* Alcohol Evaporates Quickly: Alcohol is volatile, meaning it evaporates readily at room temperature. Any alcohol on the surface of your hair will likely evaporate within a short amount of time.
* Absorption is Minimal: While hair can absorb some substances, the amount of alcohol that would be absorbed from, say, a hairspray, and then remain detectable, is minimal.
* Shampoo Action: Shampoos primarily clean the surface of the hair and scalp. They remove dirt, oil, and product buildup. They aren't designed to extract substances that have been absorbed into the hair shaft.
In summary: The alcohol will evaporate on its own quickly, and no shampoo can remove alcohol from your hair.
If you are still concerned about alcohol in your hair, you can wash your hair with regular shampoo. This will help to remove any dirt, oil, and product buildup that may be trapping the alcohol.
