Test hair dye Olia medium brown

I got this product to test. This just worked out because I just wanted to dye my hair again! I got the color medium brown. The product actually doesn't smell bad, although I think it often is the case with other hair dyes. Also a nice color afterwards. However, after that, my hair was very oily even though I had washed everything out thoroughly. So I'll give it a 9/10 for the rest. Only the greasy one was a minus
