What causes human hair loss?
An average person has 125,000 hairs. We lose about 70 hairs a day. During the changes of season, during the passage in spring or in the fall, one can have up to 180 hairs which fall daily. The hair is therefore renewed the most during these seasonal transitions.
Hair loss is considered to be pathological when a person loses more than 100 hairs each day over an extended period of time. It is then necessary to make an examination which is called trichogram. It involves taking hair from various areas of the scalp to observe it under a microscope. In women, a hormonal check-up can be done in certain cases. This recurring hair loss is called alopecia.
Genetic reason.
The most common reason is hereditary androgenetic alopecia. The person then has the volume of the hair which decreases gradually, with sometimes baldness. This affects 30% of young men (under 30) and 70% of all men (in their lifetime). This hair loss generally occurs around 20 years of age; it stabilizes around 30 years. It is the influence of male hormones (especially dihydrotestosterone) that will be responsible for hair loss.
According to the latest studies, the stem cells present in the hair follicle become inactive, causing the atrophy of the hair follicle which generates more than microscopic hair. Before the top of the head is reached, it will first go through the temples.
Stress.
Acute hair loss happens when the person is the victim of a traumatic event, psychically or physically. It can be intense stress from work, school, bullying, or physical harassment. It can come from drug treatment, chemotherapy, nutritional deficiencies, lack of iron, hormonal disturbances, significant radiation.
To combat stress, in addition to physical activity, it is often recommended to take herbal supplements, such as ginseng
or rhodiole which boost, among other things, the energy of the organism.
If you have a low level of iron, zinc or vitamins, the simplest is to opt for multivitamin food supplements, which often have magnesium, B vitamins. Propolis is also known to increase intellectual and physical performance .
Localized hair loss.
Localized and atypical hair loss occurs after a burn, alopecia areata, tumor, parasites such as lichen, ringworm; or even after radiotherapy.
Congenital.
This may be the result of congenital alopecia. That is to say following a malformation that appeared in utero, during pregnancy.
Autoimmune.
Hair loss called "areata" is an autoimmune alopecia. Hair is absent in several places of the skull. This can affect the entire scalp, so we talk about "totalalis" alopecia, or even the whole body ("universalis" alopecia).
Do not hesitate to consult a dermatologist for the advice of a health professional.
