How to Put Your Patients on a “Hair Diet”

ABSTRACT The integrity of hair is determined by the intricate building blocks of the many layers of the hair follicle, but it also relies on proper nutrition. Weak hair can result from external factors such as physical trauma, heat manipulation, and chemicals, as well as internal factors such as inadequate nutrition. A “hair diet” addresses both internal and external factors that lead to fragile or damaged hair and provides the basis for a conversation with patients to improve the health of their hair.
