Analysis of the four major factors that cause seborrheic alopecia

Many people think that seborrheic alopecia has nothing to do with themselves, but in fact, the probability of suffering from seborrheic alopecia among urban people is very high. Seborrheic alopecia has become a very common and extremely harmful disease. So how is seborrheic alopecia caused? Only by understanding the root cause of your seborrheic alopecia can you truly find treatment and conditioning methods.

1. Mental or physical factors

Excessive mental stress is a common cause of hair loss. Mental stress, depression, fear or severe insomnia can all lead to nervous dysfunction, causing the capillaries to be continuously in a state of contraction and the hair follicles to lack adequate blood supply. The scalp is located at the top of the human body, so hair is most likely to fall out. If the stress continues and the psychological quality is weak, it is easy to develop hair cutting, hair eating, and hair pulling. Head trauma and lesions of the spinal cord, medulla oblongata, midbrain and brainstem can all cause hair loss. Mental factors can also seriously affect the hair growth cycle. Long-term visual fatigue, excessive mental stress, excessive nervous tension, irritability or anxiety, staying up late, etc. can all lead to a shortened hair growth cycle and hair loss.

2. Hormone imbalance and genetic factors

The growth hormone secreted by the pituitary gland can promote hair growth, while the lack of growth hormone will slow down the growth of hair. Sex hormones also affect the health of hair: female hormones make hair soft and shiny; male hormones make hair hard and thick. Once the sex hormones in the body lose balance, hair abnormalities may occur. Therefore, postpartum, menopausal, oral contraceptives, etc. will cause estrogen deficiency and hair loss within a certain period of time; hypopituitarism, adrenal tumors, late-stage acromegaly, etc. can all lead to hair loss. Most women will experience hair loss as they approach menopause. It has been proven that hair loss can indeed be caused by hormones. If this is the case, you can choose to receive hormone treatment or take medication prescribed by a doctor.

3. Factors that cause hair loss due to diseases

Anemia, malnutrition, acute high fever, infectious diseases or long-term liver disease, if they interfere with the function of the hair matrix cells at the hair root, it will affect the growth and color of the hair, and even inhibit the normal division of the hair matrix cells, causing the hair to enter a resting phase and cause hair loss. In addition, when suffering from ovarian tumors, excessive secretion of male hormones may cause increased dandruff and greasy hair, leading to seborrheic dermatitis and hair loss.

4. The relationship between drugs and hair

Many medications can damage hair and hinder its beauty. Immunosuppressants, chemotherapy drugs, arsenic agents and other drugs can cause hair loss. Long-term use of antibiotics and painkillers can easily cause hair to become thin and short and fall out. Some nutritional supplements contain stimulants, which can easily damage your hair if used for a long time. Common medications such as antidepressants and high blood pressure drugs can cause hair loss, and doctors may recommend that patients switch to other medications. Other drug treatment factors include chemotherapy, diet pills, stomach ulcer medicine, and vitamin A acid. As for chemotherapy for cancer treatment, many people know that it can cause hair loss. This is because chemotherapy kills any rapidly dividing cells other than cancer cells, including hair root cells in the growth phase, so about 90% of the hair will fall out. When chemotherapy stops, hair will gradually regrow.
