The healthy condition of the hair depends, to a very large extent, on the intake of sufficient amounts of essential nutrients in the daily diet. Hair is made of keratin, a protein, which also makes up the nails and the outer layer of our skin. One of the primary cause of hair loss is a high amount of the male hormone, dihydrotestosterone (DHT) within the hair follicle. DHT is produced from testosterone in the prostate, various adrenal glands, and the scalp. After a period of time, an over abundance of DHT causes the hair follicle to degrade and shortens the active phase of the hair. Another factor that has been linked to hair loss is the amount of sebum in the scalp. Sebum contains a high amount of DHT, and clogs pores in the scalp, both of which cause the malnutrition of the hair root. The amount of sebum in balding hair is related to the amount of oil in the hair. Meanwhile most doctors agree that frequent shampooing is advised in hair loss cases with oily scalps. The most important cause of hair loss is inadequate nutrition. Even a partial lack of almost any nutrient may cause hair to fall. But hair grows normally after a liberal intake of these vitamins. A high protein and and an iron rich diet is recommended for hair loss. An adequate intake of raw vegetables, fresh fruits, salads, green leafy vegetables should be included in the diet on a regular basis. Women require 60 grams, men 80 to 90 grams, adolescent boys and girls 80 to 100 grams of protein. It is supplied by milk, buttermilk, yogurt, soyabean, eggs, cheese, meat and fish. A deficiency of some of the B vitamins, of iron, copper and iodine may cause hair disorders like falling of hair and premature greying of hair. Scalp reduction is performed on patients with well-defined bald spots in the crown area of the scalp. It is sometimes done in conjunction with hair transplantaion to reduce the size of the bald scalp, especially in patients who do not have enough donor hair to cover the bald areas. 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. The effectiveness of medications used to treat alopecia depends on the cause of hair loss, extent of the loss and individual response. Generally, treatment is less effective for more extensive cases of hair loss. Finasteride (Propecia). This prescription medication to treat male-pattern baldness is taken daily in pill form. Many people taking finasteride experience a slowing of hair loss, and some may show some new hair growth. Positive results may take several months. Finasteride works by inhibiting the conversion of testosterone into dihydrotestosterone (DHT), a hormone that shrinks hair follicles and is an important factor in male hair loss. Rare side effects of finasteride include diminished sex drive and sexual function. As with minoxidil, the benefits of finasteride stop if you stop using it.
Hair loss and thinning hair can be brought on by a variety of different conditions. Although, many researchers still pin most of the blame on genetics. The most common type of hair loss is referred to as "pattern hair loss" (androgenic alopecia). Many natural hair loss treatments exist that can help deal with pattern hair loss. Listed below are other conditions which can cause hair loss and thinning hair. Do you feel that you are the only one losing hair? You're not! The most common form of hair loss, Androgentic Alopecia, or pattern baldness, is experiences by 50-80% of Caucasian men. The number of Chinese males affected are half of the Caucasian counterparts while African Americans have a lower incidence of the condition as well. For women androgenetic alopecia occurs between 20-40% of the general female population. In summary, it is safe to say that pattern baldness is experienced by the norm of the population, you're not alone, but actually in the majority. Alopecia Areata - In this type of hair loss, hair usually falls out, resulting in totally smooth, round patches about the size of a coin or larger. It can, rarely, result in complete loss of scalp and body hair. This disease may affect children or adults of any age. The cause of alopecia areata is unknown. Apart from the hair loss, affected persons are generally in excellent health. In most cases, the hair regrows by itself. Dermatologists can treat many people with this condition. Treatments include topical medications, a special kind of light treatment, or in some cases pills. Medications - Some prescription drugs may cause temporary hair shedding. Examples include some of the medicines used for the following: gout, arthritis, depression, heart problems, high blood pressure, or blood thinner. High doses of vitamin A may also cause hair shedding. Birth Control Pills - Women who lose hair while taking birth control pills usually have an inherited tendency for hair thinning. If hair thinning occurs, a woman can consult her gynecologist about switching to another birth control pill. When a women stops using oral contraceptives, she may notice that her hair begins shedding two or three months later. This may continue for six months when it usually stops. This is similar to hair loss after the birth of a child. See products which may help hair loss.
Hair is composed of Keratin, a special protein that also produces our fingernails and toenails the nails and forms the protective outer layer of our skin. Each strand of hair consists of three concentric layers, the cuticle, the cortex and the medulla. The physical thickness and length of hair depends on what type of hair it is. Vellus hair is the fine fuzz type of hair that's often called peach fuzz. Its very fine and colorless and often almost invisible to the naked eye. The average Caucasian person has 5 million hairs of which 100,000 - 150,000 are on the head. Blondes not only have more fun, they also have more hair, about 140,000 more than average, Brunettes have slightly higher than average hair about 105,000 hairs, and redheads have a little less than average about 90,000 hairs. About 90 percent of the hair on a person's scalp is growing at any one time. The growth phase lasts between two and six years. Ten percent of the hair is in a resting phase that lasts two to three months. At the end of its resting stage, the hair is shed. When a hair is shed, a new hair from the same follicle replaces it and the grow-ing cycle starts again.
