Baldness science
What Is alopecia areata' male or female pattern baldness is considered an autoimmune disease, in which the immune system, which is designed to protect the body from foreign invaders such as viruses and bacteria, mistakenly attacks the hair follicles, the tiny cup-shaped stopped from which hairs grow, baldness science. This can lead to loss of hair on the scalp and other sites on the body. In most situations, hair falls out in small, round patches about the size of a quarter. In many cases, the affliction does not extend beyond a few bare patches. In some citizens, alopecia is more extensive. Although uncommon, baldness science, the ailment can go on to to cause total loss of hair on the head (referred to as alopecia totalis) or complete loss of hair on the head, face, and body (alopecia universalis). What Causes It' In pattern baldness, immune system cells called white blood cells assault the rapidly growing cells in the hair follicles that make the hair.
The problem hair follicles become tiny and drastically slow hair production. Fortunately, the stem cells that continually supply the follicle with new cells do not seem to be targeted. And so the follicle always has the potential to regrow hair - baldness science. Researchers do not know exactly why the hair follicles undergo these changes, baldness science but they suspect that a combination of genes may predispose some people to the disease. In those who are genetically predisposed, some type of trigger - perhaps a virus or something in the person's environment - brings on the attack against the hair follicles. Who Is Most Likely To Get It' alopecia areata affects an estimated 4 million Americans of both sexes and of all ages and ethnic backgrounds. It often starts in childhood baldness science. If you have a close family member with the condition, your risk of developing it is slightly increased. If your relative lost their first patch of hair before age 30, the risk to other relations is greater. On the whole, one in five individuals that are afflicted with the disease have a family member who has it also. Is My pattern baldness a Symptom of a Serious Disease' male or female pattern baldness is not a life-threatening affliction and neither is baldness science. It does not instigates any physical pain, and folks that have the affliction are generally healthy otherwise. But for most people, a condition that unpredictably seriously affects their appearance the way male or female pattern baldness does is a serious matter. The effects of alopecia areata are primarily socially and pschologically worrying. In alopecia universalis, however, loss of eyelashes and eyebrows and hair in the nose and ears can make the person more susceptible to dust, germs, and foreign particles entering the ears, nose, and eyes. pattern baldness often occurs in persons whose relations have other autoimmune ailments, such as Addison's disease, diabetes, rheumatoid arthritis, systemic lupus erythematosus, thyroid disease or pernicious anemia or even baldness science. People who have male or female pattern baldness do not commonly have other autoimmune conditions, but they do have a higher occurrence of atopic eczema, nasal allergies, asthma and thyroid disease, baldness science. Can I Pass It on to My Children' It is possible, but not likely, for alopecia areata to be inherited. Most children with pattern baldness do not have a parent with the affliction, and the vast majority of parents with alopecia areata do not pass it along to their children. male or female pattern baldness is not like some genetic diseases in which a child has a 50 50 chance of developing the condition if one parent has it. Hair research scientists believe that there may be a number of genes that predispose certain persons to the ailment. It is highly unlikely that a child would inherit all of the genes necessary to predispose him or her to the condition. Even with the right (or wrong) combination of genes, pattern baldness is not a certainty. In identical twins, who share all of the same genes, the concordance rate is only 55 percent. In other words, if one twin has the ailment, there is only a fifty five percent chance that the other twin will have it as well. This shows that other factors besides genetics are required to trigger the affliction. To learn more in respect of the genes and other considerations involved in pattern baldness risk, the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) is funding an alopecia areata registry baldness science. The registry is an organized network of five centers throughout the US that will identify and register patients with the disease and collect data and blood samples (which contain genes). Data, including genetic information, will be made available to scientists studying the genetic origin and other effects of disease and disease risk. (For more information with reference to the registry, see "How Can I Take Part In Research'") Will My Hair Ever Grow Back' The chances that your hair will regrow are extremely good, but it could also fall out again. It is not possible to predict whether it could regrow or fall out. The course of the condition varies from person to person. Some citizens lose just a few patches of hair, baldness science after which the hair grows back and the condition