If I dye my hair darker, will all my natural highlights go away?
I naturally have dark brown hair and as my hair grows, the tips are turning lighter and I love my hair just the way it is, but just to fulfill my teenage experimental satisfaction, I want to dye my hair almost a nutmeg (darker) but I don’t know if all my natural highlights will go away, so I need to know if it will, thank you!
yeah, the dye covers everything up.
