What is the reason for hair falling out in clumps? Is it alopecia areata?

Generally, hair loss in clumps is likely caused by alopecia areata. The cause of alopecia areata has not been clearly identified at present, but it may be related to the patient's mental reasons, genetics, infectious diseases, etc. You can seek medical treatment and control the disease.

1. Psychoneural factors of alopecia areata:

Dermatology expert groups have repeatedly confirmed in clinical practice that many patients have a history of neuropsychiatric trauma before developing alopecia areata. There are various types of mental trauma, such as: sudden fright, death of loved ones, setbacks in love or career, or blunt head trauma, etc., and alopecia areata will appear shortly thereafter. Once the psychoneurological factors are eliminated, the disease is easier to cure. But what cannot be explained is why some people lose their hair with just the slightest stimulation, while others do not develop alopecia areata even with much greater stimulation. This shows that in addition to mental factors, alopecia areata may also be caused by internal factors, and mental factors are only the triggering factors.

Medical research has found that patients with hair loss often have more prominent personality traits. More than 41% of patients are introverted and unstable, and more than 70% of patients have sleep disorders such as insomnia, difficulty falling asleep, and early awakening.

2. Genetic factors of alopecia areata: About 10%-20% of alopecia areata cases have a family history, and people with genetic allergic constitution are prone to alopecia areata, which suggests that genetics may be one of the causes. There have been reports of four generations of a family suffering from alopecia areata. This disease may be related to genetic defects.

3. Infection and poisoning factors of alopecia areata: Some patients have infection foci such as tooth decay or tonsillitis, which may be related to alopecia areata, because infections such as bacteria can cause thrombosis in blood vessels or inflammation of small blood vessels, causing hair loss in the area under their control due to obstructed blood supply. Toxic substances can cause hair to fall out, which shows that alopecia areata may also be related to some toxins in the body. Other substances such as fungi, viruses, and external parasites may also be related to this disease.

4. Factors of vascular dysfunction in alopecia areata: 80% of patients with alopecia areata suffer from abnormal cerebral blood flow diagram and poor local blood supply to the scalp. Some people have found that if the skull and scalp are not well matched and the scalp is too tense, resulting in poor blood circulation in the local area, it can also cause hair loss.

5. Endocrine disorders factors of alopecia areata: The incidence of alopecia areata is increased in thyroid diseases, diabetes, vitiligo, scleroderma, and Down syndrome. Alopecia areata is also prone to occur during menopause. Alopecia areata in women during pregnancy often heals itself, but hair loss may recur during childbirth, which is probably related to hormone levels in the body. Therefore, alopecia areata may also be affected by endocrine disorders.
