A common belief is that dandruff is a dry scalp complaint. In fact, the opposite is true! Dandruff thrives with oily skin characteristics. Fungi spores are found naturally. Within the normal scalp secretions. Not everyone suffers from dandruff. But a lot of us do. From very mild to extremely obvious. If you suffer from dandruff it means your scalp is hyper-sensitive to these fungi spores.
So, pityriasis simplex or the little white flakes or sometimes powder are little collections of oil, wax and dead skin cells. They adhere to the hair shaft. Also, cling onto our clothes. Susceptibility to this condition is derived from our genetic makeup. That said, some outside influences can make the condition worse.
Is your dandruff related to your diet? It is suggested by some experts it maybe. Although there have been no conclusive reports. An unhealthy or improper digestive system is also a reason for dandruff worries. Include garlic, onions and scallions in your diet. They all contain allicin. Allicin is a healthy compound that is anti-bacterial and anti-fungal. It can help combat dandruff. A good idea is a food rich in probiotics (fermented food). These can include, kanji, idli, homemade pickles, dhokla, miso and home-made curd. Fish, flaxseeds and walnuts in your diet. Omega-3 fatty acids keep your scalp hydrated. Biotin (Vitamin B7) also helps combat dandruff. Foods such as salmon, sweet potatoes, egg yolks and almonds are a good source of biotin.
Note, not shampooing every day. Using the wrong type of shampoo and applying conditioners. Or, using greasy/oily hair products on your scalp will all exacerbate dandruff. Seek the advice of a professional, dermatologists can prepare a treatment personal to your condition.
