There are many causes for alopecia areata, most of which are related to diet and lifestyle habits. For example, frequently being picky about food, having an unbalanced diet, or consuming spicy and heavily flavored foods can trigger it. Long-term staying up late, anxiety, stress, and being in a bad mood can also cause it. Once alopecia areata occurs, try to avoid dyeing or perming your hair, as these chemical materials can potentially irritate the scalp and exacerbate the condition. It is recommended to seek proper treatment immediately after discovery, otherwise the condition might worsen, leading to complete hair loss or loss of eyebrows. Regular consumption of beans and maintaining a healthy diet and sleep schedule are also advised.
