I was a light brown and during the last summer I dyed my hair red I had to dye it out so I went a dark brown my hair is now a really dark brown! I want my light brown back! I can't go to the hairdresser as I suffer from a syndrome were I can't go out in public and socials a lot.. so I need like shampoos or stuff I can get in the house I need help!!

I think your hair is not used to dye and what happens is that your hair fades and isn't moisturized because all of the stuff blocking air and air keeps color so I suggest wash your hair like 3 a week. GUESSING!
