Patients with migraines should avoid washing their hair during an attack. Water that is too hot or too cold can stimulate the dilation or spasm of cerebral blood vessels, potentially worsening migraine symptoms. Therefore, it is advised not to wash hair during a migraine attack, though it is fine during remission periods. During a migraine attack, symptomatic oral pain relievers and medications to alleviate vascular spasms can be used for treatment. It is important to prevent migraines by avoiding staying up late and overexertion. Additionally, certain foods known to trigger migraines should be avoided, including foods containing nitrites such as leftovers, pickled vegetables, and other preserved foods which may contain nitrites. Foods like red wine and cheese can also trigger migraines and should be consumed with caution. (Medication should be used under the guidance of a doctor.)
