Headache after washing

If you have a headache after washing your hair, you should pay attention to it. Migraine is the most likely cause of this symptom. We know that migraine is a relatively common disease in medicine. It is divided into primary migraine and secondary migraine. It has both genetic reasons and metabolic and endocrine reasons. In addition, mental factors and dietary reasons are also common factors.

What is a migraine

Migraine is the most common type of primary headache in clinical practice. Its main clinical manifestation is paroxysmal moderate to severe, throbbing headache. The headache is mostly unilateral and generally lasts for 4 to 72 hours. It may be accompanied by nausea and vomiting. Light, sound stimulation or daily activities can aggravate the headache. A quiet environment and rest can relieve the headache. Migraine is a common chronic neurovascular disease that usually begins in childhood and adolescence, reaches a peak incidence in young and middle-aged people, is more common in females, with a male-to-female ratio of about 1:2-3. The prevalence rate in the population is 5% to 10%, and often has a genetic background.

The cause of migraine is still unclear, but it may be related to the following factors:

Genetic factors

About 60% of migraine patients have a family history, and the risk of migraine in their relatives is 3 to 6 times that of the general population. No consistent Mendelian inheritance pattern has been found in familial migraine patients, reflecting the interaction between different penetrances and polygenic genetic characteristics and environmental factors. Familial hemiplegic migraine is a clear autosomal dominant inheritance with highly abnormal penetrance, which has been located at three disease gene loci: 19p13 (associated with mistranslation mutations in the voltage-gated P/Q calcium channel gene expressed in the brain), 1q21, and 1q31.

Endocrine and metabolic factors

The disease occurs more frequently in females than in males, usually during adolescence, with attacks more likely to occur during menstruation, and attacks decrease or stop during pregnancy or after menopause. This suggests that endocrine and metabolic factors are involved in the pathogenesis of migraine. In addition, metabolic abnormalities such as serotonin (5-HT), norepinephrine, substance P and arachidonic acid can also affect the occurrence of migraine.

Diet and psychological factors

Migraine attacks can be triggered by certain foods and drugs, including cheese containing tyramine, meat and pickled foods containing nitrite preservatives, chocolate containing phenylethylamine, food additives such as monosodium glutamate (MSG), red wine and wine, etc. Medications include oral contraceptives and vasodilators such as nitroglycerin. Other environmental and mental factors such as tension, overwork, emotional excitement, excessive or insufficient sleep, menstruation, and strong light can also trigger it.
