Structure and physiology of hairEvery woman wants to have beautiful and healthy hair, but she has to be very aware of the structure of her hair and hair in general before undergoing any beauty procedures that are most damaging to her, be it at home or in the hair salon.
Even if you are not yet dying of a common culture, you need to know and know what you are doing on your hair.
You should know that hair does not have the ability to recover itself. The fact that we do not feel pain when we cut, bleach, curl or dry at high temperature with a press and a hairdryer does not mean that we do not cause stress.
So my advice is as rare as doing this at home with a girlfriend and trusting professionals in this area.
The hair consists of two parts:
Root - found in the dermis.
Stem - goes over the surface of the skin.
The root is located inside the skin and is wrapped in a hair follicle bag.
The root of the hair ends with a thickening - a hairy bulb.
Above the surface of the skin is the stem of the hair.
The follicle joins with the hair muscles.
And in the epidermis is its base, called a hairy bag.
Bundles of smooth-muscle fibers are attached to the hair bags, which are responsible for the movement of the hair.
At their contraction, the hairs face the skin.
Interestingly, it is shortened as a result of emotions.
Here comes the popular expression
"My hair is bristling."
The stem of the hair is covered by an outer layer - the cuticle. This is the protective sheath of the hair. It consists of horns (flakes that are 7 to 11 layers) arranged as tiles. If the horns are firmly attached to the hair, it is smooth and brilliant. In order not to remove the horns from the hair, it is important to wash the hair with appropriate hair type products as well as the washing method. This topic will be touched on in another article, as it is very important and often overlooked.
Beneath the outer layer is the pigment - melanin. It gives the color of hair. Interesting is the fact that melanin is contained in the iris of man's eyes, where we can determine whether the hot or cold pigment predominates, which is very important in the choice of paint (there are exceptions).
In the case of chemical waving and dyeing, this layer is exposed to chemicals, where the melanin reacts with alkali or acid. I will give you an example to make it more clear what hair is going through.
For example, if a permanent curling of hair is done, the curl is a highly alkaline product, and the fixation is acidic. Which means we first open the curly hair, and after 10-20 minutes of curling, we close it with the fixation. Exactly this opening and closing can seriously damage the hair. Today on the Bulgarian market there are both nocturnal hair dyes and unmoved curls that pretty much spare hair, but these procedures must nevertheless be performed by a professional in this field.
With the age in the hair increases the air bubble content and reduces the amount of melanin. As a result, the hair darkens or lightens and turns gray.
The core of the hair - the brain layer - is made up of completely incomplete round cells.
The hair may "rise". The volume is increased by 10-20%.
The hair lives from 5 to 15 years, and sometimes longer. Hair may fall off. Instead of them, the hair bed can grow new.
Hair loss occurs in diseases, stress, infections, irradiation. Sometimes hair loss depends on heredity or hormonal changes in the body.
Each hair has a life cycle that consists of 3 phases:
Facts about the hair cycle
The condition of the scalp hair in a different cycle is:
1. Anagen - growth phase - formation and growth of the hair 85 - 90%.
2. Catagen - transition phase - growth in hair bulb decreases and slows down <1%.
3. Tylogene - a phase of rest - the hair stops growing, its bulb comes to the surface of the scalp and the hair falls 10 - 15%.
Telogen effluvium (hair loss)
Hair loss due to teflon effluvium:
Characterization and morphology of telogen hair Solid, thick, dry white matter in the hair root region.
Thinning of the hair is never lost completely.
It affects the scalp but in more severe cases it can affect eyebrows or intimate areas.
Telogen effluvium is a completely reversible form of hair loss.
There are three main mechanisms under which a teled effluvium can develop.
1. Impact of environmental factors, which causes the passage of the fecal hair into a resting phase - telogen.
2. Slow and gradual development of a tellurium effluvium that lasts for a long time.
3. The hair follicles go through shortened hair cycles without leaving for a long period of rest. This results in thinning of the hair and the continuous fall of thin and short hair.
What are the reasons for a tegumentary effluvium?
After birth, a sudden change in hormone levels at birth.
After vaccination, severe diets, physical trauma (after a car crash, surgery)
Accepts some drugs - antidepressants
The effects of toxins
A heavy diet
Change in diet
Deficiency of iron, zinc, amino acid L-lysine, vitamins B6 / B12
Now you are familiar with the hair styling and all you have to do is find your stylist, colorist or, in a word, your Hairdresser.
