Alopecia areata is a condition that causes hair loss. Its exact cause is unknown, but factors such as genetics and the immune system are implicated. Hair begins to fall out, forming small or large bald patches. Hair follicles enter a resting phase, and the hair becomes thinner.
Androgenetic alopecia (common baldness) and telogen effluvium (seasonal hair loss or loss due to external factors) are the most frequent causes. Alopecia can present differently in men, women, and children, with symptoms such as increased hair shedding when combing or washing the hair.
Treatment options include topical medications, systemic medications, and, in more advanced cases, hair transplants. To prevent or manage alopecia, it is essential to maintain a balanced diet, avoid stress, and, when necessary, use nutritional supplements.
