You have red hair and it keeps fading quickly you have used a semi-permanent dye then a permanent one over it but it still fades any ideas how to stop it from fading?

Artificial red colored hair is one of THE MOST difficult colors to maintain. It usually needs to be touched-up weekly or so, with semi permanent colors in order to maintain its vibrancy. Purchasing a color protective shampoo for reds will also help with the fading.
