Precautions while using Shampoo
Gluten free or wheat free
Many people suffer from eczema on their palms and their head. Some find that wheat or gluten (the protein found in many grains including wheat) is the cause, particularly if they are sensitive to this in food; e.g. celiac disease wheat allergy. Shampoo can often go into the mouth, particularly for children, so all individuals who are on gluten free diets may prefer to find a gluten free shampoo. Shampoo manufacturers are starting to recognize this and there are now gluten free and wheat free products available.
