Can patients with alopecia areata use stimulating shampoos?
Generally, patients with alopecia areata are not advised to use stimulating shampoos, as this may exacerbate their condition. Detailed analysis is as follows:

Alopecia areata is primarily caused by excessive mental stress, autoimmune factors, genetic predisposition, and other factors leading to sudden localized patchy hair loss. The scalp of patients with alopecia areata is usually sensitive, and using stimulating shampoos may further irritate the scalp, worsen hair loss, and even trigger scalp inflammation and other problems. Therefore, to avoid unnecessary irritation and damage to the scalp, patients with alopecia areata should尽量 (avoid) using stimulating shampoos.
Patients with alopecia areata can choose to use neutral or weakly alkaline shampoos, as these are usually milder and less irritating to the scalp. If necessary, under a doctor's guidance, patients may use specialized hair care products that have anti-inflammatory and scalp-soothing properties.
In daily life, patients should maintain healthy lifestyle habits and avoid consuming spicy or irritating foods, such as chili peppers and Sichuan peppercorns, which can help reduce the burden on the scalp and promote recovery from the condition.
