Hair loss in children

Just as with adults, many different causes can lead to hair loss in children. Almost always the hair grows back completely, often without treatment. A rare cause can be genetic diseases.

However, in these cases, other, more serious symptoms usually predominate, so that hair loss is secondary. More frequent is an infection of the scalp, the so-called tinea capitis. The fungal pathogen causes dandruff on the scalp.

Typically, the hair then breaks off on reddened areas. Possible causes are close contact with animals or living in rural areas. This type of hair loss is completely reversible with the application of anti-fungal ointments or tablets.

Another type of hair loss that is usually completely reversible is circular hair loss. The most likely cause is a malfunction of the immune system, which is directed against the hair-forming cells. In most cases, the bald spots recede within half a year.

However, a recurrence is possible. Cortisone preparations, which are applied to the bald spots, ensure a faster regression. Stress or psychological strain also have an effect on children’s hair. The phenomenon of self-inflicted hair pulling was also observed in children.

Hair loss and thyroid gland

The hormones of the thyroid gland act on many different tissues and cells in the human body. Among other things also on the hair-forming cells. Normally, the hormones ensure that the hairs on the one hand form new hairs and on the other hand survive for a certain time in a stable way.

If the hormone balance is disturbed by a disorder, this can result in hair loss. It is not important whether the thyroid gland tissue is overactive or underactive, because too much or too little hormone can lead to hair loss. For a clinical difference, the accompanying symptoms are groundbreaking.

In the case of hyperthyroidism, the hair is rather greasy and thin, and heart palpitations, anxiety attacks, diarrhoea and many other symptoms can also occur. In contrast, hypothyroidism is characterized by dull, brittle hair, freezing, tiredness, depression and constipation. The family doctor can make a reliable distinction by checking the thyroid hormones in the blood. When the balance of hormones is restored, the symptoms, which include hair loss, are slowly and usually disappear completely.
