what is the cause of dandruff on scalp

In life, a few patches of dandruff on a neat and clean black blazer is an extremely degrading phenomenon. Dandruff also tends to cause itching and makes people restless. According to research, dandruff is mainly caused by a fungus called Malassezia furfur, which mainly relies on scalp oil to survive and will cause itchy scalp and produce a lot of dandruff when it overpopulates. The following eight causes of dandruff are currently recognized.

High oiliness of the scalp

An oily scalp can lead to dandruff because the fungus Malassezia furfur feeds on scalp oil, and an oily scalp can lead to a proliferation of this fungus, making it particularly prone to dandruff.

Anxiety

Anxiety can cause dandruff. The human body is an organic and complex whole, and in scientific research, there have been countless experiments proving that psychological changes in people cause physiological changes. Nervous and anxious emotions can lead to hormone secretion disorders in the human body and affect the health of the scalp. To relieve the mental state of anxiety and nervousness, you should learn to control your emotions, which can be achieved by contacting yoga, playing outdoor sports and participating in more social activities.

Sleep deprivation

Lack of sleep can lead to high dandruff. Adequate sleep can promote the normal metabolism of the skin. Nowadays, young people should try to avoid staying up late and preferably go to bed before 11:00 p.m. Adequate sleep can relieve dandruff symptoms.

Spicy diet

A spicy diet can cause dandruff. Spicy diet, smoking and alcohol will make the body take in harmful substances, which will affect the body's metabolism and the body's absorption of nutrients. Therefore, pay attention to diet and nutrition, eat protein-rich food often, and eat more fresh fruits and vegetables.

Physical discomfort

Physical discomfort can lead to high dandruff. We are also prone to increased dandruff when we are physically unwell, such as gastrointestinal dysfunction, nutritional imbalance and endocrine disorders, all of which can lead to changes in the body's hormone levels .

Shampoo allergy

Shampoo allergies can cause dandruff mostly because allergic reactions can change the scalp environment, allowing fungal overgrowth and breeding dandruff. In addition, there are many hair products that can also cause contact dermatitis of the scalp, such as hair dyes, hairsprays, and mousses.

Over-cleaning

Over-cleaning can lead to high dandruff. Some people believe that it is not hygienic enough when dandruff appears, so they increase the frequency of washing hair, which is a wrong understanding. Excessive shampooing can make the scalp dry and dehydrated, which in turn can aggravate dandruff. Dermatological skin diseases are often the cause of increased dandruff, and the common ones are seborrheic dermatitis of the scalp, scalp psoriasis and neurodermatitis, etc. Patients with these diseases should seek medical attention in a timely manner.
