Hair is in fact dead after it grows out of the hair follicle. The hair follicle stems from a bulb underneath your scalp. This bulb is fed with blood and is very sensitive. If this bulb is disturbed with shock, anxiety, age it dies and this is what turns hair gray as well as. The best remedy for this is to thouroughly massage your scalp as often as possible with a very good strong tea tree or mint oil. This keeps the blood flow to the bulbs stimulated and will keep the scalp healthy as well. Mental or physical stress is a major thinner of hair.

FOR MEN, hair loss is male pattern baldness. Yes, there are other types of hair loss, including rare conditions such as alopecia totalis and alopecia universalis, where the entire scalp and entire body, respectively, become completely bald due to a viral condition that is irreversible. There is also patch baldness, in which hair falls out in patches of the scalp. This is caused by stress or poor nutrition or adverse scalp conditions. But the hair will usually grow back once the cause has been rectified.
However, it is male pattern baldness that is the condition responsible for over 98% of all hair loss in men. It gets its name from the pattern of hair loss, which ultimately results in a horseshoe of hair that resides on the sides and back of the head, while the top of the head is completely bald. Some men begin MPB by losing the hair in their hairline. Others start in the crown. The most familiar hair loss pattern is where the hair begins to recede in the hairline and the crown at roughly the same time. The hair in the mid-scalp or anterior scalp is often the last to go. But go it will, eventually leaving a man with the horseshoe of hair that is the telltale sign of typical male pattern baldness.
FOR WOMEN, hair loss is different. There is no set pattern for womens androgenic hair loss, which like MPB, occurs in the overwhelming majority of cases. Women can suffer from alopecia totalis and alopecia universalis just like men. Women can experience patch baldness for the same reasons as men (stress, poor nutrition, etc.), as well as due to hormonal changes from pregnancy and certain eating disorders. However, like men, the hair will generally grow back. The chief difference in womens androgenic hair loss from mens (both are hormone related) is that women tend to experience thinning that occurs in no particular pattern or part of the scalp. Unlike men, the scalp may not actually be totally denuded of hair, just thin to the point where the scalp is visible. Like men, however, the resulting hair loss is generally irreversible
FOR BOTH MEN AND WOMEN, the cause of androgenic hair loss is, as its name implies, hormone related. It stems from a genetic predisposition for a by-product of the male hormone testosterone (yes, women have testosterone in their bodies, too), called DiHydroTestosterone (DHT) to reside in the scalp. All hair follicles grow through a growth-dormant-regrowth cycle. When DHT is present in the scalp at high levels, the hair follicles tend to increase their time of dormancy and decrease the time for growth. In actuality, the follicle atrophies due to the excess DHT. Each follicle produces hair for shorter periods and “rests” for longer periods, until it finally goes into permanent dormancy and ceases to produce hair. An interesting phenomenon is that in men, the DHT only seems to affect the hair follicles on top of the scalp. While DHT is present in the entire scalp, the hair follicles that reside on the sides and back of the head resist its deleterious effects. When hair from the sides and back of the head are transplanted to the top of a bald scalp, the same DHT that caused the original hair follicles to atrophy now has no effect on the transplanted follicles.

How is hair loss treated?
TOPICAL/LASER There are two medically approved drugs to combat hair loss and perhaps even grow hair. They are Rogaine* and Propecia*. Both originated as high blood pressure medications and both have reported limited success in the cessation of hair loss and even less success in the regrowing of new hair.
There are also non-medical topical solutions that purport to grow hair. Though the FDA does not recognize the hair cessation/hair growing properties of these lotions, there is anecdotal evidence to support their efficacy. So too with laser treatments. Lasers have been used to successfully treat many dermatological conditions and they have advocates who claim them to be effective in stopping hair loss and in some cases, growing new hair. Again, the evidence to support these claims is more anecdotal than clinical.
SURGICAL RESTORATION This refers mainly to transplants, but also to other surgical techniques. The purpose of surgical restoration is not to create new hair, but to move the good hair follicles into places where the bad hair follicles have failed. The physician literally makes a tiny incision into the donor area (in the back of the head) and removes follicles, inserting them into the top of the scalp, again with a tiny incision. Modern mini-grafting and micro-grafting techniques have resulted in convincing, natural looking hair transplants. The key to the success of the procedure lies largely in the donor hair; its quantity, quality, etc.
NON-SURGICAL RESTORATION This refers to any method in which the hair that is restored to the balding areas is not growing hair. Falling under this wide category are everything from toupees, weaves and hair systems to more sophisticated technology that grafts hair to the scalp through non-surgical means.
