Alopecia areata

Alopecia areata is one Autoimmune disease, which is characterized by sudden, often circular hair loss on the scalp and sometimes on other parts of the body. In this disease, the immune system attacks Hair follicles on, leading to hair loss. It can affect people of any age, but often begins in childhood or early adulthood.


The main signs of alopecia areata are:

  • Round or oval bald spots : Most common on the scalp, but they can also appear in the beard area, eyebrows, or other parts of the body.
  • Tingling or pain in the affected areas just before hair loss.
  • Nail changes : Dents, grooves or a rough surface of the nails may occur.


The exact cause of alopecia areata is unknown, but genetic factors and environmental triggers are thought to play a role. An autoimmune disease, alopecia areata occurs when the immune system mistakenly recognizes hair follicles as foreign and attacks them, disrupting their growth and leading to hair loss.


There is currently no cure for alopecia areata, but there are treatments that can promote hair growth in some people. Treatment depends on the severity of the disease and the sufferer's preference:

  • Corticosteroids : These are anti-inflammatory medications that suppress the immune system and can be taken as injections, topical creams, or orally.
  • Minoxidil (Rogaine) : A topical medication applied to affected areas to promote hair growth.
  • Anthralin : A topical stimulant therapy that can stimulate hair growth.
  • DPCP (diphenylcyclopropenone) : A chemical applied to the scalp to produce an allergic reaction that can promote hair growth.


Alopecia areata varies greatly from person to person. Some people experience only a few episodes of hair loss with complete recovery, while others have repeated or persistent breakouts. In rare cases, the disease can progress to complete hairlessness ( Alopecia totalis) or loss of all body hair (Alopecia universalis) develop.

Dealing with the disease

In addition to medical treatment, emotional support is important for people with alopecia areata. Hair loss can lead to self-confidence problems and psychological stress. Counseling, support groups or therapy can be helpful for those affected and their families to deal with the emotional impact of the illness.

If you suspect alopecia areata, it is recommended to see a dermatologist for an accurate diagnosis and advice on treatment options.
