Alopecia areata is typically defined by ring-shaped bald patches on the scalp, and its symptoms are all characterized by this indicator. If the disease continues to worsen or spreads, it has the potential to evolve into alopecia totalis or universalis; thus, if you see one or more bald patches on your body in areas where hair would normally grow, you should consult a dermatologist to get an official diagnosis. 

Alopecia Areata Totalis 

Due to the fact that Alopecia Areata Totalis is defined by the full loss of hair on the scalp, medical professionals are hesitant to diagnose patients with this condition. Although there is no known treatment for this problem at the present time, it is known that hair may regenerate in patients even after a number of years have passed. This kind of hair loss is distinct from a disorder known as telogen effluvium, which causes temporary hair loss and is generally brought on by stress. Twenty percent of all persons who have this type of hair loss also have a family history of alopecia. 

Alopecia Areata Universalis 

This disorder is quite similar to alopecia areata totalis, however rather than causing patchy hair loss all over the body, it causes complete hair loss on the scalp. This includes your eyebrows, eyelashes, arms, legs, private region, the inside of your nose, and any other place on your body where hair may grow. It is believed that an autoimmune condition is the cause of this particular subtype of alopecia. 

Diffuse Alopecia Areata 

Diffuse alopecia areata, also known as alopecia areata incognito or DAA, is a form of alopecia that does not present itself as bald spots the size of coins. This form of the condition is more common in younger women. It manifests itself as sudden hair loss that takes place on the scalp. This disease, like Totalis and Universalis, may either recur or be a one-time occurrence for the affected individual. One third of all women diagnosed with DAA have instances of spontaneous hair regrowth and make a full recovery even without receiving therapy. 

Because rapid hair loss like this may be caused by a variety of factors, including stress both physical and emotional, medication, radiation, a deficiency in biotin, and even some illnesses, it is essential to monitor both your physical and mental health in order to maintain healthy hair. 

Alopecia Areata Ophiasis 

This particular kind of alopecia is characterized by a pattern of hair loss that resembles a snake. The word “ophiasis” originates from Greek and means “snake.” The presence of a T cell-mediated (immune response that does not need the presence of any antibodies) autoimmune illness, which manifests itself as a hairband-like breadth of bald patches on the scalp, is what gives this case its singularity. The temporal lobe, occipital lobe, and parietal region of the head are the areas of the scalp that are most often affected by ophiasis, and the disease may cause hair regrowth to be more cyclical than it is in other cases. 

Cicatricial Alopecia Areata

Cicatricial alopecia is a kind of hair loss that is caused by a reaction from the immune system to the developing hair follicles. Scar tissue replaces the hair follicles, making it very difficult for new hair to grow through the scalp. This kind of alopecia areata is quite distinct from the other varieties. Because of this, the scalp may become scaly, red, or even bald as a direct consequence of the condition. This form of alopecia may be helped by reducing the inflammation in your body, which can be accomplished by consuming more foods that are anti-inflammatory.
