Alopecia areata
What Is alopecia areata' 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, alopecia areata. This can lead to loss of hair on the scalp and other sites on the body. In most situations, hair falls out in tiny, round patches about two square centimetres. In many cases, the affliction does not cover more than a couple of patches. In some folks, hair loss is more extensive. Although uncommon, alopecia areata, the ailment can carry on to to instigates 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 male or female pattern baldness, immune system cells called white blood cells attack the speedily growing cells in the hair follicles that make the hair.
The problem hair follicles become small and drastically inhibit hair production. Fortunately, the stem cells that continually supply the follicle with new cells do not seem to be targeted. and therefore the follicle always has the potential to regrow hair - alopecia areata. Researchers do not know precisely why the hair follicles undergo these changes, alopecia areata but they are fairly certain that a combination of genes may predispose some individuals to the disease. In those who are genetically predisposed, some type of trigger - perhaps a virus or an element in the person's environment - brings on the assault against the hair follicles. Who Is Most Likely To Get It' male or female pattern baldness seriously affects around 4 million US citizens of both sexes and of all ages and ethnic backgrounds. It often starts in childhood alopecia areata. If you have a close relation with the condition, your risk of developing it is slightly increased. If your relative lost his or her initial patch of hair before their early thirties, the risk to other family members is greater. Overall, one in five people that are afflicted with the affliction have a relative who has it too. Is My alopecia areata a Symptom of a Serious Disease' pattern baldness is not a life-threatening disease and neither is alopecia areata. It does not cause any physical pain, and persons that have the ailment are generally in good health otherwise. But for most folk, a condition that unpredictably affects their appearance the way alopecia areata does is a serious matter. The effects of male or female pattern baldness are primarily socially and emotionally 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 eyes, nose, and ears. pattern baldness often occurs in citizens whose family members have other autoimmune ailments, such as Addison's disease, systemic lupus erythematosus, rheumatoid arthritis, thyroid disease, pernicious anemia or diabetes or even alopecia areata. People who have male or female pattern baldness do not by and large have other autoimmune afflictions, but they do tend to have a higher occurrence of thyroid disease, nasal allergies, atopic eczema and asthma, alopecia areata. Can I Pass It on to My Children' It is possible, but not likely, for pattern baldness to be inherited. Most children with alopecia areata do not have a mom or dad with the condition, and the vast majority of parents with male or female pattern baldness do not pass it along to their children. alopecia areata is not like some genetic ailments in which a child has a fifty fifty chance of developing the affliction if one parent has it. Researchers into hair disease believe that there may be a number of genes that predispose certain people to the disease. It is highly unlikely that a child would inherit all of the genes needed 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 fifty five percent. In other words, if one twin has the disease, there is only a 55 percent chance that the other twin will have it as well. This shows that other considerations besides genetics are neccessary to trigger the ailment. To learn more with regard to the genes and other factors involved in male or female pattern baldness risk, the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) is funding an pattern baldness registry alopecia areata. The registry is a controlled network of five centers throughout the United States of America that will identify and register patients that are affected by the affliction and collect data and blood samples (which contain genes). Data, including genetic information, will be made available to scientists investigating the genetic basis 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 grow back are extremely good, but it may also fall out again however. Unfortunately, it's impossible to predict whether it might fall out or regrow. The course of the condition varies from person to person. Some folks lose just a few patches of hair, alopecia areata then the hair grows back and the disease never comes back. Other persons continue to lose and regrow hair for many years. A few individuals lose all the hair on their head; others lose all the hair on their head, face and body. Even for those unfortumate individuals who lose all their hair, 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 eventually the same color and texture as the original hair. What Can I Expect Next' The course of alopecia areata is highly unpredictable, and the uncertainty of what will happen next is probably the most frustrating and difficult effect of the disease. You may continue to lose hair, or your alopecia may stop, alopecia areata. Your lost hair could grow back but it may not and you may or may not continue to develop new bare patches. How Is It Treated' [While there is neither a cure for pattern baldness nor drugs approved for its treatment], some individuals find that drugs approved for other purposes like pattern baldness can help hair grow back, alopecia areata at least in the short term. The following are some methods of treatment for male or female pattern baldness. Keep in mind that while these treatments may promote hair growth, none of them prevent new patches or in fact cure the underlying affliction. Consult your health care professional with reference to the best choice for you. Corticosteroids - Corticosteroids are powerful anti-inflammatory drugs, alopecia areata, 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 various autoimmune diseases, including alopecia areata. Corticosteroids may be administered in 3 ways for alopecia areata:
