What should clients avoid before tanning to maximize results?

Clients should avoid exfoliating the skin or using products with heavy fragrances before tanning to maximize results because such actions can affect the skin's natural barrier and alter the tanning process. Exfoliating can remove dead skin cells, which might seem beneficial for allowing the tan to develop evenly; however, it can also lead to uneven tanning results or increased sensitivity to UV exposure. Additionally, products with heavy fragrances can contain chemicals that might react poorly with tanning agents, potentially resulting in an undesirable tan or skin irritation.

In contrast, while excessive moisturization may not be ideal just before tanning, clients are generally encouraged to keep their skin hydrated. Wearing tight clothing could hinder the tanning process by causing uneven tan lines or irritation, and while caffeine consumption may affect general skin sensitivity, it does not have a significant direct impact on the tanning results like the other factors mentioned. Thus, avoiding exfoliation and heavy fragrances is crucial for achieving a smooth and long-lasting tan.
