Hair loss and other disorders of scalp have certain underlying causes. Capillary vessels supply necessary nutrients and other substances to hair follicles through bloodstream. Our blood is a viable fluid that moves continuously. This fluid is composed of two principal components. These are plasma and blood cells. Today, there are many factors, unfortunately, that hinder supply of nutrients to hair follicles. Pioneering personal factors are genetics, circulatory disorders and aging, while environmental factors include smoking, unhealthy eating and cosmetic products.

An average human has 5 to 6 liters of blood in body. Plasma accounts for 50-60% of blood. Remaining 40 to 50 percent is formed by blood cells. Basically, blood contains three types of cells; erythrocytes (red blood cells), leukocytes (white blood cells) and platelets (cells responsible for coagulation). Platelets are smallest nucleus-free cells of blood. Their principal duty is to form blood clots; in other words, platelets found in blood discharging through a laceration generates a protective layer that stops bleeding. This layer also plays an important role in wound healing.
