Hair loss types

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.

Another important cause of falling hair is stress, such as worry, anxiety and sudden shock. Stress leads to a severe tension in the skin of the scalp. This adversely affects the supply of essential nutrition required for the healthy growth of hair.

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.

Silicon bags are inserted beneath an area of hairy scalp and gradually inflated with saline water over a six-week period. This causes the hair-bearing skin to stretch, thus increasing the amount of hair-bearing scalp. After removing the bags, expanded hair bearing skin is lifted and moved to an adjacent bald area where a similar sized patch of scalp has been excised.

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.

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 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.

Anthralin (Drithocreme). Available as either a cream or an ointment, anthralin is a synthetic, tarry substance that you apply to your scalp and wash off daily. It's typically used to treat psoriasis, but doctors can prescribe it to treat other skin conditions. Anthralin may stimulate new hair growth for cases of alopecia areata.

Hair growth

The outer layer is called the cuticle and is thin and colorless, its job is to protect the thicker cortex which contains the melanin. Melanin is responsible for the color of your hair and the actual color depends on what kind of melanin you have .

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.

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.

Causes of excessive hair loss

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.

Thyroid Disease - Both an over-active thyroid and an under-active thyroid can cause hair loss. Your physician can diagnosis thyroid disease with laboratory tests. Hair loss associated with thyroid disease can be reversed with proper treatment.

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.

Cancer Treatments - Some cancer treatments will cause hair cells to stop dividing. Hairs become thin and break off as they exit the scalp. This occurs one to three weeks after the treatment. Patients can lose up to 90 percent of their scalp hair. The hair will regrow after treatment ends. Patients may want to get wigs before treatment.

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.

Hair Pulling (Trichotillomania) - Children and sometimes adults will twist or pull their hair, brows or lashes until they come out. In children especially, this is often just a bad habit that gets better when the harmful effects of that habit are explained. Sometimes hair pulling can be a coping response to unpleasant stresses and occasionally is a sign of a serious problem needing the help of a mental health professional.

Hair care tips

Correct use of conditioners containing light proteins, such as hydrolyzed human hair keratin proteins, can help strengthen your hair. A good conditioner with these proteins can easily penetrate the hair shaft to replenish nutrients. These proteins can also repair split ends. Split ends develop after the protective cuticle has been stripped away from the end of hair fibers as a result of harsh chemicals or even vigorous brushing.

Excessive exposure to the sun can damage your hair by inducing oxidation of the sulfur molecules within the hair shaft, leaving the hair weak, brittle, dry and faded. People who bleach or lighten their natural hair color may also notice slight color changes in their hair when it is exposed to sun.

Hair requires the same overall nutrition that the body does: plenty of fresh fruits and vegetables, grains and protein including lean meat and fish. Dietitians recommend foods high in biotin, including brown rice, bulgar, brewer's yeast, soybeans, green peas, lentils, oats, sunflower, seeds and nutritious nuts.

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.

Women hair loss

Hair transplantation has come a long way from the days of "hair plugs" and a pleasing, natural result is now routine. It is an excellent option for treatment of hereditary hair loss in many men and women.

The site from where the hair is taken is usually a fine scar line which is hidden by the permanent hair in that area. After the procedure there are tiny marks where the grafts have been placed. Initially there is some crusting over these areas (5-14 days) but after this, these areas are usually not detectable.

In most cases, immediately after the hair transplant the hairs fall out of the grafts, and do not regrow for 1-3 months. After this they begin to grow as normal hair. With each session there is more hair, and the resulting appearance is thicker hair.

Women with localized thinning on the top of their heads or thinning around the temples often make good candidates for hair transplantation. Prior to evaluation for hair transplantation, it is important for women to discuss your thinning hair with a dermatologist and/or endocrinologist to make sure there is no other treatable reason for the hair loss.

Hair transplantation can be done both on patients with advanced baldness and earlier thinning. Newer treatments for men like Propecia or for both men and women, like Rogaine should be considered as well especially in patients with earlier thinning as these medications often slow significantly the progression of hair loss. In general, hair transplantation is not considered for patients younger than their mid 20s because of difficulty in predicting ultimate extent of hair loss.

Many women today are proactive about seeking hair transplantation. They are unwilling to accept hair loss as an unavoidable fact of life. Scalp hair is a major component of the image women project to the world and they do not wish to have hair loss detract from that image.

A woman who has a family history of hair loss in women may be especially aware of the possibility that she may also begin to lose hair as she matures. And, she would be correct; a family history of hair loss in women is an indication that a woman may be genetically predisposed to lose hair.
