As stated earlier, major factors for
healthy hair of any type remains both genetics and health. A well understood factor to optimum health is nutrition, and this element remains true for hair health. The living part of hair is under the scalp skin where the hair root is housed in the hair
follicle. The entire follicle and root are fed by a vein, and blood carries nutrients to the follicle/root. Any time an individual has any kind of health concern from stress, trauma, medications of various sorts, chronic medical conditions or medical conditions that come and then wane, heavy metals in waters and food, smoking...these and more can affect the hair, its
growth, and its appearance. If one wants to
improve their hair health, one thing to improve is what one eats. Generally, eating a full diet that contains protein, fruits, vegetables, grains, and even an appropriate amount of fat is important (several vitamins and minerals require fat in order to be delivered or absorbed by the body). Any deficiency will typically show first in the hair, perhaps even before it is diagnosed. For example, even a mild case of anemia can cause shedding and hair loss. When the body is under strain, it reprioritizes its processes. For example, the vital organs will be attended to first, meaning that healthy, oxygenated blood may not feed into the hair follicle, resulting in less healthy hair or a decline in growth rate. While not all hair growth issues stem from malnutrition, it is a valuable symptom in diagnosis
