Learn hair loss

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.

General debility, caused by severe or long standing illnesses like typhoid, syphilis, chronic cold, influenza and anaemia, also gives rise to hair disorders. It makes the roots of the hair weak, resulting in falling of hair. An unclean condition of the scalp can also cause loss of hair. This weakens the hair roots by blocking the pores with the collected dirt. Heredity is another predisposing factor which may cause hair to fall.

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.

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.

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.

Minoxidil (Rogaine). This over-the-counter medication is approved for the treatment of androgenetic alopecia and alopecia areata. Minoxidil is a liquid that you rub into your scalp twice daily to regrow hair and to prevent further loss. Some people experience some hair regrowth or a slower rate of hair loss or both. Minoxidil is available in a 2 percent solution and in a 5 percent solution.

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.

Finasteride is not approved for use by women. In fact, it poses significant danger to women of childbearing age. If you're a pregnant woman, don't even handle crushed or broken finasteride tablets because absorption of the drug may cause serious birth defects in male fetuses.




Conditions that can cause hair loss

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.

Alopecia Areata Childbirth - When a women is pregnant, more of her hairs will be growing. However, after a woman delivers her baby, many hairs enter the resting phase of the hair cycle. Within two to three months, some women will notice large amounts of hair coming out in their brushes and combs. This can last one to six months, but resolves completely in most cases.

Inadequate Protein in Diet - Some people who go on crash diets that are low in protein, or have severely abnormal eating habits, may develop protein malnutrition. The body will save protein by shifting growing hairs into the resting phase. Massive hair shedding can occur two to three months later. Hair can then be pulled out by the roots fairly easily. This condition can be reversed and prevented by eating the proper amount of protein and, when dieting, maintaining adequate protein intake.

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.

Major Surgery/Chronic Illness - Anyone who has a major operation may notice increased hair shedding within one to three months afterwards. The condition reverses itself within a few months but people who have a severe chronic illness may shed hair indefinitely.

Fungus Infection (Ringworm) of the Scalp - Caused by a fungus infection, ringworm (which has nothing to do with worms) begins with small patches of scaling that can spread and result in broken hair, redness, swelling, and even oozing. This contagious disease is most common in children and oral medication will cure it.




Steps to healthier hair

It is good to shampoo your hair--we recommend at least three times a week. This helps to remove dirt and buildup on the hair that can deteriorate the condition of your scalp. When shampooing, it is very important that you pay attention to cleansing your hair, your scalp and your hair line.

Many people (wrongly) will drop a handful of shampoo on their head and then rinse it off. Shampoo must be worked through all of your hair, as well as the scalp and hairline.

Nutritionists advise healthy hair seekers to eat well-balanced diets that incorporate healthy proteins along with foods high in vitamins B, C, E, A and K. Hair instantly responds to the addition of protein-rich foods such as meats, eggs, cheese, seeds and nuts. Fish packs a double punch of protein combined with health building essential fatty acids and natural oils. We recommend you discuss your diet with a medical professional.




Normal hair growth

There are two kinds, eumelanin which creates brown or black hair, and pheomelanin which makes hair appear red. Blonde hair is a result of very low amounts of melanin, the shade of the blonde again depends upon which type of melanin you have. Gray hair is a result of a lack of melanin which is often caused by age but can also be caused by stress and illness.

Hair that is dark and very visible is known as Terminal hair. Terminal hair is the hair that we refer to when talk about hair. Whether a hair is a fine vellus hair or a thick dark hair depends entirely on the follicle that is producing the hair. In balding men thick terminal hair is often replaced by fine vellus hair. This is a result of the hair producing equipment, the follicle, suffering physical damage and being unable to produce terminal hair.

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.
