Hair Loss Information Page Due to hormonal changes, irritation or damage, some hair follicles have a shorter growth phase and produce thinner, shorter hair shafts. Your hair goes through a cycle of growth and rest. The course of each cycle varies by individual. But in general, the growth phase of scalp hair, known as anagen, typically lasts two to three years. During this time, your hair grows just less than 1/2 inch (1 centimeter) a month. The resting phase is called telogen. This phase typically lasts three to four months. At the end of the resting phase, the hair strand falls out and a new one begins to grow in its place. Once a hair is shed, the growth stage begins again. Most people normally shed 50 to 100 hairs a day. But with about 100,000 hairs in the scalp, this amount of hair loss shouldn't cause noticeable thinning of the scalp hair. Gradual thinning is a normal part of aging. However, hair loss may lead to baldness when the rate of shedding exceeds the rate of regrowth, when new hair is thinner than the hair shed or when hair comes out in patches. Causes of specific types of hair loss - Pattern baldness (androgenetic alopecia). In male- and female-pattern baldness, the time of growth shortens, and the hairs are not as thick or sturdy. With each growth cycle, the hairs become rooted more superficially and more easily fall out. Heredity likely plays a key role. A history of androgenetic alopecia on either side of your family increases your risk of balding. Heredity also affects the age at which you begin to lose hair and the developmental speed, pattern and extent of your baldness.
- Cicatricial (scarring) alopecia. This type of permanent hair loss occurs when inflammation damages and scars the hair follicle. This prevents new hair from growing. This condition can be seen in several skin conditions, including lupus erythematosus or lichen planus. It's not known what triggers or causes this inflammation.
- Alopecia areata. This is classified as an autoimmune disease, but the cause is unknown. People who develop alopecia areata are generally in good health. A few people may have other autoimmune disorders, including thyroid disease. Some scientists believe that some people are genetically predisposed to develop alopecia areata and that a trigger, such as a virus or something else in the environment, sets off the condition. A family history of alopecia areata makes you more likely to develop it. With alopecia areata, your hair generally grows back, but you may lose and regrow your hair a number of times.
- Telogen effluvium. This type of hair loss is usually due to a change in your normal hair cycle. It may occur when some type of shock to your system — emotional or physical — causes hair roots to be pushed prematurely into the resting state. The affected growing hairs from these hair roots fall out. In a month or two, the hair follicles become active again and new hair starts to grow. Telogen effluvium may follow emotional distress, such as a death in the family or a physiological stress, such as a high fever, sudden or excessive weight loss, extreme diets, nutritional deficiencies, surgery, or metabolic disturbances. Hair typically grows back once the condition that caused it corrects itself, but it usually take months.
- Anagen Effluvium Anagen effluvium occurs after any insult to the hair follicle that impairs its mitotic or metabolic activity. This hair loss is commonly associated with chemotherapy. Since chemotherapy targets your body’s rapidly dividing cancer cells, your body’s other rapidly dividing cells such as hair follicles in the growing (anagen) phase, are also greatly affected. Soon after chemotherapy begins approximately 90 percent or more of the hairs can fall out while still in the anagen phase. The characteristic finding in anagen effluvium is the tapered fracture of the hair shafts. The hair shaft narrows as a result of damage to the matrix. Eventually, the shaft fractures at the site of narrowing and causes the loss of hair.
- Traction alopecia. Excessive hairstyling or hairstyles that pull your hair too tightly cause traction alopecia. If the pulling is stopped before there's scarring of your scalp and permanent damage to the root, hair usually grows back normally.
- Andogenetic Alopecia The majority of women with androgenic alopecia have diffuse thinning on all areas of the scalp. Men on the other hand, rarely have diffuse thinning but instead have more distinct patterns of baldness. Some women may have a combination of two pattern types. Androgenic alopecia in women is due to the action of androgens, male hormones that are typically present in only small amounts. Androgenic alopecia can be caused by a variety of factors tied to the actions of hormones, including, ovarian cysts, the taking of high androgen index birth control pills, pregnancy, and menopause. Just like in men the hormone DHT appears to be at least partially to blame for the miniaturization of hair follicles in women suffering with female pattern baldness. Heredity plays a major factor in the disease.
Other causes of hair loss - Poor nutrition. Having inadequate protein or iron in your diet or poor nourishment in other ways can cause you to experience hair loss. Fad diets, crash diets and certain illnesses, such as eating disorders, can cause poor nutrition. Wiggin Out Salon recomends that you should see an alternative doctor that specializes in Integrative Medicine and medical acupuncture.

- Medical treatments. Undergoing chemotherapy or radiation therapy may cause you to develop alopecia. Under these conditions, healthy, growing (anagen) hairs can be affected. After your treatment ends, your hair typically begins to regrow.
- Hormonal changes. Hormonal changes and imbalances can cause temporary hair loss. This could be due to pregnancy, childbirth, discontinuation of birth control pills, the onset of menopause, or an overactive or underactive thyroid gland. The hair loss may be delayed by three months following a hormonal change, and it'll take another three months for new hair to grow back. During pregnancy, it's normal to have thicker, more luxuriant hair. It's also common to lose more hair than normal about three months after delivery. If a hormonal imbalance is associated with an overproduction of testosterone, there may be a thinning of hair over the crown of the scalp. Correcting hormonal imbalances may stop hair loss.

- Hair treatments. Chemicals used for dying, tinting, bleaching, straightening or permanent waves can cause hair to become damaged and break off if they are overused or used incorrectly. Overstyling and excessive brushing also can cause hair to fall out if the hair shaft becomes damaged.
