Is there any difference between Salon grade dye and box dye? (I am guessing there is)
someone said to me today that the way to cover my stubborn grey hair is to use salon grade dye but I don’t know where to start. Does anyone do this? Or could you recommend a range/ brand to try and tell me what I need? (Eg colour plus developer?
box dye literally just washes out of my hair on one or two washes now, it’s so frustrating and expensive.
