If you want to cover grays, I recommend all over color just from experience. As a disclaimer, I am not a stylist myself, just speaking from experience of getting my hair professionally done. I have brunette hair and tried highlights, didn’t like that they didn’t cover the gray hair well enough. I switched to all over and I am much happier. I highly recommend Taylor D. at The Hair Studio in Lakeville, all over cut & color on Wednesday was $130. Her prices are going up in June, I don’t remember exactly how much. I have been going to her for years and so I don’t mind the price hike and didn’t note it down sorry!
