What is the healthiest brand of semi permanent hair color that will cover gray?

• My grandmother is 63 but honestly looks about 20 years younger. Her hair is very fine and about 90% gray. She has been having it professionally colored with permanent hair color for years and it's in very bad condition from the chemicals. She has tons of broken off hairs that stick out all over her scalp. Her hairdresser told her she has aging hair and that's why her hair is so damaged (the chemicals he's putting on it aren't helping). He recently convinced her to have her hair cut shorter (a couple of inches above her shoulders), telling her it would get rid of all the damage. That didn't happen. She used to have longer damaged hair and now she has shorter damaged hair. She's very unhappy and frustrated with her hair situation and I have convinced her to learn to color her own hair (she's never done it herself before) using a semi permanent color (I've never died my own hair either so I'm trying to educate myself so I can help her). I've been doing a lot of research and apparently semi permanent hair color doesn't adequately cover gray hair. Also, I found a lot of complaints that many colors have a reddish tinge. My grandmother tried red hair in the past, but it just doesn't go with her skin tone and looked really awful. She wants to find a color that will be close to her pre-gray natural color, which was dark blonde - not the darkest dark blonde shade but definitely not yellow or platinum blonde and it has to be a shade that does not have red in it and that will not have a reddish tinge when it fades. I have three questions: 1. What would be the best and least damaging brand of semi permanent hair color to use? I'm considering Clairol Natural Instincts. 2. How can my grandmother grow her hair out yet cover the gray roots without an obvious line between the old permenent color and the new semi permanent color? Should she color just the roots or pull the color through to the ends? If she pulls it through, won't that make the hair colored with permanent color darker that the roots which she will be coloring with semi permanent color? 3. Will those short broken-off hairs grow out if she switches to semi-permanent hair color? If this turns out to be a disaster, my grandmother will never want to do her own haircolor again. Thanks for any advice.
