What are the most common causes of hair loss?

Hair loss is a common ailment that affects an increasing number of women and men. The causes of hair loss are many, from the use of certain medications, hormonal changes, through skin diseases, to stress. In women, the most common causes of hair loss are pregnancy and menopause. Hair can also fall out due to improper diet and hairdressing. Up to 100 hair loss per day is completely normal and means your hair is healthy. If you notice that your hair has more and more hair, don’t panic. First, find out the reason, then try to fight it.

Hormones and hormonal changes

The most common cause of hair loss is hormones – in up to 95% of cases. Hair loss affects women and men (increasingly). These are endocrine problems associated with the main glands that produce thyroid, pituitary, adrenal or sex glands.

Hair often falls out after pregnancy, when there is an estrogen deficiency in the woman’s body. The next cause of hair loss may be discontinuation of birth control pills. Female baldness can also be caused by the sensitivity of hair bulbs to androgens – this usually happens after menopause.

Deficiency of vitamins and minerals

A common cause of hair loss is a lack of iron and zinc in the body. Women are most vulnerable to iron deficiency because they lose it during menstruation and also do not supplement it to the organism with food.

Fatigue and pallor must also be added to the symptoms of iron deficiency. It is not easy to diagnose vitamin A deficiency as a cause of alopecia, but it has a significant impact on the condition of your hair. Supplementing its absence stops the hair loss process.

Another reason for hair loss can also be slimming and malnutrition of the body in terms of amino acids and proteins. A strict dietary regime can sometimes have many side effects, including weakness and hair loss. Taking B vitamins, biotin and amino acids supplements can highly improve your skin state.

Skin diseases

The baldness of the scalp can also cause alopecia. Mushrooms most often get to the scalp when it is injured, or when inflammation forms and develops within the hair follicles.

Hair loss can also be caused by excess sebum (seborrhea). Dandruff, especially greasy, can cause baldness because it sticks to the scalp and hinders the normal functioning of the bellows, which impairs microcirculation. Behind dandruff may be diseases such as psoriasis, eczema and mycosis. To prevent this, specialized anti-dandruff shampoos should be used.

Strong stress can increase hair loss. There are many cases when under the influence of difficult moments in life people affected by stress went completely bald. Stress increases the secretion of hormones such as prolactin, the excess of which causes hair loss. The amount of hair loss is related to the type of stress if it is everyday stress, it weakens the overall condition of the hair, while sudden, very strong stress causes rapid hair loss within a few months.


Toxins are also one of the causes of hair loss. They are exposed to people who deal with chemicals in everyday life. Hair loss can be caused by poisoning with thallium, mercury, boric acid, arsenic and gold. These symptoms do not occur suddenly, as they are long-term effect.

After about 2 weeks in rooms where you can inhale chemicals, all hair falls out. If you have a job where you deal with chemicals every day, it’s best if you use protective masks. Keep the chemicals you keep at home in your cupboards so that your children have little access to them.

If you suspect that you have poisoning with chemicals, which is manifested by malaise, weakness and hair loss, it’s best to go to the hospital. The earlier they diagnose intoxication and give an antidote, the less damage the poison will do.

Smoking tobacco

Smoking is another cause of hair loss. This is because the hair is exposed to harmful substances from tobacco smoke. In addition to hair loss, smoking also has an impact on dulling hair.
