Alopecia Areata

There’s no known cure for alopecia areata, but there are treatments that you can try that might be able to slow down future hair loss or help hair grow back more quickly.

The condition is difficult to predict, which means it may require a large amount of trial and error until you find something that works for you. It’s also important to remember that treatment isn’t always successful. Some people may continue to have hair loss, even with treatment.

Medical treatments

Topical agents

You can rub medications into your scalp to help stimulate hair growth. A number of medications are available, both over the counter (OTC) and by prescription:

• Minoxidil (Rogaine) has OTC availability, and while it’s commonly used, it is not FDA approved for alopecia areata. Before applying it to areas such as the scalp, eyebrows, and beard, you should speak with a healthcare professional. There’s only evidence that it’s useful for people with limited alopecia areatae. It generally takes about 4–6 months, or longer, to see results.
• Anthralin (Dritho-Scalp) is a drug that irritates the skin to spur hair regrowth.
• Corticosteroid creams such as clobetasol (Impoyz), foams, lotions, and ointments are thought to work by decreasing inflammation in the hair follicle.
• Topical immunotherapy is a technique in which a chemical like diphencyprone is applied to the skin to spark an allergic rash. The rash, which resembles poison oak, may induce new hair growth within 6 months. However, though repeat treatment may be necessary, it isn’t ordinarily done indefinitely.

Injections

Steroid injections are a common option for mild, patchy alopecia to help hair grow back on bald spots. Tiny needles inject the steroid into the bald area.

The treatment has to be repeated every 1 to 2 months to regrow hair. It does not prevent new hair loss from occurring.

Oral treatments

Cortisone tablets are sometimes used for extensive alopecia, but due to the possibility of side effects, you should discuss this option with a doctor.

Oral immunosuppressants, like methotrexate and cyclosporine, are another option you can try. They work by blocking the immune system’s response, but they cannot be used for a long period of time due to the risk of side effects, such as high blood pressure, liver and kidney damage, and an increased risk of serious infections and a type of cancer called lymphoma.

Laser and Light therapy

Light therapy is also called photochemotherapy, which uses a light sensitizer, or phototherapy, which uses specific wavelengths of ultraviolet light for their healing effects. Laser treatment delivers specific doses of radiation to encourage new hair growth. Both therapies are considered safe and effectiveTrusted Source.

Natural treatment

Some people with alopecia areata choose alternative therapies to treat the condition. However, it’s important to know that these are all experimental. They have not been tested in clinical trials, and there is no solid medical or scientific evidence to show that they’re effective.

Natural and alternative treatments include acupuncture, aromatherapy, vitamins and supplements (including zinc and biotin), essential oils and other oils (such as coconut, tea tree, and castor oil), onion juice rubbed onto the scalp, and probiotics.

There is some evidence that changes to diet 

Some individuals with a diagnosed autoimmune condition may consider following an anti-inflammatory diet. This type of eating plan is designed to help reduce the body’s autoimmune response and the chances of another hair loss episode or further hair loss.

On this diet, you eat foods that are known to ease the inflammation process. The foundational foods of this diet, also known as the autoimmune protocol, are fruits and vegetables like blueberries, nuts, seeds, broccoli, beets, and lean meats like wild-caught salmon.

Some studies have also shown that  may have a positive effect on alopecia areata.

Eating a balanced diet — one with whole grains, fruits, vegetables, and lean meat — is beneficial to your overall health for many reasons, not just for reducing inflammation.

Alopecia areata is an autoimmune condition. An autoimmune condition develops when the immune system mistakes healthy cells for foreign substances. Normally, the immune system defends your body against foreign invaders, such as viruses and bacteria.

However, if you have alopecia areata, your immune system mistakenly attacks your hair follicles. Hair follicles are the structures from which hairs grow. When the follicles become smaller and stop producing hair, it leads to hair loss.

