Apparently if you have oily hair, you’re supposed to rinse your shampoo out with cool water, whereas, if you have dry hair, you should rinse with hot water. I don’t know why you’d be shampooing your hair if it were not oily; I guess some people just feel the need to use up shampoo reserves.
There’s still one more day of Shampoo Week left to go. See you tomorrow!
