What common ingredients should clients with allergies avoid in tanning products?

Clients with allergies should specifically avoid fragrances and dyes in tanning products due to the high likelihood of these ingredients causing allergic reactions. Fragrances are often included in products for their scent but can trigger sensitivities or allergies, leading to skin irritation, rashes, or other adverse reactions. Dyes, which are used to give products appealing colors, can also lead to similar issues, as many synthetic dyes are known allergens.

In contrast, other ingredients such as moisturizers, natural oils, and Vitamin E are generally considered beneficial and less likely to cause allergic reactions. While it is possible for some individuals to be sensitive to natural oils or Vitamin E, these ingredients are mostly safe and often have soothing and skin-benefitting properties. Therefore, the primary concern for allergy-prone clients lies with fragrances and dyes.
