The skin/ scalp should be slightly acidic, a perfect barrier against bacteria and to help eliminate any toxins from within our bodies. When the scalp becomes more alkaline this changes the pH content and a yeast can flourish in the nutrients available often producing scaly and itchy patches (dandruff). Diets that are high in Calcium (dairy) can promote an alkaline environment so should be reduced because as skin cells mature they move from the deeper layers to the outer surface, the excess Calcium slows this process down and this inhibits the normal moisture content. There is usually an increased need for certain minerals such as zinc and essential fatty acids too, and the use of a medicated shampoo. Most dry scalps will respond quickly but If symptoms become persistent examination may be necessary to rule out any underlying condition that may go on to cause hair loss.