- Scalp infection. Infections, such as ringworm, can invade the hair and skin of your scalp, leading to hair loss. Once infections are treated, hair generally grows back. Ringworm, a fungal infection, can usually be treated with a topical or oral antifungal medication.
- Trichotillomania (hair-pulling disorder). Trichotillomania is a type of mental illness in which people have an irresistible urge to pull out their hair, whether it's from the scalp, their eyebrows or other areas of the body. Hair pulling from the scalp often leaves them with patchy bald spots on the head, which they may go to great lengths to disguise. Causes of trichotillomania are still being researched, and no specific cause has yet been found.
Symptoms The medical term for hair loss is alopecia. Pattern baldness (androgenetic alopecia), the most common type of alopecia, affects roughly one-third of men and women. It's typically permanent. Other types of alopecia are temporary, including alopecia areata. It can involve hair loss on your scalp or other parts of your body. Permanent hair loss - Male-pattern baldness (androgenetic alopecia). For men, pattern baldness can begin early, even in the teens or early 20s. It's typically characterized by a receding hairline at the temples and balding at the top of the head. The end result may be partial or complete baldness.
- Female-pattern baldness (androgenetic alopecia). Women with permanent hair loss usually have hair loss limited to thinning at the front, sides or crown. Women usually maintain their front hairline and rarely experience complete baldness.
- Cicatricial (scarring) alopecia. This rare condition occurs when inflammation damages and scars hair follicles, causing permanent hair loss. Sometimes the patchy hair loss is associated with itching or pain.
Temporary hair loss - Alopecia areata. Hair loss usually occurs in small, round, smooth patches about the size of a quarter. Usually the disease doesn't extend beyond a few bare patches on the scalp, but it can cause patchy hair loss on any area that has hair, including eyebrows, eyelashes and beard. In rare cases, it can progress to cause hair loss over the entire body. If the hair loss includes your entire scalp, the condition is called alopecia totalis. If it involves your whole body, it's called alopecia universalis. Soreness and itching may precede the hair loss, but symptoms are often minimal.
- Telogen effluvium. This type of temporary hair loss occurs suddenly, most often after a significant illness or major life stress. Handfuls of hair may come out when combing or washing your hair or may fall out after gentle tugging. This type of hair loss usually causes overall hair thinning and not bald patches.
- Traction alopecia. Bald patches can occur if you regularly wear certain hairstyles, such as pigtails, braids or cornrows, or if you use tight rollers. Hair loss typically occurs between the rows or at the part where hair is pulled tightly.
- Anagen effluvium. In this type of hair loss, actively growing hairs in the anagen state are affected most often by chemotherapeutic drugs given to fight cancer or lymphoma. Hair loss starts soon after beginning therapy and is more extensive than in the telogen effluvium state. In the weeks after the therapy has been completed, the hair cycles re-establish themselves, although the hair may not return as thickly as before chemotherapy.
When to see a doctor Talk to your doctor if you notice sudden or patchy hair loss or more than usual hair loss when combing or washing your hair. Sudden hair loss can signal an underlying medical condition and may require medical treatment. No cure is available for permanent hair loss or baldness. However, you can talk to your doctor about medical treatments to slow the rate of hair loss or to hide hair loss. Preparing for your appointment with your doctor. You're likely to start by first seeing your family doctor or a general practitioner or alternative means like a doctor that has a nutritional background. Because appointments can be brief, and because there's often a lot of ground to cover, it's a good idea to be well prepared for your appointment. Here's some information to help you get ready for your appointment, and what to expect from your doctor. What you can do - Be aware of any pre-appointment restrictions. At the time you make the appointment, be sure to ask if there's anything you need to do in advance, such as restricting your diet.
- Write down any symptoms you're experiencing, including any that may seem unrelated to the reason for which you scheduled the appointment.
- Write down key personal information, including any major stresses or recent life changes.
- Make a list of all medications, as well as any vitamins or supplements, that you're taking.
- Take a family member or friend along, if possible. Sometimes it can be difficult to soak up all the information provided to you during an appointment. Someone who accompanies you may remember something that you missed or forgot.
- Write down questions to ask your doctor.
Your time with your doctor is limited, so preparing a list of questions will help you make the most of your time together. List your questions from most important to least important in case time runs out. For hair loss, some basic questions to ask your doctor include: - What is likely causing my symptoms or condition?
- Are there other possible causes for my symptoms or condition?
- What kinds of tests do I need?
- Is my condition likely temporary or chronic?
- What is the best course of action?
- What are the alternatives to the primary approach that you're suggesting?
- I have these other health conditions. How can I best manage them together?
- Are there any restrictions that I need to follow?
- Should I see a specialist? What will that cost, and will my insurance cover seeing a specialist?
- Is there a generic alternative to the medicine you're prescribing me?
- Are there any brochures or other printed material that I can take home with me? What Web sites do you recommend?
In addition to the questions that you've prepared to ask your doctor, don't hesitate to ask questions during your appointment at any time that you don't understand something. What to expect from your doctor Your doctor is likely to ask you a number of questions. Being ready to answer them may reserve time to go over any points you want to spend more time on. Your doctor may ask: - When did you first begin experiencing hair loss?
- Has your hair loss been continuous or occasional?
- Have you had a similar problem in the past?
- Has anyone in your immediate family experienced alopecia?
- What, if anything, seems to improve your hair loss?
- What, if anything, appears to worsen your hair loss?
