I'm only in my mid-twenties, but my # of gray hairs has been getting progressively worse lately ?? I've put off coloring my hair because it doesn't bother me that much on a normal day, but I definitely want to do something about it for my wedding day. Can I just dye it for the wedding, or will I have to upkeep it after? Is it worth it to dye everything or should I try one of those root touch-up products (pretty much all of my grays are short hairs by the root)? Either way, I definitely will trial it beforehand which is why I'm asking now
