https://giggleostentatious.com/a3h6sfj0i?key=e09e0ed473b4afe6b5c424095bd3ea3b Causes

This disease causes sudden hair loss, which often begins as a round or oval, smooth balding patch that develops on the scalp or beard. However, hair loss can begin on any area of the body. Some people lose eyebrows, eyelashes, nostril hairs, or hair on their legs. Aside from hair loss, people with alopecia areata may also notice: Changes to their nails Itching, tingling, or a burning sensation where hair loss will soon begin or has already occurred Irritated eyes if eyelashes or eyebrows are lost The following alopecia areata photos show you the early signs, how this type of hair loss can progress, and some nail changes that can occur.

Round or oval, smooth bald patch on the scalp This patch is often the first sign of alopecia areata. Where you have hair loss, you’ll see no signs of irritation like swelling or discoloration

Hair loss may begin on the beard instead of the scalp. This hair loss may be patchy (A) or cause a well-defined bald spot (B)

Spotty hair loss (multiple patches) If the hair loss continues, more patches of hair loss appear. The patches can be large (A) or a mixture of sizes (B).

Widespread hair loss If the condition progresses, it can cause widespread hair loss, as shown here. Widespread hair loss is less common

 Loss of eyebrows When alopecia areata causes loss of eyebrows, people usually develop patchy hair loss on both eyebrows. Some people lose most or all their eyebrows, as did this patient.

 Loss of eyelashes Loss of eyelashes usually develops on both eyes, causing some eyelashes on both the upper and lower eyelids to fall out.

Band of hair loss Instead of developing one or more patches of hair loss, some people have a band or strip of bald skin on their scalp, known as ophiasis (oh-fee-ah-sis). This band usually appears at the back of the head and can extend to the temples (A).

Alopecia totalis Alopecia areata can progress, causing loss of all hair on the scalp (B). The medical name for complete loss of hair on the scalp is alopecia totalis (AT). This patient developed AT after experiencing widespread hair loss (A). AT is more common in children and young adults but can occur at any age 

Nail changes About 10% to 20% of people who have alopecia areata see changes to their nails. Tiny dents are the most common. You may also see red nails (A), ridges that run the length of the nails, nails that become so rough they feel like sandpaper, or brittle nails that split (B).

Alopecia universalis While rare, some people lose all the hair on their body. The medical name for this condition is alopecia universalis. This boy’s hair loss began with a single patch of hair loss on his scalp.

 Brittle and crumbling nails People who lose all the hair on their scalp and body (alopecia universalis) often develop brittle, crumbling nails like those shown here. This can be painful. 

Other signs that you may have alopecia areata include: Hair starts to regrow on its own where it fell out. Hair begins growing in a bald spot and starts falling out in another area. Hair loss occurs during a colder month of the year Cold may be a trigger for alopecia areata. In one study, researchers noticed that people diagnosed with alopecia areata most often had hair loss in November, followed by October and January. Patients had the fewest flare-ups during May and August. While anyone can develop alopecia areata,
