Hair facts and functions

Curently in the USA approximately 50 million men and women are affected by thinning hair. Hair undergoes a cyclic process, which begins with a hair development stage called anagen, then followed by hair death or catagen and ends with follicle rest or telegen. A full cycle can take many years to complete and as hair goes through its cycle of growth, we grow and lose hair constantly. When hair is thinning, one may wonder if the hair loss is a normal cyclic thinning or if it is as a result of some abnormality. To find out we have to know the normal facts and function of the hair and hair follicles.

Normally we have about 100,000 to 150,000 strands of hair on the scalp, and the average life span of hair is about 2-7 years. It is normal to lose about 80-100 strands of hair each day and still not experience hair loss because of its cycle. Usually we lose more hair during the summer than we do during the winter time which could be for natural protection of the body against cold weather. Hair is the thickest around age 20 and it continues to become thinner by the age of 65-70. Hair loss is genetically predisposed and can be inherited from either or both parents. Hair follicles that are sensitive to DHT male hormone begin to shrink as men age and eventually will not grow. Hair loss in men averages 15% between ages of 18-29 and increases to approximately 50% by the age of 50. By age 40 the rate of hair loss decreases to 10% for each decade.

When experiencing hair loss, the most common cause is genetic, however other factors such as mechanical hair loss or systemic diseases could also be a factor. The breaking strength of hair is 160g, and it can be stretched as much as 30% when the hair is wet before breaking. The Average growth rate for hair is about 0.38 mm per day or 0.5 inches per month. Growth rate is increased during adolescence and slows down during older age, pregnancy, illness and cold weather. Living in cooler weather has been associated with blonder hair due to less melanin, while those in warmer temperatures are said to have darker and thicker hair. To determine if the hair loss is normal or as a result of other functions one need to see a doctor and do a hair test study to evaluate and predict future hair loss.