Local innoculations - Injections of steroids directly into hairless patches on the scalp and occasionally the brow and beard areas are effective in hair growth in most citizens. It habitually takes about one month for new hair growth to become visible. Injections deliver small 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 passing pain, mild swelling, and sometimes changes in pigmentation, as well as tiny indentations in the skin that go away when innoculations are halted. Because injections can be painful, they may not be the preferred treatment for children. After 4 to 8 weeks, new hair growth customarily becomes visible, and the injections commonly 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 quantity 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 alopecia areata. But because of the risk of side effects of oral corticosteroids, such as hypertension, alopecia areata and cataracts, they are used only occasionally for male or female pattern baldness and for shorter periods of time. Topical ointments - ointments or creams containing steroids rubbed directly onto the affected area are less traumatic than innoculations and, therefore, are occasionally preferred for children. However, corticosteroid ointments and creams in isolation are less effective than innoculations; 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 occurs in about 3 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 satisfactory. Anthralin (Psoriatec) - Anthralin, a synthetic tar-like substance that changes immune function in the problem skin, is an approved treatment for psoriasis. Anthralin is also commonly used to treat pattern baldness. Anthralin is applied for 20 to 60 minutes ("short contact therapy") to avoid skin irritation, alopecia areata which is not appropriate for the drug to work. When it works, new hair growth is usually evident in two to three months. Anthralin is often used in combination with other treatments, such as corticosteroid injections 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 male or female pattern baldness. Topical sensitizers - Topical sensitizers are medicines that, when applied to the scalp, start an allergic reaction that leads to itching, scaling, and eventually hair growth. If the medication works, new hair growth is generally established in three to twelve months. Two topical sensitizers are used in alopecia areata: squaric acid dibutyl ester (SADBE) and diphenylcyclopropenone (DPCP). Their safety and consistency of formula are currently under review. Oral cyclosporine - Originally developed to keep folks's immune systems from rejecting transplanted organs, oral cyclosporine is sometimes used to suppress the immune system response in psoriasis and other immune-mediated skin conditions. But suppressing the immune system can also cause problems, including an increased risk of serious infection and possibly skin cancer. Although oral cyclosporine may regrow hair in alopecia areata, it does not turn the ailment off. Most doctors feel the dangers of the drug outweigh its benefits for pattern baldness and alopecia areata. Photochemotherapy - In photochemotherapy, a treatment used most commonly for psoriasis, a person is given a light-sensitive drug known as a psoralen either orally or topically given and then exposed to an ultraviolet light source. This combined treatment is called PUVA. In clinical trials, around 55 percent of persons 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 takes the risk of developing skin cancer. Alternative therapies - When drug treatments fail to bring enough hair regrowth, some citizens turn to alternative therapies - alopecia areata. Alternatives purported to help male or female pattern baldness include Chinese herbs, zinc and vitamin supplements, acupuncture, aroma therapy, and evening primrose oil. Because many other types of therapies are not backed by clinical trials, they may or may not be effective for regrowing hair. In fact, some may actually make hair loss worse. Furthermore, just because these therapies are natural does not mean that they are safe to employ. As with any therapy, it is best to discuss these methods of treatment with your physician before you employ them.
In addition to treatments to help hair grow, there are steps that can be taken to lessen the physical dangers or discomforts of losing one's hair. Sunscreens are important for the scalp, face, and all areas of the body that are exposed. Eyeglasses (or sunglasses) protect the eyes from excessive sun rays, and from dust and debris, when eyebrows or eyelashes are missing. Hairpieces, caps, or scarves protect the scalp from sunlight and keep the head warm. Antibiotic ointment applied inside the nostrils can help to protect against organisms invading the nose when nostril hair is missing.
