for hair coloring refers to a situation or condition that prevents a client from safely undergoing the hair coloring process. In the context of this question, a history of allergic reactions to hair dye is a significant concern. Clients who have previously experienced allergic reactions may face serious health risks if exposed to hair dyes that contain the same or similar chemicals. This situation necessitates caution and often a complete avoidance of hair coloring procedures to ensure the client’s safety.

Other options, such as a client preferring a lighter hair color or having dry hair, do not inherently pose a health risk and can often be addressed with appropriate techniques or products. Similarly, a client's desire to change their color frequently does not constitute a contraindication; it simply reflects their preferences which can be managed within the scope of professional practice.
