i think someone lied to my friend! she told her that if she washes her hair in cold water it will shine better than any product could make it. does anyone know if this is really true?
if you KNOW for a FACT that it works can you tell us why does cold water make your hair shiny?

i was just going to add that you don't have to wash your hair with wet water. you can just wash it regularly with warm/hot water and then do a final rinse at the end of the shower which will seal the cuticle. (I like doing this better so I'm not cold during my entire shower!) [ ConfusedX2's advice column | Ask ConfusedX2 A Question ]

To make your hair even shinier, you can use the cool air setting on your blow drier if you plan to blow dry it or use heat after washing your hair.

It works because your hair is made up of tiny scales, facing in the same direction. When you wash with warm water, the scales lift somewhat, making the shaft of the hair less smooth, and thus less reflective. When you rinse with cold water, the temperature makes the scales contract and lie flat, which makes your hair more reflective (shiny).
Here's a diagram of the hair shaft which shows what I mean:
