Hair grows about an inch every couple of months. Each hair grows for 2 to 6 years, remains at that length for a short period, and then falls out. A new hair soon begins growing in its place. At any one time, about 85% of the hair on your head is in the growing phase and 15% is not. Each hair sits in a cavity in the skin called a follicle. Baldness in men occurs when the follicles shrink over time, resulting in shorter and finer hair. Miniaturization is part of the balding process when the thickness of one's hair shaft shrinks, or becomes thinner and thinner over time. When hair miniaturizes, it often is less long as the hair growth slows down. More advanced miniaturization will stunt the hair growth almost completely, a stage before it falls out.
Thickness and the general health of hair can be measured by examining it under a special microscope, called a densitometer, for signs of miniaturization. Increased miniaturization in certain patterns, reflect a progression of balding. In addition, miniaturization and detectable hair loss is not evident to the naked eye until more than 50% of normal (non-miniaturized)
Although there are a few causes for miniaturization, the most common causes are due to genetics, age, or androgens. If you are balding, you should have your scalp hair mapped for miniaturization to estimate the pattern of hair loss now and for future loss, and to measure the starting point for miniaturization so that changes measured over time, can be followed. These measurements are very fast and easy. It is almost nearly impossible to find miniaturized hairs on your own scalp. A dermatologist or hair restoration specialist would be better at spotting them as they are trained to do so and use hair magnification.
