Anti-dandruff shampoo can only be used a few times a week

There are many factors that cause dandruff. There are three conditions: oily skin, spicy food and mental stress. In addition, climate change, lack of sleep, excessive smoking and drinking, poor blood circulation, gastrointestinal indigestion, etc. can also cause dandruff.

When you shake your hair, the hair falls in the air. The trouble of dandruff makes people feel embarrassed and helpless. The emergence of anti-dandruff shampoo has given them good news. They use it almost every time they wash their hair, but is it really effective? The answer is no.

"There are many factors that cause dandruff." Chang Jianmin, chief physician of the dermatology department of Beijing Hospital, told our reporter that there are mainly three situations: oily skin, spicy diet and mental stress. In addition, climate change, lack of sleep, excessive smoking and drinking, poor blood circulation, gastrointestinal indigestion, etc. can also cause dandruff.

At present, the main ingredient of anti-dandruff shampoo on the market is ketoconazole, which can inhibit the reproduction of fungi to alleviate the condition of dandruff. Although the effect is immediate, if used frequently, fungal drugs will irritate the scalp, causing the dry and loose skin on the scalp to decompose and peel off, which will aggravate the symptoms of dandruff.

If you only have mild dandruff problems, you can completely solve it by adjusting your diet structure and eating less spicy, irritating foods and high-fat, high-calorie greasy foods.

You can buy two kinds of shampoo, one regular and one anti-dandruff. You only need to use anti-dandruff shampoo once a week, and use regular shampoo for the rest of the time. For people with severe dandruff, use anti-dandruff shampoo no more than three times a week. Because dandruff does not dissolve during the cleansing process, it cannot be removed by washing alone. Excessive washing will destroy the protective oil on the surface of the scalp. It is recommended that such people go to the hospital for treatment. After the doctor gives a reasonable diagnosis, they should choose the appropriate dandruff removal method based on the different causes of dandruff.
