Ok so I have been lead grey/ silver for ever. Back of my head is a bit more salt and pepper. Just fed up with colour, it makes me look like an old mum. Is there such a thing as whole head coverage for greys. Cant afford to spend at hairdressers every 5/6 weeks. Don’t want to go dark just a bit blonde but not look like I smoke 60 a day. Is there such a product?…