Researchers don’t know the exact cause of this condition. Some possible risk factors have been identified, including:

• genetics, such as a close family member with alopecia areata
• having certain health conditions, such as Down’s Syndrome, thyroid disease, or vitiligo
• vitamin D deficiency

There is also a condition known as nivolumab-induced alopecia areata. This occurs in people who are being treated with the cancer drug nivolumab. In these cases, hair loss is a sign that the drug is working.

The main symptom of alopecia areata is hair loss. Hair usually falls out in patches on the scalp. These patches are often several centimeters or less.

Hair loss might also occur on other parts of the face, like the eyebrows, eyelashes, and beard, as well as other parts of the body. Some people lose hair in a few places. Others lose it in multiple spots.

You may first notice clumps of hair on your pillow or in the shower. If the spots are on the back of your head, someone may bring it to your attention. However, other health conditions can also cause hair to fall out in a similar pattern. Hair loss alone is not used to diagnose alopecia areata.

In rare cases, some people may experience more extensive hair loss. This is usually an indication of another type of alopecia, such as:

• alopecia totalis, which is the loss of all hair on the scalp
• alopecia universalis, which is the loss of all hair on the entire body

Doctors might avoid using the terms “totalis” and “universalis” because some people may experience a degree of hair loss between the two conditions. For example, it’s possible to lose all hair on the arms, legs, and scalp, but not on the chest.

The hair loss associated with alopecia areata is unpredictable, and as far as doctors and researchers can tell. The hair may grow back at any time and then may fall out again. The extent of hair loss and regrowth varies greatly from person to person.

Children can develop alopecia areata. However typical onset is between 25 and 36 years old.

While there is some hereditary component to alopecia areata, parents with the condition don’t always pass it on to their children. Likewise, children with this type of hair loss may not have a parent who has it.

In addition to hair loss, children may experience nail defects, such as pitting or lesions. Adults may experience this additional symptom, too, but it’s likely more common in children.

According to the NAAF, children younger than 5 years old typically don’t experience much of an emotional impact from alopecia. However, after age 5, hair loss can be traumatizing for young children as they start noticing differences in their hair compared with others.

If your child appears stressed or depressed, ask a pediatrician about supportive resources like recommending a counselor experienced in working with children.

Several types of alopecia areata exist. Each type is characterized by the extent of hair loss and other symptoms you may be experiencing. Each type may also have a slightly different treatment and prognosis.

Alopecia areata (patchy)

The main characteristic of the patchy type of alopecia areata is one or more coin-sized patches of hair loss on the skin or body. If this condition expands, it may become alopecia totalis or alopecia universalis.

Alopecia totalis

Alopecia totalis occurs when you have hair loss across the entire scalp.

Alopecia universalis

In addition to losing hair on the scalp, people with alopecia universalis also lose all hair on the face — eyebrows and eyelashes. Alopecia universalis causes total body hair loss.

Diffuse alopecia areata

Also called alopecia areata incognitaTrusted Source, diffuse alopecia areata may look a lot like female- or male-pattern hair loss. It results in sudden and unexpected thinning of hair all over the scalp, not in just one area or patch.

Ophiasis alopecia

Hair loss that follows a band along the sides and lower back of the scalp is called ophiasis alopecia.

A doctor may be able to diagnose alopecia areata simply by looking at the extent of your hair loss and examining a few hair samples under a microscope.

Your doctor may order a scalp biopsy to rule out other conditions that cause hair loss, including fungal infections like tinea capitis. During a scalp biopsy, the healthcare professional will remove a small piece of skin on your scalp for analysis.

Blood tests might be ordered if the doctor suspects other autoimmune conditions.

The specific blood test performed depends on the particular disorder the doctor suspects.

However, a doctor will likely order tests to check for the presence of one or more abnormal antibodies. If these antibodies are found in your blood, it may mean that you have an autoimmune disorder. Depending on findings, additional tests may be ordered to rule out other conditions, such as thyroid problems or hormonal imbalances.

If you’re experiencing hair loss, speak with a doctor to learn more and find out what treatment options are available.
