I'm a licensed hairstylist and unfortunately, the only way to highlight your hair is thru coloring/bleaching it. They do have on the market wild colors teenages use that are temporary and will wash out. They also have what we call a temp color, semi-color and demi-color but none of these will lighten your hair, they'll only darken what you already have. If you want to just accentuate your grey, I suggest using a temporary RINSE. This is something you use after you shampoo your hair and you apply it to your wet hair then BLOT and style as normal. However, this WILL wash out on your next shampoo. I suggest you go to your local beauty supply place and tell them to suggest for you a temporary RINSE that would accentuate your grey but there is nothing temporary that will color/hide your grey; you would have to look at a permanent color for that. Hope this helps, good luck!
