Leave the dye to sit for about 15 to 30 minutes, and then rinse out and style as usual. No matter which type of semi-permanent hair dye you use, make sure to carefully follow all directions.
Because there's no oxidation process involved in using semi-permanent dyes, the recommended amount of time is 20 to 30 minutes. But some people who want brighter or darker hair color need to leave hair dye in for longer. And it's okay to leave it in for longer because semi-permanent hair dye won't dry out your hair.
So leaving it in longer than intended won't harm it any. It can possibly make the color more vibrant or a bit darker depending on the shade and tone of your hair.

Salons wash hair after coloring because they need to prepare your hair for the next treatment, which is important if you are planning a straightening or curling treatment directly after your hair has been dyed.
“I generally tell my clients to wait 48 hours before they wash their hair,” VanDyke says. During the first 48 hours after a color service, the pigments of the salon color are still settling—meaning if you shampoo your hair too soon after an appointment, it can cause your hue to fade quicker.
