High salt content has severe negative effects on the health of the hair. It dehydrates the body. Hence preventing hair follicles from getting the moisture needed for proper growth. Also, the presence of high salt content can deprive the body of valuable nutrients. This is because it prevents the absorption of nutrients through hair follicles. According to the U.
