Types of hair loss

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.

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.

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.

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.

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.

Patterns of 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.

Androgenic alopecia develops when the hair follicle (the place under the skin where hair grows from) experiences a reduction in size, as well as a time reduction in the active growth phase. this translates into a simple fact: more and more of the hair follicles will spend time in the resting state where hair is shed once the state is completed. Fortunately, androgenic alopecia does not develop in all hair follicles at the same time. This is why some part of the scalp seems to be losing more hair than the other.

High Fever, Severe Infection, Severe Flu - Illnesses may cause hairs to enter the resting phase. Four weeks to three months after a high fever, severe illness or infection, a person may be shocked to see a lot of hair falling out. This shedding usually corrects itself.

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.

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 transplantation

Hair transplantation refers to the surgical movement of permanent hair with its roots to an area of bald or balding skin. Hair transplantation is an effective and permanent solution for hair loss.

In the hands of well-trained and experienced physicians, and using newer techniques with smaller grafts, the hair grows in the proper direction with a feathered hairline, and a highly aesthetic result.

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.

Hair transplantation is a cost-competitive solution for hair loss. Other hair replacement alternatives require additional maintenance over the years. The cost depends on the amount of bald area that will need to be transplanted, and the desired thickness. More grafts are necessary to cover more bald or thin area and to maximize hair density. Because the procedure is individual, costs are usually determined individually.

Hair transplantation is universally accepted as a treatment for hair loss. While it was developed and first offered as a hair-loss treatment for men, women have increasingly found hair transplantation a viable option to correct the cosmetic deficit of thinning hair. Advances in hair transplantation techniques and better understanding of the biology of female hair loss contributed to the evolution of hair transplantation got women.

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.

Almost worse than hair loss in some cases is hair miniaturization-the fine-caliber, wispy hair that grows out a follicle when the follicle is no longer able to produce hair of normal size. Miniaturized hair is hard to style and difficult to conceal. It begins to appear in the course of female pattern hair loss, the female form of the most common type of hair loss in men.

Whether hair transplantation is a viable option for a woman with mild to moderate hair loss is a question to be answered by close consultation between the woman and the physician hair restoration specialist. Into that determination will go the patient's medical history, hair loss history, family medical and hair loss history, physical examination, scalp examination and laboratory tests as indicated by other examination results.

How does hair grow?

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.

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 innermost layer of hair is called the medulla and reflects light giving hair the various color tones it has. That's why hair color looks a lot different in sunlight than it does in the shade.

Whether you have straight or curly hair depends on the shape of the cortex. If the cross section of the cortex is round you will have straight hair, if the cortex is oval shaped you will have curly or wavy hair.

Steps to healthier hair

Did you notice that when you shampoo your hair the amount of lather often varies? Usually, the more lather you have, the less buildup you have on your hair. It's also important to fully rinse out the shampoo to eliminate any residual detergents--they can damage the hair shaft and scalp.

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.
