Hair loss, main causes

Abnormal hair loss
There are multiple causes of hair loss. Often, abnormal hair loss is mainly due to some important factors such as heredity, hormones, stress, poor techniques  or products, diseases and infections of hair. The first thing to establish is : is this  hair loss normal or abnormal. Indeed, the telogen phase is the last part of the hair life cycle, it is the resting phase of hair follicle.

Heredity

The genetics plays an important role in the early hair loss problems. Indeed, during the formation of the embryo in the woman's body, scalp surface is formed from the genes of both parents. When the mother is affected by baldness or important hair loss, the risk for the child to be suffering from hair problems is multiplied by 10. In addition, when the two parents are affected by baldness, the risk is greater than 90%, while the risk is a little more than 80% if one parent is affected by two grandparents. It is strongly recommended to perform hair analysis and to provide hair care as soon as possible.

Malformations and scalp problems

Some malformations of the scalp can cause hair problems. For example, the aplasia cutis of the scalp as well as ectodermal dysplasia can lead to the complete absence of hair or the appearance of very fine hair and fragile; these syndromes or malformations can therefore lead to several problems of hair loss and baldness.

The Adams-Oliver syndrome is a rare disorder characterized by the association of congenital anomalies of body parts and scalp, often accompanied by defects in skull ossification.

Hormones

Hormonal changes probably play the biggest role in the development of abnormal hair loss. For men, testosterone is transformed into dihydrotestosterone in a too high concentration often leading androgenic hair loss. For women, pregnancy and menopause bring important hormone changes and therefore lead to more positive or negative changes in the hair apparence. The main hormone that transforms women hair is estrogen, which in larger quantities, improves the condition of hair and volume while a decrease causes a major hair loss. During aging, the man body as the woman body tend to decrease its production of hormones. This reduction, in addition to the fact that hair follicles lose their force, can lead to less healthy hair and to premature hair fall.

Stress

Bodily fatigue, overwork and stress over long periods increases the risk of hair loss. An emotional or physical shock, such as traumatic events also lead to immediate upheaval that affects the health of your hair. The volume of hair is usually directly affected by the stress;  part of the scalp are visible to the naked eye or using instruments to measure the density of your hair. Stress is a cause of alopecia.

Chemotherapy

Chemotherapy makes your sensitive scalp and sometimes causes hair loss. This hair loss is mostly temporary and with proper care, you will recover your hair quickly.

Dandruff

The itchy scalp often leads to scales that are often observed under the form of dry dandruff, falling from the scalp. In other circumstances, oily dandruff can also make their appearance on the scalp, thereby increasing the risk of hair loss by smothering the hair follicle.

Side effects of drugs

The drugs must be taken appropriately. Side effects may cause injury or infections of the scalp. In all cases, it is best to read the package leaflet before the treatment. Some side effects may accelerate hair loss or cause other problems with your scalp.

Nutritional deficiency (iron deficiency or vitamin)

A deficiency or poor diet can lead to imbalances of  the scalp and whole body. It is well known that poor diet increases the risk of obesity and all other related problems. However, health problems or hair loss can also be related to a lack of vitamins or minerals in the body. During a dietary deficiency, the hair follicles are not properly fed through the scalp, which can accelerate hair loss.

Parasites, diseases and scalp

Certain systemic diseases, parasites or other dermatological diseases and disorders of the scalp, as well as lesions that lead to scars, can worsen the health of the skin or cause blockages to the growing hair. Among the well known diseases, we find: dandruff, seborrheic dermatitis of the scalp, pityriasis, alopecia areata, scalp psoriasis, ringworm, scabies, head louse (lice) , Lupus, Scleroderma and Trichotillomania.
