What a hair


Unknown animal world, the hair belongs only to man! this hair very individual is located on the top of the skull in well-defined limits. shaped like a half made visible, stem, and root beneath the skin, the hair bulb-ca, it is born, grows and dies in a process ring (Fig. 1).

- A complex composition

true "plant" the hair bulb is the seat of a

Intense activity acellular made of chemical and biological constant. It provides a hair that grows from its root about 1 to1, 5 cm per month. His life, genetically programmed, is 3 to 5 years in men and from 5 to 7 years in women.

Each hair loss treatment is permanently lubricated by one or more sebaceous glands. Sebum secreted assures brightness, resistance and flexibility.

The stem treatment drop hair consists of three parts. Central marrow, or spinal canal, is composed of cells surrounded welded together by an intercellular cement of the real. Finally, the cuticle just wrap and protect the cortex by cells arranged in a biologically inert scales, their free edge being oriented toward the tip of the hair (Figure 2).

The hair counts An adult has an average of 100,000 to 150,000 hair. Density of 200 to 300 per cm2 by area of the scalp, its maximum being located at the crown Hippocratic . In children, this density is doubled, tripled see ... the leather surface hair is about 600cm. Growth is 1 to 1.5 cm month it slowed down during the night , also follows a seasonal rhythm. It is larger in summer than winter, because the sun encourages growth. A single hair can support a mass of 100 lines. Very elastic, it can also lengthen 1.5. According to its importance, hair weighs between 50 and 200 grams .

The analysis performed by electron microscopy showed the extreme complexity and precision of the organization of the stem cells make the hair strong as a twisted cable.

To make hair and use a better method for hair loss treatment the root absorbs and uses elements carried by the blood vessels: Oglio minerals and elements, vitamins, amino acids, hormones and other substances are well processed continuously.

final color of the hair is fixed dice his birth at the hair bulb. Special cells produce a pigment called melanin. The truth of infinite colors hair visible at the upper cortex and di is the result of this pigment own good mix to each person.

- The hair cycle

the body hair appears during 2nd month of fetal life. Although we do not yet know exactly how or why, hair follicles specialize and differentiate into different types of hair.

Some will form the eyelashes, eyebrows, axillary hair, pubic and those distributed throughout the body. However, fly appeared at birth will place in the final coat at the time of puberty.

From the 3rd month, some hair follicles become hair. This silky down called lanugo is replaced from birth to each of them are already identified and these specific features do not vary during the life.

Each hair is independent of the neighbor kid grows in a cycle its own (Figure 3). is why we keep hair homogeneous no.

When the hair informs us Like all body cells, hair cells contain chromosomes in their nuclei as DNA. Their analysis makes it possible to identify a person through his DNA. Chemical analysis of hair is also an important source of information during criminal investigations forensic. Functioning as a '(memory) it can sometimes explain causes of death or reveal valuable clues about the health of an individual. Since the hair is being phased out of certain drugs or toxic substances, it becomes possible, when locating traces of the product on the hair shaft, determine their nature and even the exact time of ingestion. Historians have seen in this particular way of solving some puzzles. The discovery of lead in a strand of hair Ludwig van Beethoven allowed to diagnose a severe poisoning, lead poisoning. This disease was responsible for deafness, and abdominal pain syndrome Depart-SIF he suffered for years. Finally, archaeologists have discovered traces of cocaine in hair a Peruvian mummy dating back 4000 years and were able to say, 3000 years after his death, Ramses was reddish-blond.

mix of ant and balding scalp, unlike animals that moult certain periods. Eighty-five percent of our hair are constantly in a growth phase, while only 10 sonnets fall in line. It is not worrying about losing every day from 50 to 100 hair. The hair cycle occurs in three phases: Phase ana-gene or growth phase is the period during which hair grows 1.5 cm per month (80à90 of treatment drop hair). It lasts 3-5 years. Phase castagne succeeding is marked by a stop growth cheveu.les cells at the depth of the bulb dies, causing a retraction the follicle toward the surface of the scalp. This phase lasts 2à3 weeks (1% of hair ).

At the telegenic phase or period of rest of the hair, the hair sentenced (1 in 10) falls spontaneously when styling or shampoo. He was replaced by another after a while. The age, sex or genetic predisposition of each of us, have a significant influence on: the duration of the different phases of the hair cycle, the proportion treatment of hair loss phases of growth and those destined to fall. For reasons related to genetics and hormones we secrete at puberty, it happens this cycle will change and goes wrong.

Good to know for a good hair loss treatment Cut the tips of the hair a moonlit night, n ' has no effect on growth or on the Vita-ity, as it grows from its roots just under the skin. Similarly, the frequency of shampoo or wearing a helmet hastens not hair loss since it - is genetically programmed. We lose more hair in autumn and to a lesser extent spring.
