The manifestation of excessive and itchy dandruff should be treated in a comprehensive and systematic manner according to the cause, and it must be ruled out whether the patient has folliculitis, seborrhea or scalp eczema. If there is head inflammation, it is possible to stimulate the metabolism of the scalp to increase, which in turn will stimulate the nerves around the scalp and make the dandruff itchy. Therefore, it is necessary to strengthen the clean care of the scalp and keep it clean and dry. At the same time, for certain inflammatory diseases, local anti-bacterial creams can be applied for treatment. In addition, for increased dandruff, you can also usually supplement fresh vegetables and fruits, while avoiding excessive mental tension, ensuring regular rest and not staying up late.
