Hair loss often for no reason, when will it become a disease?

What is pathological hair loss?

Normally, each hair can live about 8 months to 5 years. So, in a life cycle, hair will gradually age, weaken and fall is normal.

A healthy person can lose between 50 and 100 hairs per day. After hair loss, a new amount of hair will be grown to replace, compensate for the number of hairs that have been lost to ensure a stable thickness for the hair.

However, when the amount of hair loss is more than 100 hairs/day, it is called alopecia areata. Identify pathological hair loss by some symptoms such as:

– Losing a lot of hair (over 100 strands/day), especially when shampooing, waking up and when brushing and combing hair, the amount of hair attached to it is more than usual.

– When my hair grows, it will grow weak, thin, curly or even no hair

– Thin, sparse hair can clearly see the scalp in women.

Hair falls out in patches, which can cause mild male pattern baldness.

Diseases that cause hair loss

Cancer patients lose their hair during chemotherapy

Hair loss has become an obsession for many cancer patients, especially women. However, patients should not be too worried because usually the hair will grow back about 1 to 3 months after the treatment ends. At this time the hair may change in hair color or hair structure such as becoming more curly; or thin. And after about 6 months – 1 year the hair will return to normal.

Thyroid disease

Thyroid disease causes an imbalance of thyroid hormones in the body. Hypothyroidism causes decreased hormone levels, underactive thyroid gland; Or hyperthyroidism, the body produces too much hormone, the thyroid gland is overactive.

Hair loss is one of the typical signs of thyroid disease. When the amount of thyroid hormone is out of balance, it will interfere with the metabolism, leading to many inactive hair follicles, from which hair grows less and becomes thinner.

Inflammatory disease of the scalp

The hair fungus parasitic on the dead cells of the hair and they easily spread to the entire scalp. Leads to various types of scalp inflammation, infection …. makes hair thinning, easy to fall out. If ringworm is not treated, it can cause large patches of hair loss and can lead to baldness.

Immune system disorder (autoimmune disease)

When the immune system is disturbed, the body may mistake hair follicles for foreign invaders, leading to the body forming antibodies to eliminate hair follicle cells. In particular, the hair germ cells are damaged, leading to the process of hair loss coming faster and earlier than usual.

Polycystic ovary syndrome

In women, polycystic ovary syndrome causes a hormone imbalance that causes the body to produce too many male hormones instead of female hormones. This disease often causes a lot of hair loss, while hair on the face and other parts of the body grows more than necessary.

Insomnia is one of the causes of hair loss

Anemia, lack of substance

The process of growing hair consumes a lot of nutrients to have a strong hair, while in women, it is easy to lack blood and important nutrients such as zinc, protein, iron … due to menstruation, pregnancy , childbirth or inadequate meals. When the nutritional content is inadequate, the hair germ cells are deprived of nourishment, lack of vitality, weak hair growth and easier to fall out than usual.

Losing too much sleep

Insomnia can cause many health problems, including hair loss. A full night’s sleep is an opportunity for the body to rest, eliminate toxins, repair damage and regenerate energy.

Stress

Stress is also one of the causes of hair loss. Stress affects the nervous system, immune system and causes other disordered reactions in the body. It can also shorten the hair growth cycle and lead to hair loss.
