I have blonde extensions and I want to dye them Brown.. I bought blonde because they only had black and blonde, so I figured it would be easier to just dye them brown. Well, I have dyed them about three times but my problem is that only some of the hair is taking color. I have a bunch of blonde strands still, and it's making my extensions look silver. I have used protein filler and it doesn't seem to make a difference. What do uou suggest doing to get the blonde to dye brown as well?
