What ingredient should be avoided in products for a client with an iodine allergy?

  1. Seaweed

  2. Algae

  3. Glycerin

  4. Aloe vera

The correct answer is: Algae

The correct choice is based on the fact that algae, which is part of the larger family of marine organisms, can contain iodine. If a client has an iodine allergy, using products that include algae could provoke an allergic reaction because of the potential presence of iodine or iodine derivatives in these ingredients. Seaweed, while similar to algae, specifically refers to various kinds of marine plants, many of which are rich in iodine as well. Therefore, products containing seaweed should also be approached with caution. Glycerin and aloe vera, on the other hand, are not related to iodine and are generally considered safe for individuals with iodine allergies. By understanding the relationship between these ingredients and the allergy, practitioners can make informed decisions regarding the safety of products for clients with specific allergies.
