Try natural instincts - there's a red called spiced tea that comes out a vibrant darker red. Lasts longer on naturally light hair and washes out quicker on darker hair.

You could use Sunlit Dark Reddish Blonde by L'Oreal Feria. Or Ariana Grande uses Manic Panic Rock n' Roll.

buy a red hair colour such as loriel or garnia. you will need to buy a 28washes one or perminant dye so that it last for that long. i think you will see it everytime you wash it but most likely if you use a box dye you will only see it for the first few washes
