I only wash my hair once a week to save the color but my red hair color still fades a lot, any advice?

I am sorry to say this, but red hair often fades the first time it's shampooed. You can save the color fading by using a color refresher at least once a week or a color shampoo. If you are only shampooing once a week your hair will only look dull and dry. Hair should be rinsed and conditioned everyday. It must be clean to have shine. If you don't want to shampoo everyday, simply rinse to remove the residue. Healthy shiny hair is clean.7. My hair always seems dull. Can I get shine without using a conditioner? Conditioners make my hair limp.Chemically treated hair is dull when you don't use treatments and conditioners. These are a must for healthy hair. Use an oil free treatment or just put it on the ends.  more