How Will pattern baldness Affect My Life and Lifestyle' This is a common question, particularly for children, teenagers and young adults who are beginning to formulate lifelong aims and who may live with the effects of male or female pattern baldness for many years, alopecia areata. The great news is that male or female pattern baldness is not a painful condition and does not make individuals feel sick physically. It is not contagious, and people who have the alopecia areata disease are generally healthy 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 loss of hair, however, can be a challenge. Many individuals cope by learning as much as they can with reference to the affliction; speaking with others who are facing the same problems; and, if necessary, seeking counseling to help build a positive self-image. To take account of quality-of-life issues for alopecia areata, alopecia areata and all other skin ailments, the NIAMS sponsored a scientific meeting in September 2002 on the toll of skin diseases. How Can I Deal With With the Effects of This Disease' Living with alopecia can be hard, especially in a culture that sees hair as a sign of youthfulness and good health. Even so, most people with alopecia areata are well-adjusted, contented citizens living full lives. The key to coping is valuing yourself for who you are, not for how much hair you have or dont have. Many persons learning to deal with pattern baldness find it helpful to talk with other folks who are dealing with the same problems. In excess of 4 million people nationwide have this condition at some point in their lives, so always remember that you are not alone. If you would like to be in touch with others with the disease, 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 several situations across the country. An alternative way to cope with the affliction is to minimize its effects on your appearance. If you happen to have total baldness, a wig or hairpiece can look natural and stylish. For small patches of hair loss, a hair colored powder, cream or crayon applied to the scalp can make baldness less obvious by getting rid of the contrast between the hair and the scalp. Skilfully applied alopecia areata eyebrow pencil can mask missing eyebrows. Children with pattern baldness may prefer to wear bandanas, scarves or caps. There are many types available to suit a child's interest and mood - many even have ponytails fixed on to them with alopecia areata. For women, attractive scarves can hide patchy alopecia; jewelry and clothing can distract attention from patchy hair; and proper makeup can mask the effects of lost facial hair. If you would like to learn more about camouflaging the cosmetic effects of alopecia areata male or female pattern baldness, ask your family doctor or members of your local support group to recommend a cosmetologist who specializes in working with folks whose appearance is problem 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 ailment. This increased understanding will likely lead the way to better methods of treatment for male or female pattern baldness and ultimately 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 drugs to help regrow hair in individuals. Both the National Institutes of Health and the National alopecia areata Foundation support research into the alopecia areata male or female pattern baldness condition and its treatment. Here are some areas of research that hold promise: Developing an animal model - This is a critical first step toward understanding the ailment, and much headway has been made. By developing a mouse with a affliction similar to human alopecia areata, researchers hope to learn more with reference to the mechanism of the disease and finally develop immune system treatments for the ailment in persons. Mapping genes - Scientists are studying the possible genetic causes and mechanism of the condition both in families that have one or more persons with the ]disease] and in the general population. An understanding of the genetics of the affliction will aid in disease prevention, early intervention, and development of specific therapies. Studying hair follicle development - By studying how hair follicles form in mouse embryos, hair research scientists hope to gain a better understanding of hair cycle biology that may lead to methods of treatment for the underlying disease process. Targeting the immune system - Several new media found to be effective in treating psoriasis may prove to be effective in alopecia areata pattern baldness. These medications work by blocking certain chemical messengers that play a role in the immune response, or by interfering with the activity of white blood cells (known as T-cells) that are involved in the immune system's attack on hair follicles. New treatments for other autoimmune diseases like rheumatoid arthritis and lupus may also benefit patients with alopecia areata alopecia areata. Finding better ways to give out drugs - One limitation of current topical therapies is getting the drug to the source of the symptoms, alopecia areata. Hair research 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 called liposomes seem to fill the bill. Studies are still required to show whether liposomes do the same for citizens. Understanding cytokines - Chemical messengers known as cytokines (alopecia areata) play a role in regulating the body's immune response, whether it is the standard response to a foreign invader such a virus or an abnormal response to a part of the body. Hair research scientists believe that by giving certain cytokines that inhibit inflammation, they may be able to impede or stop the body's unusual response to the hair follicles. Because giving the cytokines (alopecia areata) systemically may instigates unwanted effects, they believe a topical medication using liposomes to get the agents to the root of the hair inside the follicle may be better. Understanding stem cell biology - Epithelial stem cells are immature cells that are responsible for regenerating and maintaining a variety of tissues, including the hair follicles and the skin. Stem cells in the follicle appear to be spared from injury in pattern baldness, which may explain why the potential for re-growth is always there in persons with the condition. By investigating the biology of these cells, and their immediate offspring, which seem to be targeted by the immune system, Hair research scientists hope to gain a better understanding of factors that trigger the disease.
To wrap it up, alopecia areata has millions of suffers around the world - you are not alone if you are also a sufferer. Keep in mind that many people seriously affect their lives in a negative way by concentrating on the ailment when perhaps they should be focussing on their lives instead. Almost all of the people that you come across will judge you by your attitude, your general demeanor and your personality - not by how much hair you have on your head.
