Structurally the scalp is identical to the skin tissue located
throughout the body except it also contains about 100,000 hair follicles
that give rise to hair. Actually the hair and the hair follicle are a
derivative of skin tissue. There are two distinctive skin layers, one,
the epidermis (outer layer) which gives rise to the protective shield of
the body and the other, the dermal layer (deep layer) which makes up
the bulk of the skin and is where the hair follicle is located. This
dermal layer is composed of connective tissue and the connective tissue,
with its gelatinous fluid like characteristics provides support,
nourishes and hydrates the deep layers of the scalp. The result is
healthy lustrous hair and a moisturized scalp. Again, all of this is
made possible because of the presence of HA in the scalp tissue and its
ability to form this fluid and hold water.