never recurs. Other individuals continue to lose and regrow hair for many years. A few people lose all the hair on their head; others lose all the hair on their head, face and body. Even for those individuals suffer from total hair loss, the possibility for full regrowth remains. In some, the initial hair re-growth is white, with a gradual return of the original hair color. In most, the regrown hair is finally the same color and texture as the original hair. What Can I Expect Next' The course of male or female pattern baldness is highly unpredictable, and the uncertainty of what will happen next is probably the most difficult and frustrating symptom of the affliction. You may continue to lose hair, or your hair loss may stop, baldness science. Your lost hair could grow back but it may not and it is possible that you may not continue to develop new bare patches. How Is It Treated' [While there is neither a cure for male or female pattern baldness nor drugs approved for its treatment], some people find that drugs approved for other purposes like male or female pattern baldness can help hair grow back, baldness science at least temporarily. The following are some treatments for alopecia areata. Keep in mind that while these methods of treatment may promote hair growth, none of them prevent new patches or actually cure the underlying disease. Consult your health care professional with reference to the best option for you. Corticosteroids - Corticosteroids are powerful anti-inflammatory drugs, baldness science, similar to a hormone known as cortisol produced in the body. Because these drugs suppress the immune system if given orally, they are often used in the treatment of several autoimmune diseases, including baldness science. Corticosteroids may be administered in 3 ways for pattern baldness:
Local innoculations - Injections of steroids directly into hairless patches on the scalp and sometimes the brow and beard areas are effective in hair growth in most folks. It usually takes about 4 weeks for new hair growth to become visible. Injections deliver tiny amounts of cortisone to affected areas, avoiding the more serious side effects encountered with long-term oral use. The main side effects of injections are transient pain, mild swelling, and occasionally changes in pigmentation, as well as small indentations in the skin that go away when innoculations are stopped. Because injections can be painful, they may not be the preferred treatment for children. After 4 to 8 weeks, new hair growth habitually becomes visible, and the injections ordinarily have to be repeated monthly. The cortisone takes out the confused immune cells and allows the hair to grow. Large areas cannot be treated, however, because the discomfort and the volume of medicine become too great and can result in side effects similar to those of the oral regimen. Oral corticosteroids - Corticosteroids taken orally are a mainstay of treatment for many autoimmune diseases and may be used in more extensive male or female pattern baldness. But because of the risk of side effects of oral corticosteroids, such as hypertension, baldness science and cataracts, they are used only occasionally for alopecia areata and for shorter periods of time. Topical ointments - ointments or creams containing steroids rubbed directly onto the problem area are less traumatic than innoculations and, therefore, are sometimes preferred for children. However, corticosteroid ointments and creams alone are less effective than injections; they work best when combined with other topical methods of treatment, such as minoxidil or anthralin.
Minoxidil (5%) (Rogaine) - Topical minoxidil mixture promotes hair growth in several conditions in which the hair follicle is tiny and not growing to its full potential. Minoxidil is FDA-approved for treating male and female pattern baldness. It may also be useful in promoting hair growth in pattern baldness. The tincture, applied twice daily, has been shown to promote hair growth in both adults and children, and may be used on the scalp, brow, and beard areas. With constant and proper use of the solution, new hair growth appears in with reference to three months. Brand names included in this article are provided as examples only, and their inclusion does not mean that these products are endorsed by the National Institutes of Health or any other Government agency. Also, if a particular brand name is not mentioned, this does not mean or imply that the product is not worthwhile. Anthralin (Psoriatec) - Anthralin, a synthetic tar-like substance that alters immune function in the affected skin, is an approved treatment for psoriasis. Anthralin is also commonly used to treat pattern baldness. Anthralin is applied for tenty to sixty minutes ("short contact therapy") to avoid skin irritation, baldness science which is not appropriate for the drug to work. When it works, new hair growth is typically evident in two to three months. Anthralin is often used in combination with other treatments, such as corticosteroid innoculations or minoxidil, for improved results. Sulfasalazine - A sulfa drug, sulfasalazine has been used as a treatment for different autoimmune disorders, including psoriasis. It acts on the immune system and has been used to some effect in patients with severe alopecia