Any advice please! I’m in my 40s ,have naturally brown hair that I’ve been putting blonde highlights in since teens ..now ,mainly grey coming through (esp at the front ) ..I’m currently a mixture of highlights /grey and supermarket “root cover up”as the grey just comes through so quickly .Is an overall tint the answer now ?How to avoid a blocky look? Hairdresser suggested continue highlights and let the grey come through ,but I’m just not ready for that 🤔Can’t afford to get highlights every month tho’( time or financially ) I get ash blonde highlights .Thank you!
