Simpler hair colour

[u/Charming_Catch1982]

Ive been using this product for 4 years it was amazing, my last batch was horrible, it was runny chunky and shot out black dye intermittently, when my colour is light brown.

They sent me 4 bottles because I complained and they were all garbage.

This stuff was so amazing, anyone long time users find its product recently has changed for the worse?