areata. Topical sensitizers - Topical sensitizers are medicines that, when applied to the scalp, provoke an allergic reaction that leads to itching, scaling, and eventually hair growth. If the medication works, new hair growth is normally established in 3 to 12 months. Two topical sensitizers are used in male or female pattern baldness: squaric acid dibutyl ester (SADBE) and diphenylcyclopropenone (DPCP). Their safety and consistency of formula are currently under review. Oral cyclosporine - Originally developed to keep persons's immune systems from rejecting transplanted organs, oral cyclosporine is occasionally used to suppress the immune system response in psoriasis and other immune-mediated skin conditions. But suppressing the immune system can also instigates problems, including an increased risk of serious infection and possibly skin cancer. Although oral cyclosporine may regrow hair in male or female pattern baldness, it does not turn the ailment off. Most physicians feel the dangers of the drug outweigh its benefits for alopecia areata and baldness science. Photochemotherapy - In photochemotherapy, a treatment used most commonly for psoriasis, a person is given a light-sensitive drug called a psoralen either orally or topically given and then exposed to an ultraviolet light source. This combined treatment is known as PUVA. In clinical trials, in the order of fifty five percent of people achieve cosmetically acceptable hair growth using photochemotherapy. However, the relapse rate is high, and patients must go to a treatment center where the equipment is available at least two or three times per week. Furthermore, the treatment sustains the risk of developing skin cancer. Alternative therapies - When drug methods of treatment fail to bring acceptable hair regrowth, some folks turn to other types of therapies - baldness science. Alternatives purported to help pattern baldness include zinc and vitamin supplements, evening primrose oil, acupuncture, aroma therapy, and Chinese herbs. Because many alternative therapies are not backed by clinical trials, they may or may not be effective for regrowing hair. In fact, some may in fact make loss of hair worse. Furthermore, just because these are natural therapies does not mean that they are safe to employ. As with any therapy, it is best to discuss these treatments with your doctor before you give them a try.
In addition to methods of treatment to help hair grow, there are measures that can be taken to minimize the physical dangers or downsides of losing your hair. Sunscreens are important for the scalp, face, and all areas of the body that are exposed. Spectacles (or sunglasses) protect the eyes from too much sunlight, and from dust and debris, when eyebrows or eyelashes are missing. Hairpieces, caps, or scarves protect the scalp from sun rays and keep the head warm. Antibiotic ointment applied inside the nostrils helps to protect against organisms invading the nose when nostril hair is missing.
How Will male or female pattern baldness Affect My Life and Lifestyle' This is a common question, particularly for children, teens and young adults who are starting to form lifelong goals and who may live with the effects of alopecia areata for many years, baldness science. It is a comfort to know pattern baldness is not a painful disease and does not make citizens feel sick physically. It is not contagious, and individuals who have the alopecia areata ailment are generally in good health otherwise. It does not reduce life expectancy and it should not interfere with the ability to achieve such life goals as going to school, working, marrying, raising a family, playing sports, and exercising. The emotional aspects of living with hair loss, however, can be a challenge. Many people cope by learning as much as they can about the condition; speaking with others who are facing the same problems; and, if necessary, looking for counseling to help construct a positive self-image. To address quality-of-life issues for baldness science, pattern baldness and all other skin afflictions, the NIAMS sponsored a scientific meeting in September 2002 on the burden of skin afflictions. How Can I Deal With With the Effects of This Disease' Living with baldness can be hard, especially in a culture that views a healthy head of hair as a sign of youthfulness and good health. Even so, most citizens with pattern baldness are well-adjusted, happy persons living full lives. The key to coping is valuing yourself for who you are, not for the amount of hair you have. Many individuals learning to deal with alopecia areata find it helpful to talk with other folks who are dealing with the same problems. More than 4 million citizens nationwide have this ailment at some point in their lives, so you are not in isolation. If you would like to be in touch with others with the condition, the National male or female pattern baldness Foundation (NAAF) can assist through its pen pal program, message boards, annual conference, and support groups that meet in various locations nationally. An alternative way to cope with the affliction is to lessen its effects on your appearance. If you are unfortunate enough to have total alopecia, a wig or hairpiece can look natural and contemporary. For small patches of baldness, a hair-colored crayon, cream or powder