I have dark brown hair and lately it has been getting lighter, I like dark so I want to dye it black. But last month I bought one and my hair looks the same as it did before so I'm thinking the brand wasn't good. Also I do wash my hair often but I think it should last over a month.

Goldwell hair dye. It's a salon brand so it's top notch and it'll last a long time. You can get it at Beauty Brands or Sally's!1
