Nearly 80% of people in the United States say they spend more money on hair products than any other grooming Goods. But no matter what the bottle of expensive shampoo says about nourishing your hair, it can’t feed something that isn’t alive.
Despite all the effort we put into quaffing and pampering our locks, the hair we see is biologically dead. Hair is alive only in the roots, which are fed by small blood vessels beneath the skin’s surface. Hair cells travel up the shaft and are eventually cut off from the blood supply that is their nourishment. The cells die before being pushed out of the follicle on to the head or back, arm, or anywhere else.
Even though it’s dead, hair is incredibly strong. The average head of hair can support roughly 12 tons of weight. Much more than the scalp it’s attached to. The tough stuff grows in cycles. During the first phase, hair is actively growing. In the second phase, it rests in the follicle until it is pushed out of the root. Healthy hair grows a little less than 1/2 inch per month.
Each hair is completely independent from the others. When a hair falls out, another one may not grow directly in its place. The average person loses between 50 and 100 resting hairs each day. We are born with every hair follicle we will ever have, though the composition, color, and pattern of the hair changes over the years. A characteristic full head of hair average is about 120,000 to 150,000 individual hairs, about 250 hairs on each square centimeter of scalp.
Eating a healthful diet that contains sufficient protein (hair is made of protein), vitamins, minerals, and water is the best way to ensure healthy hair. A better investment is on nutrient dense foods rather than hair products.
Lathering, rinsing, and repeating will only wash a lot of money down the drain.
