Care of the hair and care of the scalp skin may appear separate, but are
actually intertwined because hair grows from beneath the skin. The
living parts of hair (hair follicle, hair root, root sheath and
sebaceous gland) are beneath the skin, while the actual hair shaft which
emerges (the cuticle which covers the cortex and medulla) has no living

repaired by a biological process, though much can be done to manage hair
and ensure that the cuticle remains intact.
Scalp skin, just like any other skin on the body, must be kept
healthy to ensure a healthy body and healthy hair production. If the
scalp is not cleaned regularly, by the removal of dead skin cells,
toxins released through the skin or external hazards (such as bacteria,
viruses, and chemicals) may create a breeding ground for infection.
However, not all scalp disorders are a result of bacterial infections.
Some arise inexplicably, and often only the symptoms can be treated for
management of the condition (such as dandruff).
