No, it does not.
There are a lot of different things that can cause migraines, from periods (hormonal changes), stress, smells (perhaps the reaction to a pleasant shampoo smell?), medications, and foods, to mention just a few. If you've had repeated migraines after washing your hair and going to bed with it wet, then it seems that could be a cause of your migraines. If washing your hair and going to bed with wet hair has only caused a migraine once or twice over a long period of time, then I would look elsewhere for the cause...

Many things cause migraines. Diet is one factor. Foods like cheese, chocolate, coffee, and other foods that contain caffeine can cause migraines. I am a migraine sufferer myself, and have found that playing video games, watching television or using the computer for long periods of time, can also trigger a migraine. Also, Migraine suffering can run in families. My father suffers from migraines and, consequently, I to suffer from them. Stress is another thing. If you've had a hectic day at work or school, or your feeling stressed, that can cause migraines. I hope I've been of some help.
