I began using a tea tree shampoo recently after a visit to a health food store. The lady said tea tree and Biotin enriched shampoos would benefit me most, so I went with it. After I got home I read the ingredients and notice wheat or gluten was in the shampoo... I googled it and as long as it's not swallowed I should be good but I have mixed feelings about it containing gluten. Any thought on gluten free shampoos? Has anyone had any experiences: good or bad with tea tree or biotin enriched shampoos or gluten containing shampoos? Just putting it out there,,,,
