What Alopecia Areata Looks Like
Finding a smooth, round patch where hair used to be can be unsettling. For many people, that is how alopecia areata first appears. It usually causes sudden, nonscarring patches of hair loss, most often starting as one or more round or oval spots on the scalp. It can also affect the eyebrows, eyelashes, beard, and other areas of the body.
In rare cases, hair loss spreads to the entire scalp, called alopecia totalis, or to the entire body, called alopecia universalis. Most people, however, experience patchy loss.
What Causes It
In alopecia areata, the body’s immune system mistakenly attacks hair follicles. Researchers do not yet fully understand why this happens. The encouraging part is that the follicles are not destroyed. They keep the ability to grow hair again, which is why hair loss from alopecia areata is usually not permanent.
The condition sometimes runs in families, and it can occur alongside other immune-related conditions such as vitiligo and thyroid disease. Many people wonder whether stress caused their hair loss. That connection is still debated, and alopecia areata is not caused by “nerves” or by anything a person did wrong.
How a Dermatology Provider Can Help
Not every patch of hair loss is alopecia areata. Thinning, shedding, and bald spots can have many causes, and the right treatment depends on the right diagnosis. A dermatology provider will look closely at your scalp and hair, ask about your health history, and help sort out what is going on.
Before your appointment, note when you first saw the patch and whether it has grown or new spots have appeared. Bring a list of recent illnesses, new medications, or major life changes, too. Photos taken over a few weeks can be useful, since slow changes are hard to judge in the mirror.
There is no cure for alopecia areata, but treatment can often help hair regrow during an episode. Depending on how much hair has been lost, options your provider may discuss include:
- Cortisone injected just beneath the skin in affected patches
- Topical cortisone applied to the skin
- Other topical medicines that may support regrowth
- A short course of oral medication when hair loss is rapid or widespread
- Custom wigs or hairpieces while waiting for hair to return
Your provider will explain the benefits and possible side effects of each option and help you choose a plan that fits. When hair does regrow, it may come in lighter in color at first. Future episodes cannot be reliably prevented, so it helps to have a provider you can return to if new patches appear.
Taking Care of Yourself Along the Way
Hair loss can affect how you feel about yourself, and that is a real part of living with this condition. Some people find it helps to talk openly with family or friends, connect with others who have alopecia areata, or try hairstyles, hats, or scarves that make daily life easier. Having a plan with your provider can make the waiting feel more manageable.
It is also wise to be gentle with your hair and scalp. Avoid harsh styling or chemical treatments on affected areas, and protect bare patches from the sun. Sun protection still matters in fall and winter here in Idaho.