applied to the scalp can make alopecia less obvious by eliminating the contrast between the hair and the scalp. Skilfully applied baldness science eyebrow pencil can mask missing eyebrows. Children with alopecia areata may prefer to wear bandanas, scarves or caps. There are many styles available to suit a child's interest and mood - some even have ponytails fixed with baldness science. For women, attractive scarves can hide patchy hair loss; jewelry and clothing can distract attention from patchy hair; and proper makeup can cover up the effects of lost facial hair. If you would like to learn more about covering up the cosmetic effects of baldness science alopecia areata, ask your family doctor or members of your local support group to recommend a cosmetologist who specializes in working with persons whose appearance is affected by medical conditions. Is Research Close to Finding Better Treatments or a Cure' While a cure is not imminent, researchers into hair disease are making progress toward a better understanding of the disease. This increased understanding will likely lead the way to better treatments for male or female pattern baldness and in the end a way to prevent or even cure it. Alopecia research ranges from the most basic studies of the mechanisms of hair growth and loss of hair in mice to testing medications and ways to apply medications to help regrow hair in individuals. Both the National Institutes of Health and the National pattern baldness Foundation support research into the baldness science male or female pattern baldness affliction and its treatment. Here are some areas of research that hold promise: Developing an animal model - This is a critical initial step toward understanding the ailment, and much headway has been made. By developing a mouse with a disease similar to human pattern baldness, hair research scientists hope to learn more with reference to the mechanism of the condition and finally develop immune system treatments for the disease in people. Mapping genes - Researchers into hair disease are investigating the possible genetic instigates and mechanism of the affliction both in families that have one or more persons with the ]disease] and in the general population. An understanding of the genetics of the condition will aid in disease prevention, early intervention, and development of specific therapies. Studying hair follicle development - By investigating how hair follicles form in mouse embryos, researchers hope to gain a better understanding of hair cycle biology that may lead to methods of treatment for the underlying ailment process. Targeting the immune system - Several new agents found to be effective in treating psoriasis may prove to be effective in baldness science male or female pattern baldness. These medications work by blocking certain chemical messengers that have a role to play in the immune response, or by interfering with the activity of white blood cells (called T-cells) that are involved in the immune system's assault on hair follicles. New treatments for other autoimmune diseases like rheumatoid arthritis and lupus may also benefit patients with baldness science pattern baldness. Finding better ways to give out drugs - One limitation of current topical therapies is getting the drug to the source of the symptoms, baldness science. Scientists are looking for a compound that penetrates the fat layer under the skin to deliver medication directly to hair follicles. In laboratory animals, topically applied synthetic sacs known as liposomes seem to work. Studies are still needed to show whether liposomes do the same for folks. Understanding cytokines - Chemical messengers called cytokines (baldness science) play a role in regulating the body's immune response, whether it is the normal response to a foreign invader such a virus or an unusual response to a part of the body. Hair research scientists believe that by giving certain inflammation suppressing cytokines, they may be able to slow down or stop the body's abnormal response to the hair follicles. Because giving the cytokines (baldness science) systemically may cause unwanted effects, they believe a topical medication using liposomes to get the media to the root of the hair inside the follicle may be more desirable. Understanding stem cell biology - Epithelial stem cells are immature cells that are responsible for regenerating and maintaining a variety of tissues, including the skin and the hair follicles. Stem cells in the follicle seem to be spared from injury in alopecia areata, which may explain why the potential for re-growth is always there in folks that are affected by the ailment. By studying the biology of these cells, and their immediate children, which seem to be targeted by the immune system, Hair research scientists hope to gain a better understanding of factors that trigger the affliction.
As a footnote, pattern baldness has millions of suffers all over the globe - you are not alone if you are also a sufferer. Keep in mind that many citizens adversely affect their lives in a negative way by focussing on the condition when perhaps they should be concentrating on their lives instead. Most people that meet you will judge you by your general demeanor, your personality and your attitude - not by the quality of hair you have on your head.
