Yesterday I used hairroot activator tonic on my roots (used it before, had no problems) and before I went to wash it off I used some hair oli to massage my sculp (used it before, but a long time ago).. then started to washed my hair as usual. When my hair started to dry I quicky realised something was wrong, my roots were sticky and really tough. The two propably didn't get along or the oil had gone bad or something like that. I washed them again several times with the shampoo, still they were the same. I google-d a bit tryed washing it with eggs, apple vingar and sea salt, even Fairy(the washing liquid)... I got the biggest part out.. but still the roots are far from clean... What else can I try?
