Your dermatologist will examine the area(s) with hair loss carefully and look at your nails. Your dermatologist will also ask some questions. This may be enough to diagnose you. Because there are so many reasons for hair loss, testing is sometimes necessary to make sure alopecia areata is the cause of your hair loss.
Yes, a blood test can diagnose alopecia. Your doctor may order several blood works to determine the cause of the hair loss along with a scalp biopsy.
If you have a medical condition like alopecia areata, the dermatologist may prescribe medications or recommend an over-the-counter treatment. In-office procedures can also be effective for some patients. These treatments can include corticosteroid injections, laser therapy, and platelet-rich plasma therapy.
Physical Exam
A dermatologist examines your scalp to check for inflammation, redness, sores, or scarring. The doctor looks closely at your hair to determine how much is being lost, the pattern of the hair loss, and whether there is hair breakage.
According to Mayo Clinic, if your hair loss is caused by a medical condition, the cost of some treatments might be covered by insurance but in most cases, insurance will not cover hair loss treatment because hair loss is not a medical condition itself.
On the AIP elimination diet, you will avoid grains, legumes, nightshades (such as potatoes and peppers), dairy, eggs, coffee, alcohol, sugar, oil and food additives. After a few months, you can work the excluded foods back in one at a time to figure out which foods trigger an inflammatory reaction.
Causes of Alopecia Areata
In alopecia areata, the immune system mistakenly attacks hair follicles, causing inflammation. Researchers do not fully understand what causes the immune attack on hair follicles, but they believe that both genetic and environmental (non-genetic) factors play a role.
In most people, new hair eventually grows back in the affected areas, although this process can take months. Approximately 50 percent of people with mild alopecia areata recover within a year; however, most people will experience more than one episode during their lifetime.
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.
Other body hair is usually not affected and although hair may feel thinner, it is unlikely that patients would lose all their hair, and in many cases hair would grow back within six months. Alopecia areata on the other hand tends to lead to patches of baldness, usually on the scalp but can be anywhere on the body.
Patchy hair loss (alopecia areata)
In the type of patchy hair loss known as alopecia areata, hair loss occurs suddenly and usually starts with one or more circular bald patches that may overlap.
Female-pattern baldness is a pattern of hair loss (alopecia) caused by hormones, aging and genetics. Unlike male-pattern baldness, female-pattern baldness is an over-all thinning which maintains the normal hairline.
Most people know alopecia to be a form of hair loss. However, what they don't always know is that there are three main types of the condition – alopecia areata, alopecia totalis and alopecia universalis.
The extent of alopecia (how much hair has fallen out) varies and links to the different subtypes. Some said their hair loss involved one small patch about the size of a 1p coin which regrew after a few weeks or months. Others developed more patches which sometimes joined up into bigger bald areas over time.
On June 13, 2022, the FDA approved the first systemic treatment for severe alopecia areata: the oral tablet baricitinib (Olumiant). Without insurance coverage, baricitinib costs around $2,500 and $5,000 per month for 2-mg or 4-mg tablets, respectively.
There is currently no cure for alopecia areata, although there are some forms of treatment that can be suggested by doctors to help hair re-grow more quickly. The most common form of alopecia areata treatment is the use of corticosteroids, powerful anti-inflammatory drugs that can suppress the immune system.
Traditional treatments for alopecia areata include steroid injections to the areas where the hair has been shed. Steroids suppress the immune cells that are attacking hair follicles, so hair can regrow.
A variety of factors are thought to cause alopecia areata (al-o-PEE-she-uh ar-e-A-tuh), possibly including severe stress. With alopecia areata, the body's immune system attacks the hair follicles — causing hair loss.
Calcipotriol, a vitamin D analog, has been reported to be topically used in treating alopecia areata with promising results. Combination therapy of vitamin D analogs with corticosteroids might also be used in treating alopecia areata.
Alopecia areata (AA) occurs when the immune system attacks the hair follicle. Studies have shown a relationship between AA and low vitamin D levels. Vitamin D should be supplemented if levels are low.
Bright colored fruits and vegetables contain antioxidants that help reduce inflammation. These include apples, strawberries, blueberries, raspberries, pineapple, cherries, broccoli, cauliflower, spinach and green cabbage. And with these, symptoms of alopecia areata might also improve. This contains many antioxidants.
How Long does Hair Loss Last? In half of patients with alopecia areata, individual episodes of hair loss last less than one year, and hair grows back without treatment. These patients may experience recurrent episodes of hair loss that spontaneously regrow or respond quickly to treatments.
The currently preferred treatment for androgenetic alopecia is topically administered 2 percent minoxidil. Minoxidil appears to affect the hair follicle in three ways: it increases the length of time follicles spend in anagen, it “wakes up” follicles that are in catagen, and it enlarges the actual follicles.
