I have very thick, ever so slightly wavy shoulder length hair which is probably around 50% grey by now. I've been dying it with semi-permanent home dye for years and over the past year or two it's been getting drier and drier. I get the ends trimmed every 3/4 months, use a colour protecting shampoo, conditioner and serum and only wash (and blow dry) it twice a week but it's getting crispier and frizzier. Has anyone else in their 40s with hair like this found a way of making it sleek and youthful looking again or am I asking for the holy grail? Going grey is not an option I'm afraid
