Hair as your decoration.


Hair main role is decorative. For many people nice looking hair is so important that the slightest change in their volume, color, structure or arrangement is a reason to see the doctor. Hair illnesses are in most of the limes connected with skin and nails illnesses.

We have about 100 000 of hair follicles on our heads. Every follicle can grow about 20-30 hairs during a lifetime. On an infant skin hair are thicker than on a grown up head.

Primarily hair ovules appear in the 9th week of a foetus life. First, fully grow hair are grown between 5 and 6 month of foetus life (lanugo). The foetus looses them during 7 to 8 month. They are being replaced with terminal hair. After the birth, new hair ovules are being grown.

Fully grow hair consist of three things: a hair root which Is in the skin, a haft which is also called a hair stalk and a hair end, which has a sharp ending and it can occur when the hair are not cut. The hair root is placed in hair ovule, from where the sebaceous leaves. The root in its lower part is getting wider creating a bulb, which contains the hair papilla. If the hair papilla is destroyed, the permanent loss of hair occurs. The hair grows from the skin under a certain angle. On the obtuse angle side the hair side muscle. On the cross section on the skin the hair has a laser structure. There are four basic layers; each layer is built from few other layers. Looking from the inside we can see the exact hair, the inside sheath of the hair and the hair follicle. The exact hair, growing from the skin, is built from the cord layer, which is not present in some of hair follicle, a core and hair shield. The shield is build from scales, which overlay on each other in a tile way, what looks like a pinecone.
The main chemical substance of the hair is keratin. In opposite to the keratin in Horny layer of the skin, the hair keratin consists of 20% of cisterns, an amino acid very rich in sulfur. The keratin particles have many bonds, thanks to which, hair have a steady structure, as well mechanic as chemical. We can divide hair in three kinds: Primary (lanugo), boomy and terminal. The last ones are long hair (hairy skin on the head), Bristle hair (eyebrows and lashes), the hair of the armpit and gender area. Hairs react differently to androgenic hormones. Due to that they are being divided to three groups. First of them are hair depended on the gender, those responding to androgens, but only in concentrations which occur only in men's body. Those are beard hair and between gender triangle and umbilicus, as well as in outsider ear. The other group is so called ambisexual hair. They are also dependant on androgens, but in concentrations typical for men and women. They include the gender area and armpit hair. The third group is hair independent from the gender, which do not react to androgens. Those are eyebrows, eyelashes. The most important androgen is testosterone. In the place of its activity, which is the matrix of the hair, under the influence of 5 alpha reductase enzymes, it is being converted to dihyderotestosteron.
Human hair has its own growing cycle, independent from other neighboring hair. This cycle is divided to three phases: antigenic phase, the growth phase, katagenic phase, which is the transitory phase and telogenic phase, which is the resting phase. Normally on a hairy head there an 85% of androgenic hair, less the 1 % of katagenic and 15 % of telogenic hair. The androgenic phase can last for example on the head for 2 to 6 years. The katagenic phase lasts only for few days. During this phase the hair stops to grow. The telogenic phase, at the end of which the hair starts to fall out, lasts approximately about 3 - 4 months.
Even though the structure is so permanent and complicated, the mechanical destruction can occur. It can be caused by over vigorous brushing or combing. In this case the shield of the hair is being destroyed, and even the deeper parts of the hair. Especially curly hair are exposed to that. Excessive washing can causes dryness and frailness, although when using modern and good shampoos it is not a common occurrence. Perm liquids can disturb the hair structure. Some hair colorants can change the color of the hair in a more permanent way and damage them. Some perpetrates for hair brightening, peroxidating the melanin in the hair, weaken them.

A.T.W. Aztec Gold series contain the shampoo and the moisturizer. The shampoo containing washing vegetable substances, coming from coconut palm and corn, has great washing properties. It also does not dry the skin on the head and the hair, giving them the gloss and it optically increases the volume. As well as in the shampoo the moisturizer contains Aztec herb extractions. This herb contain vegetable fitohormones, so called fitoestrogenes, as well as microelements (aluminum, cobalt, iron, magnesium, zinc, silicon, selenium)and macro elements (calcium, magnesium, potassium, sodium, phosphorus), saponines, a lot ofprovitamines, vitamins (beta carotene, niacin, thiamine, vitamin B2 and C), proteins and carbohydrates. This causes the nutrition of the hair from its basis, influencing the hair bulb itself. Because of that the moisturizer is recommended for dry and damaged hair, e.g. with coloring. It makes the hair bulbs stronger, improves the structure and the look of the hair. The moisturizer also helps with hair styling, because special starch extract is added. What should be underlined is that the cosmetics have very serious nutrition properties and should be used.
