Alopecia areata is an autoimmune condition that causes sudden hair loss in patches. It can affect both men and women of all ages, and there is no cure. However, there are treatments that can help to slow or prevent the hair loss and sometimes promote hair regrowth.
What Causes Alopecia Areata?
The exact cause of alopecia areata is unknown, but it is thought to be an autoimmune condition. This means that the body’s immune system attacks its own hair follicles, causing them to stop producing hair.
There are several factors that may trigger the development of alopecia areata, including:
- Genetics: Alopecia areata is more common in people who have a family history of the condition.
- Stress: Stress can trigger alopecia areata in some people.
- Illness: Certain illnesses, such as thyroid disease and lupus, can increase the risk of developing alopecia areata.
- Medications: Some medications, such as chemotherapy drugs, can cause hair loss as a side effect.
Symptoms of Alopecia Areata
The most common symptom of alopecia areata is sudden hair loss in patches. The patches of hair loss are usually round or oval, and they can vary in size from small to large. Alopecia areata can affect the scalp, eyebrows, eyelashes, and other areas of the body where hair grows.
In some cases, alopecia areata can progress to total hair loss (alopecia totalis) or complete hair loss from the entire body (alopecia universalis).
Treatment Options for Alopecia Areata
There is no cure for alopecia areata, but there are treatments that can help to slow or prevent the hair loss and sometimes promote hair regrowth.
Medications
- Minoxidil: Minoxidil is a topical medication that is applied to the scalp. It is available over-the-counter and by prescription. Minoxidil can help to slow or stop hair loss and promote hair regrowth in some people.
- Corticosteroids: Corticosteroids are a type of medication that reduces inflammation. They can be applied to the scalp as a topical medication, or they can be taken orally. Corticosteroids can help to slow or stop hair loss in some people.
- Immunosuppressants: Immunosuppressants are a type of medication that suppresses the immune system. They can be taken orally or given as an injection. Immunosuppressants can be used to treat severe cases of alopecia areata.
Light Therapy
Light therapy involves exposing the scalp to ultraviolet light. Ultraviolet light can help to suppress the immune system and promote hair regrowth. Light therapy is typically performed in a dermatologist’s office.
Other Treatments
- Platelet-rich plasma (PRP) therapy: PRP therapy involves injecting the scalp with a concentration of platelets from the person’s own blood. Platelets contain growth factors that may promote hair growth.
- Scalp massage: Scalp massage may help to improve blood circulation to the scalp and promote hair growth.
- Stress management: Stress can trigger alopecia areata, so it is important to manage stress levels. There are many different stress management techniques that can be helpful, such as yoga, meditation, and exercise.
Coping with Alopecia Areata
Alopecia areata can be a challenging condition to cope with. It can lead to feelings of self-consciousness, anxiety, and depression. However, there are things that you can do to cope with alopecia areata, such as:
