How can you get rid of a semi perminant colour from your hair?

Ok the thing is, i have blonde hair and its kinda boring me now. So i was gonna put some pink in it. Like that stargazer or beond the zone colour. But ive notcied it fades really quickly, but i really want it for a bit. Is there anyway i can get rid of it once its gone from the orignal colour to the faded gross one.

like any shampoos? or products?

How can you get rid of a semi perminant colour from your hair?

Semi-permanent

This product adds color without changing natural color dramatically. The hair color contains tiny color molecules that enter the hair's cuticle, or outer layer, and go into your hair's cortex. They don't interact with your natural pigments. And since the molecules are small, they eventually exit the hair shaft after several shampoos, leaving the hair as it was before treatment. This level generally lasts for 6 to 12 shampoos, covers up to 50 percent gray, enhances your natural color and leaves no roots. This hair coloring won't lighten your hair color because it contains no ammonia or peroxide. (Both semi- and demi-permanent colors can become permanent on permed or already-colored hair!)

However, the color you're describing sounds like a stain which does just that stain. Go to a professional if you don't want be left with a faded pink result that wont wash out.
