The occurrence of itchy alopecia areata scalp is primarily related to the use of certain medications. Frequent use of drugs to treat alopecia areata can lead to allergic reactions, which may also cause scalp itching. Additionally, in the early stages of alopecia areata recovery, hair growth requires a significant supply of nutrients, and rapid local blood circulation can also lead to localized scalp itching. The itchy scalp associated with alopecia areata can also be related to irregular lifestyle, long-term mental tension, frequent staying up late, and deficiencies in vitamins and trace elements, which can lead to endocrine disorders. The itching associated with alopecia areata might also result from not maintaining cleanliness and hygiene of the scalp, using shampoos or conditioners with strong irritants, frequent exposure to excessive ultraviolet rays, and using excessively hot water when washing hair.
