The hair on the scalp is born, has a root through which feeds and a stem (the hair), which grows out of the scalp. Under the scalp the hair bulb is a bulge where the roots penetrate up to five millimeters deep. The bulb is connected with the disc thermal-vital part of hair that works for 24 hours, one or more sebaceous glands and erector. Blood vessels reach the papilla, the link between the hair and the rest of the body, through which it receives oxygen and nourishment. The stem consists of three concentric layers:

• The cuticle
It is the outermost layer and plays a protective role.
This consists of layers of cells and flat corneas, ranging from three to ten layers, superimposed on one another in the form of flakes.

• The cortex
Is the layer that contains 75% of hair, and where is the keratin and melanin.
Keratin is a fibrous protein produced by the root, which depends on the texture and appearance of hair. Melanin is the pigment that gives color to hair.

• The Meulen
It is the center of the stem and is made up of dead cells.

THE LIFE CYCLE OF HAIR

The hair plays in all people and all ages the life cycle: birth, growth and death. When hair is healthy, and 85% is growing, while the remaining 15% is detached. So it is normal to lose between 30 and 60 daily hair fibers. The hair growth is 1 to 1.5 cm. Per month and more rapidly from fifteen to thirty years. His fall or dislodgement increases in autumn and spring.
