In order to get rid of dandruff, it is important to first understand its causes. The causes of dandruff are not yet 100% understood, but it is believed that “Malassezia” plays a key role in the formation of dandruff. In addition, some skin diseases can also cause dandruff, such as eczema, psoriasis and allergic contact dermatitis caused by hair dyes and shampoos, all of which may lead to increased dandruff. Therefore, it is first necessary to clarify whether it is true dandruff and eradicate the corresponding disease. In terms of pathogenesis, factors such as the parasitic growth of microorganisms such as Malassezia and changes in the chemical composition of the skin can affect the metabolism of local epidermal cells, so that the rate of epidermal cell turnover increases, but the keratinocytes that are shed are closely associated with each other and do not loosen normally, thus forming dandruff visible to the naked eye, which is dandruff. Therefore, the drug achieves the effect of treating dandruff by inhibiting the proliferation of epidermal cells, promoting the maturation and loosening of keratinocytes, and inhibiting the growth of fungi. If it is simple dandruff, only the dandruff increases and forms a piece of white dandruff, you can consider choosing shampoos with anti-dandruff function (such as Haifei Silk, Puffy, etc.), these shampoos often contain selenium sulfide, ZPT (zinc pyrithione), etc. The main function is to inhibit the growth of Malassezia, which can play a certain role in removing dandruff. If the number of dandruff is relatively high and the effect of anti-dandruff shampoo is not good, you can consider using Celebrex as well as some homemade shampoos made by the hospital to remove dandruff, which can relieve the dandruff problem more effectively. If the situation is more serious and has progressed to red, greasy scabs on the scalp with varying degrees of itchy discomfort, i.e., after becoming seborrheic dermatitis, it is best to seek help from a doctor at the hospital, and a combination of antifungal drugs and corticosteroid preparations will be considered. Since Malassezia is a normal flora parasitic on the surface of human skin, it is difficult for either shampoos or drugs to have the effect of completely removing Malassezia and eradicating dandruff. Therefore, once you stop using shampoo or medicine, dandruff is likely to “come back”. Therefore, in order to suppress dandruff, you should be prepared to fight a “long war”, that is, to adhere to the regular use of long-term anti-dandruff shampoo. In addition to the overgrowth and reproduction of Malassezia is the main cause of dandruff, psycho-neurological factors, life and diet also play an important role. It is necessary to start by changing living habits and adjusting the state of physical health and mental state. In fact, people can take dandruff as a pointer to the metabolic condition of the human body and the amount of stress it is under, and if the stress is not solved for a long time, it will easily lead to metabolic disorders, gastrointestinal dysfunction, cardiovascular and cerebrovascular diseases, depression and so on. Therefore, to solve the dandruff problem, but also try to stay up as little as possible, to maintain a regular life; adjust the mental state, try to relieve tension and anxiety; eat less spicy food, quit smoking and limit alcohol, a balanced diet; reasonable exercise, good hygiene habits. Some people think that the more black sesame and walnuts you eat the better for your hair, but in fact this is one-sided, for those individuals with overflowing scalp oil, these foods will make the scalp more greasy, but will aggravate dandruff. In fact, a balanced diet is more important to maintain good health.
