Hair has two parts: the root and the stem.
root under the skin to the hair follicle and the stem - on the skin surface, this is what we see.Extended part of the root called hair follicles or follicle.From the shape of the follicle it depends on the shape of the rod.
People have different number of hair follicles, this is due to hereditary characteristics and laid at the genetic level.At the root is the depth of the dermal papilla, connected to blood vessels and nerves, it is responsible for hair nourishment.Papilla - the most important part: if he dies, this place does not grow new hair.To him fit sebaceous glands that produce fatty grease, which makes hair shine.Lubrication helps to retain moisture, it adds to the hair surface elasticity.St
hair shaft consists of three layers: the outer (cuticle), cortical (cortex) and medullary (medulla).For proper growth of the rod meet the muscles that raise the hair.
cuticle performs a protective function, it is formed by 6-10 layers of keratinized scales.On how tightly they are adjacent to each other, it depends on the appearance of hair.Under the influence of the alkaline environment flakes shampoo disclosed, and closed in an acidic medium rinses.With frequent staining the cuticle is destroyed, the hair becomes thinner and become brittle.
Cortex - cortex, gives hair flexibility and elasticity.In its structure there is melanin or coloring pigment responsible for hair color.Melanin is of three colors: yellow, black and red.Their combination provides a variety of hues.

cycles of hair with age is slowing.
hair vary in shape and cross-section.For example, straight hair have a circular cross section and one stem.Wavy hair - an oval cross-section and a few bars, and the shape of curly hair reminiscent of a kidney section.
Curled hair also has in its structure a few bars.
