Q: Can you sleep with temporary hair color? I mean, go to bed a couple of hours after getting your hair dyed?
A: By its nature, temporary color is made to rest on the outside of the hair shaft and therefore can be subject to being rubbed off via friction against bedding fibers (running/bleeding if you perspire).
You can certainly sleep in temporary color, but unless you have dark bedding that won't show color stains, you might want to invest in a sleeping cap (made preferably with a natural silk or satin fiber/weave) to keep the color from staining your bedding.
Furthermore, make sure that your hair is completely dry before bed. Any dampness in the temporary-colored hair will surely lead to color bleed.
