The Production of Hair The hair follicle is the factory where the hair and the hair coloring are produced. As you can see from the drawing, it is a complex mechanism. The activity of each follicle in human beings is independent of the others (a mosaic pattern). Some animals shed their hair when warm weather comes: all the follicles go into the telogen or resting stage at one time. Human beings with healthy follicles, however, usually do not shed great amounts of hair. Since ninety percent of healthy hair follicles are in the growing stage at all times, no loss of hair is evident. The hair matrix at the base of the follicle is where the action takes place. The cells in this area produce keratin, the tough protein of which the hair is made, and melanin which stains the keratin giving the hair its color. This action takes place only during the growing stage of the hair cycle. You can also see in the drawing that the follicle is nourished by a network of capillaries. These capillaries are the delivery system bringing nutrients (amino acids, vitamins, minerals) to the base of the follicle. The amount of blood available to the scalp and therefore to the follicles is determined by the health of the capillaries in the scalp and the arteries in the neck and temples. Hair synthesis and melanin production are complex processes carried on deep in the follicle's core. Superficial cures for baldness like shampoos to "unclog" the follicles or tonics with "active ingredients" to stimulate hair growth just don't work. The Role of Heredity In order to interpret the biological role of heredity in hair loss it is necessary to differentiate between heredity and predisposition. Heredity is the genetic potential you are born with: eye color, skin color, hair color. These are the biological givens that are on your driver's license. On the other hand, predisposition is the tendency of the body to acquire certain disorders: obesity, diabetes, hair loss. These are the things you don't like about yourself when you have an examination or look in the mirror. Can you reverse predisposition? You can't eliminate the predispositions of the body but you can often contain them. For example, if you have the predisposition to obesity or diabetes, you can elect to change your life style. You can go on a low-calorie diet stressing fruits and vegetables. You can also exercise every day or at least keep active. The same is true about the predisposition to hair loss. Generic Proscar, Gneric Propecia, and Dutasteride (Avodart) will all counteract the predisposition to baldness. The approximately one hundred thousand hairs on the human scalp once they leave the hair canal are biologically dead. They can be dyed and curled and straightened, but they cannot be coaxed back to luxuriant teenage health by anything a barber or a beautician or a health food store can offer.
