Introduction

With different colors, styles and variations, young or mature, male or female, the hair has an important role in a person's image.

While advertising for products that "strengthen the hair" are almost always male-oriented, it may seem that women do not suffer from alopecia. The reality is that over two thirds of women face the challenges of hair-loss at some point in their lives.

Many women find this very disturbing, perhaps more than men. In addition, the female physiology is unique, and factors such as menstrual cycles, pregnancy and menopause are particularly important.

For some women, hair loss can be genetic; however, many of the causes of female hair loss are treatable.

Without a doubt, the physical appearance of women depends greatly on their hair. For many women, their hair is a sign of youth and vitality.

Hair structure:

The external portion of the hair, called the stem, is the part of the hair that we see and style. In reality it is dead tissue produced by hair follicles, small bag-shaped structures located deep in the scalp. Each hair is enclosed within a follicle.

The average head has 100,000 hairs. At the base of the follicle is the oval shaped root, which is responsible for the growth of hair. In the lower portion of this is the papilla, which contains blood capillaries that provide blood to each hair.

As hair grows, the cells move towards the surface of the skin and become a protein called keratin, being replaced by new cells. Keratin is the same protein found in the nails.

The stem is composed of 3 layers: the cuticle, the cortex and medulla. The cuticle, or outer layer, consists of small cells known as scales. The cuticle serves as a case for the cortex, the thickest portion of the stem, composed of cells arranged in the form of tobacco leaves. The cortex holds the pigment that gives hair its color. The medulla is composed of cells with the form of a case and is located in the center. The spaces between cells in the medulla influence the refraction of light in tone and hair.

Glands and muscles

The hair is lubricated by oily secretions from the sebaceous glands, located on the sides of most follicles. Surrounding these glands and the rest of the follicle, there are groups of muscles (arrector pili) that allow the hair to stand up when a person is cold or
