How do you dye/color gray hair?

My mom has jet black hair and she very noticeable grays random all over her head. She's highlighted her hair brown but that doesn't seem to cover them up and the salon is getting expensive. Is there a drugstore brand or even Sally's product that works for you? I'd like to dye her hair dark brown and add some highlights to it.How do you dye/color gray hair?
i have the same problem,being a brunette,my greys really show.What i do isbuy a semi permanat (i.e chestnut -OR a darker shade ...What works 4 me is Mahogny --because it has red in it) That seems 2 work, covering the horrible,stringy,thick ,grey hairs.....Go l lHow do you dye/color gray hair?
Grays are very hard to get rid of.But i would suggest a DARK BROWN, with some lighter streaks,as myself have the same problem as mum,im now proud as punch.You can buy your own kit at any outlet or supper market,it has the colour in it along with a brush to do your own highlights where ever you want and its fun.Tell mum be proud of her gray hair as i call them my streaks of wisdom.It cost under 30 dollars,just have fun wiyh it girls.god bless and good luck.Your friend ANNE.....
Dye her whole head a color that is made for covering greys, they have brands specifically for that because the hair itself is harder to permiate. Then do the highlights.
jus dye the whole head with wat ever color she wants
i use revlon. its te cheapest, but works really well. for my hair atleast. just use jet black dye...
get pink
