In its most common form, alopecia areata causes small round or oval patches of baldness on the scalp. The area of bald skin looks smooth and normal. In most cases, there are no other scalp symptoms. Occasionally, there is mild itching, tingling, tenderness or a burning sensation in the affected area.
Alopecia areata is a condition that causes your hair to fall out in patches. These patches may connect and then become more noticeable. The condition develops when your immune system attacks the hair follicles causing hair loss.
Bald spots of the scalp, brow, or beard are commonly caused by a medical condition called alopecia areata. It is also commonly called spot baldness, and it is believed to be an autoimmune disorder that causes the body's immune system to mistake hair follicles for foreign invaders, and then, attack them as such.
One of the most widely used and proven treatments is minoxidil (Rogaine and various generic products). It's available in liquid, foam, or shampoo options. Stronger forms of minoxidil are also available by prescription. Minoxidil may cause side effects like skin irritation or unwanted hair growth on skin near the scalp.
Make an appointment to see your doctor if: You suddenly develop a bald spot on your scalp. Your hair stylist tells you that your hair is thinning, or that you have small bald areas. You have lost your eyebrows or eyelashes, your beard is thinning, or you have noticeably less hair on your underarms or pubic area.
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.

This kind of hair loss often shows up as round bald patches. It can make you lose hair suddenly and seemingly out of the blue, according to NYU Langone Health. The condition happens when your body's immune system mistakenly attacks your hair follicles.
Yes, stress and hair loss can be related. Three types of hair loss can be associated with high stress levels: Telogen effluvium. In telogen effluvium (TEL-o-jun uh-FLOO-vee-um), significant stress pushes large numbers of hair follicles into a resting phase.
In many cases, bald patches regrow by themselves without treatment. In particular, if there are just one or two small bald patches then many doctors would advise that you simply leave it alone at first. If the hair loss is not too bad then there is a good chance that your hair will regrow after several months.
Alopecia areata frequently presents as the sudden onset of smooth, round, hairless patches on the scalp. The affected areas are usually skin-colored but may have a peach color. Occasionally, there are scattered short colored or white hairs within the hairless patch.
Sudden Loss of Patches of Hair
Bald spots may grow very slowly in one area or you may notice a patch or strip of hair loss that appears within just a day or two. In some cases, you may notice burning or stinging before sudden hair loss.
Asthma, hay fever, atopic dermatitis, thyroid disease, vitiligo, or Down syndrome: Research shows that people who have one of these diseases are more likely to get alopecia areata.
Alopecia areata, also known as spot baldness, is a condition in which hair is lost from some or all areas of the body. Often, it results in a few bald spots on the scalp, each about the size of a coin.
After hair stops shedding, the hair will slowly grow back. This can take 6 to 8 months for all the hair to grow back. The whole cycle takes about 12 months. This type of hair loss is called telogen effluvium.
Stress-related hair loss, also called telogen effluvium, typically starts 2 to 3 months after a stressful event and can last for up to 6 months.
Telogen effluvium hair loss — the type of hair loss linked to stress — typically affects your scalp and may appear as patchy hair loss. However, it can also cause you to shed more body hair or notice less hair on your body than you normally would.
Ways to Stop Alopecia Areata from Spreading or Worsening
Avoiding unnecessary hair or scalp trauma, reducing stress and analyzing your diet are all worthwhile endeavors when attempting to prevent alopecia areata from spreading.
If you're dealing with a temporary form of hair loss, your bald spot will likely grow back on its own. However, when bald spots or thinning are due to aging and genetics, that's not always the case. There are scientifically proven ingredients, such as minoxidil, that can help early hair loss.

The majority of androgenetic alopecia (or male pattern baldness) sufferers start noticing their hair loss in their mid to late twenties.
But some people with lupus develop round (discoid) lesions on the scalp. Because these discoid lesions scar your hair follicles, they do cause permanent hair loss. Lupus can also cause the scalp hair along your hairline to become fragile and break off easily, leaving you with a ragged appearance known as lupus hair.
After controlling for age, high cholesterol, smoking and other variables, they found that hypertension was “strongly associated” with male pattern baldness: those with a blood pressure reading above 120 over 80 had twice the risk of the others.
Alopecia areata is sometimes triggered by viral infections such as influenza that causes excess production of interferons (IFN). IFN- γ is one of the key factors that lead to the collapse of immune privilege.
For some, it may take as short as 8 weeks to see improvement with treatment. For others, the same treatment may not work. It is said that most cases of alopecia areata last for a few months to a year, following which normal hair growth resumes. However, there may be cases of permanent hair loss as well.
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.
