I dyed my hair red really red but everyone two to three weeks it starts showing like brown or orange how do I stop that from happening :confused:

Unfortunately that's why its called temporary and not permanent color. Just remember that if you color your hair too much it can also fall out in time

Red dye is notorious for fading; there's nothing you can do to prevent it, but you can prolong the color by using high-quality products made for color-treated hair. Look for shampoo, conditioner, and a UV protector. You will also probably get better results if you color your hair in a salon rather than at home. I sometimes go as long as eight weeks between colors.
