I just can’t afford to go to a salon to have this done. I’ve been using semi permanent for years but always find my hair is too dark especially around the hairline even with lighter tones! Was reading up on demi-permanent dye especially for my little greys :o) What i’m after is natural glossy hair on the day of my friend’s wedding (i’m bridesmaid) If I use demi permanent a week or 2 before will I achieve these results?? Any advice guys??
