Therefore, hair is the decoration of women and the height of men’s youth. The hair on the human beauty, so some people worry when their hair begins to fall, but do not worry about hair loss is normal;
Studies have shown that hair loss at 100 hair per day is normal.
Hair loss is different for women and men due to gender differences. The rate of hair loss also varies between those who have given birth to new children and those who did not have different hormones in both cases. Human hair consists of keratin, a special protein that is also responsible for the formation of fingernails and hands. The human hair is an important part of its skin. It is produced by the so-called root cells. The hair is about 100,000 hairs, and its thickness varies according to gender. .
Stages of hair growth
The hair undergoes three stages: growth (Anagen), Catagen (Catagen), and Telogen. The following is a simplified explanation of each stage:
Growth stage
At this stage hair cells are divided very quickly increases the length and intensity of hair, and extends this stage from two to six years, and in other sources from two to eight years depending on the genes of the person, and at any time the proportion of hair that goes through this phase of growth Between 80% and 90%, and there are some people long hair their head very quickly because the growth period have a long period, and others note that the hair does not go much long or it lengthens very slowly depending on the short stage of growth and have at the end of this stage, To the next stage.
There are some factors that reduce the duration of the growth stage, for example, the period of growth period is short in people who follow a diet diet in which the food is very limited, and suffer from the subject of chemotherapy, or newly born, and because of short Growth stage A large amount of hair falls into the stage of falling. One notices that his hair is falling in large quantities. Some people suffer from short growth stage and do not have to cut their hair from time to time. It does not go on for unknown reasons, and this is rare.
Transitional phase
At this point, the hair moves from the growth stage to the stage of stillness and stability. This phase is called transitional because blood is cut off from the hair follicles, thus the food supply stops and the hair stops growing. It gradually shrinks to one sixth of its original length, which ends but does not fall. From two weeks to three weeks and a maximum of four weeks.
Sleep phase
At this stage the hair enters the state of stillness and remains until the stage of growth begins again and the hair falls damaged, and 10% – 15% of the hair at this stage at the same time, and continue this stage of two to four months, New hair loss occurs when the growth stage and grow new bristles and push hair damaged to fall, and the rate of hair loss of 50 to 100 hair per day, it should be noted that the hair is full does not pass at the same stage at the same time, does not drop human hair once and becomes Bald to begin the growth of hair again in the growth stage, but passes through part of the hair Growth phase and another part in the transitional stage, while a third part in the sleep stage, and so on.
Hair components
The hair consists of two main parts:
- Root: The hair follicle, which is part of the live hair, which the blood vessels supply to the food. In each root, there is a fatty gland that releases a substance responsible for arranging the hair, and this fatty material works to protect the hair by wrapping it in a casing Thin protects him.
- the trunk: Is the visible part of the hair, and consists of a group of thin fibers surrounded by a layer of horn made up of keratin produced by the cells inside the bulb, and protects this layer of hair from external factors, and is affected by many things such as: used shampoo, hair drying tool, hair dyes Different.
Causes of hair loss frequently
The loss of 50 to 100 hairs a day is a natural condition, as mentioned earlier, as it is part of the hair regeneration and growth stages. There are some permanent causes of hair loss, such as exposure to chemotherapy or radiation, or thyroid dysfunction. Temporary and common like:
Hormonal causes
Hormone change affects the rate of hair loss in men and women, often associated with Androgen hormone and dihydrotestosterone. They affect hair follicles. The production of these hormones is linked to human genetic genes. Women lose too much hair after birth. From three to six months, due to the change in hormones in women, and the factors that cause the change of hormones also take women pills.
Causes satisfactory
Hair follicles are sensitive to a large extent and are affected by some of the imbalances that occur in the human body and cause the disease, but they quickly return to normal in the case of healing, and these imbalances rise in the temperature of the body, which falls heavily after a month to three months And the activity of the thyroid gland or its depletion will negatively affect the rate of hair loss in the patient, and contribute to malnutrition in the increase of hair loss, especially the lack of the treatment of proteins important for hair regeneration and maintenance, and chemotherapy and radiation therapy such as cancer treatment of Most important Factors leading to hair loss, is also taking prescription drugs that do not act only by prescription is another factor of factors such as increased hair loss drugs gout and arthritis.
Vesicular disease is a serious disease if not treated and reduce its spread; not only the fall of hair head, but extends to the eyelashes and eyebrows, usually confined to fall part of the head area, and affect the stress and psychological pressure on the amount of hair falling, The human body affects the hair loss, so the individual must compensate for the lack of iron to take the necessary treatment, and some studies indicate that hair transplantation may affect the future of the negative and lead to an increase in the rate of hair loss.
Cosmetic reasons
The use of non-suitable cosmetic materials for hair is one of the factors affecting the hair negatively, such as: the use of bad dyes or curling or softening materials, or the treatment of chemicals in a wrong way and harmful to the hair, or the repetition of chemical treatment; the repetition makes it weak and damaged, It is preferred to comb the hair a few times a day and using a soft hair brush, and should be dried after bathing by gently squeezing it without rubbing it strongly, and advised hair styling It does not require much intensity because it will lead to a lot of fall, especially in the area of aspects.
