Keratin acts both as an external protective protein in the cuticle (the outer layers of a hair strand) and as an internal structural protein in the cortex (the inner core of the hair that helps determine its strength).
Keratin is depleted when hair is damaged physically, chemically and/or from environmental factors, such as the sun.
