How Aging Affects Your Hair
The hairs you see on your head are actually made up of dead cells that emerge from the hair follicle implanted within the outer layers of skin, known as the epidermis and dermis.1 Each strand is made of a protein called keratin and surrounded by an outer layer of overlapping scales called the cuticle.2
Hair aging can be caused by genetic, biochemical, and hormonal changes to the hair follicle as well as environmental “wear-and-tear” to the hair itself. Good hair care can minimize some of these changes, while certain treatments can conceal damage you’d rather others not see.3
