In some cases, triggered by anxiety attacks or acute stressful conditions.

Alopecia areata can occur at higher rate with other autoimmune conditions such as: Thyroid diseases, Pernicious anaemia, Atopic dermatitis, or Vitiligo.

• Round or oval patches of hair loss: These patches can appear anywhere on the body, including the scalp, eyebrows, eyelashes, beard, and even other parts of the body.
