Why is hair loss so serious?

Serious alopecia may be caused by heredity, perming, dyeing hair, using irritating shampoo and other physiological reasons, or by malnutrition, infection, mental factors, drug factors, endocrine factors, skin diseases and other pathological factors. It is suggested that specialists should make a comprehensive judgment according to the examination results and the patient's personal situation.

First, physiological reasons:

1, Hereditary: If the patient has hereditary androgenetic alopecia, it will cause the hair follicle to be too sensitive to androgen, and then the hair follicle will gradually shrink and form alopecia, and individual cases will be more serious;

2. Perm, dye hair and use irritating shampoo: If the patient excessively perms and dyes hair for a long time, or uses some shampoos containing irritating substances, it will also damage and irritate the scalp, leading to serious hair loss.

Second, the pathological reasons:

1, malnutrition: if the patient is in the stage of excessive dieting and weight loss, due to insufficient nutrition intake, the hair lacks nutrition supply, which can lead to serious hair loss;

2, infection: fungi, bacteria and other infections can cause hair follicle damage and scar formation, and eventually form permanent hair loss, which is generally more serious at this time;

3. Mental factors: If the patient has long-term mental stress or sudden stress, it will lead to endocrine disorders, and it can also lead to severe hair loss such as alopecia areata;

4. Drug factors: Some chemotherapy drugs for malignant tumors can cause severe alopecia, such as cyclophosphamide and paclitaxel, but the symptoms of alopecia can be improved after stopping the drug;

5. Endocrine factors: Hair growth is closely related to endocrine hormones. If the patient suffers from endocrine diseases such as hypothyroidism or hyperthyroidism, it will lead to endocrine abnormalities and severe hair loss;

6. Dermatosis: When patients suffer from lupus erythematosus, lichen planus and other diseases, scalp injury may occur, which in turn causes cicatricial alopecia, and the degree of alopecia is more serious.

In addition, postpartum hormone level instability, scalp trauma, vitiligo, Hashimoto's thyroiditis and other autoimmune diseases can also lead to serious hair loss. It is suggested that patients go to a specialized hospital for physical examination as soon as possible to avoid delaying treatment.
