What should be avoided if a client has an allergy to iodine?

If a client has an allergy to iodine, the option that should be avoided is an algae body wrap. This is because many types of algae, particularly seaweed, can contain significant amounts of iodine. When applied to the skin or ingested, they could provoke an allergic reaction in someone who is sensitive to iodine.

On the other hand, clay masks, aromatherapy oils, and herbal steam do not commonly contain iodine as an ingredient. While it is always crucial to check the specific formulations used in these products, they are generally considered safer alternatives for clients with iodine allergies.
