A board-certified dermatologist can often diagnose this disease by looking carefully at the area(s) with hair loss and your nails. Thanks to newer treatments, some people who weren’t helped by previous treatments are regrowing their hair. With treatment, it’s possible to see some regrowth in 6 weeks. Camouflaging hair loss can be helpful for patients who decide against pharmacological treatment or in those who have incomplete response.
Health Alerts from Harvard Medical School
The course of alopecia areata varies from person to person. Some have bouts of hair loss throughout their lives, while others only have one episode. Recovery is unpredictable too, with hair regrowing fully in some people but not others. In some people, their hair grows back but falls out again later. In others, their hair grows back and never falls out again. Even if someone loses all of their hair, there’s a chance that it’ll grow back.
How do clinical features vary in differing types of skin?
These dermatologists' tips tell you how to protect your skin. Both the CDC and the FDA warn against treating this common childhood condition on your own with non-prescription treatments. Nail changes such as ridges and pits occur in some people, especially those who have hair loss over more parts of their body. NAAF supports research to find a cure or acceptable treatment for alopecia areata, supports those with the disease, and educates the public about alopecia areata. Alopecia areata is a polygenic disease, meaning it is related to multiple genetic factors.
What medical treatments are available for alopecia areata?
Although this condition is less common in women, 38% of women older than 70 years may be affected3 (Figure 24 ). Many patients with androgenetic alopecia have a family history of this condition. Prescription medications, like finasteride (Propecia), may help prevent further androgenetic hair loss, especially for male pattern baldness. You take this medication daily to slow hair loss, though some experience new hair growth when taking finasteride.

If Your Hair Grows Back
Hair typically falls out in small, round patches about the size of a quarter. Anyone at any age can develop alopecia areata and it does often start in childhood. Parenting a child with the disease can be challenging. To learn about children with alopecia areata and issues related to parenting them, click here. If you have an autoimmune disease, your body’s immune system mistakes your healthy tissues as dangerous and begins attacking them.
Depending on the severity of the disease, treatments for alopecia areata are effective but can take 3 to 5 months to show results, says Dr. Costello. For those receiving treatment by topical injections, it can take 3 to 4 months to know whether they have worked. For adults and older children, injecting steroids into the scalp can cause hair growth. However, these injections can lead to tenderness and you may need to receive several rounds of injections 4 to 6 weeks apart.
Thinning hair in women can occur at any age and can take different forms, such as minor thinning on the crown of the head or complete baldness. On the whole, it’s important that you speak with your doctor about any symptoms you’re experiencing. A dermatologist can provide a proper diagnosis, and select a personalized treatment that will help restore health to you hair and scalp.
Alopecia Areata Is Different for Everyone
Alopecia areata can be triggered by a recent illness, like a viral infection, or by taking certain medications for other medical conditions. Some people can link the onset of their alopecia to a stressful life event but many can't. Sometimes it seems to run in families and it has been known to come on in twins at the same time. The typical pattern is for one or more bald patches to appear on the scalp.
In some cases, a biopsy is needed to confirm the diagnosis. “When we do a biopsy, we’re looking for immune cells around the base of the hair follicle in order to make the diagnosis,” says Dr. King. Once your dermatologist has all the necessary information, you’ll find out if you have alopecia areata. If you do, your dermatologist will talk with you about how the disease is affecting your life and whether treatment is recommended. Some people who lose their hair, regrow it, and never have another episode. This is more common when someone has a few patches of hair loss.
The resulting inflammation seems to subvert the immune system’s attack on the hair follicles. However, this treatment is often uncomfortable for the patient, causing redness and itchiness. If you’re unhappy with the regrowth, your dermatologist may prescribe medication that you apply to the areas that need more regrowth.
Patients may present to their family physician first with diffuse or patchy hair loss. Scarring alopecia is best evaluated by a dermatologist. Nonscarring alopecias can be readily diagnosed and treated in the family physician's office.
Minimize the use of high-heat styling tools, hair extensions and harsh treatments like perms. Avoid hairstyles like tight buns and braids that pull on your scalp, potentially causing traction alopecia. Alopecia areata will go into remission for many people. But they may have a recurrence — meaning they will experience hair loss again — in the future. About 10% of individuals will have more widespread involvement and may need long-term treatment to grow back their hair and maintain the improvement.
Occasionally tests might be advised to check for other autoimmune diseases. For example, if there are certain other symptoms, blood tests might be used to check blood count and thyroid function. Usually blood tests come back entirely normal with alopecia areata. The diagnosis is usually based on the typical appearance of the bald patches.
Losing a certain amount of hair everyday is considered normal. It is thought we shed around 50 to 100 hairs naturally throughout the day. If you need help finding a primary care doctor, then check out our FindCare tool here.
You may have bouts of hair loss here and there or you may have it your whole life. With alopecia areata, you may lose hair on your scalp, face, or other parts of your body. Finally, keep in mind that the same healthy habits recommended for maintaining your physical health will also help your hair.
Some wear wigs or use camouflage techniques to hide the bald areas, while others don’t bother hiding it at all.
