Alopecia areata afflicts millions of people around the world, but it is often not diagnosed because it initially appears as simple bald spots on the scalp. For this reason, it is often referred to as spot baldness, and it resembles the natural loss of hair as people age.

hair loss related condition in which hair typically fall out in round patches. There are different types of alopecia, for example, male and female pattern , and alopecia areata.

It can develop into two different forms of the disease if left untreated:
- Alopecia totalis (AT): In this form the entire scalp becomes bald.
- Alopecia universalis (AU): In this condition, all the hair on your entire body is lost.

In alopecia areata, the immune system mistakes healthy parts of its own body for foreign, damaging materials, and attacks the hair . Hair follicles are cavities from where the hair grows. When the immune system attacks them, they reduce in size and then gradually stop producing new hair. This is what leads to hair loss. The precise cause of the condition is still unknown because scientists are unable to figure out why the immune system attacks the hair follicles. However, it’s been discovered that it generally occurs in people with a family history of autoimmune diseases, like arthritis, lupus, multiple sclerosis, type 1 diabetes, etc. This is also the reason why some scientists believe plays a role in alopecia areata.
- Environmental factors: These also play a big role in triggering alopecia areata in people who are prone to the disease.
- Thyroid disorders: Alopecia areata is often associated with thyroid because the balance in the body is key to stimulating or shutting off hair follicles and thyroid disorders throw your hormonal balance out the window! Since the condition can get worse in no time, it is very important to treat it before it gets out of hand.
