I just needed to state my appreciation for this ace product which I've been road-testing for the last six months and will stick to from now on. I'm 46 and have been turning steadily grey over the last six years - in some places am actually quite white. Luckily I still have a full head of hair, but have always needed to keep it very short to avoid the wiry & tired-looking hair which I would otherwise be prone to. Have been using quite a few silver shampoos over the last couple of years as the standard shampoos just don't do it anymore, which struggle to wash out the yellow & brassy tones and give my hair some proper healthy shine. Problem I've always found is that the specialist silver shampoos are either loaded with moisturizing agents, leaving my hair looking limp and floppy, or are overdosed on optical brighteners, which do the trick for a day or two but don't last the course. This Schwarzkopf product kicks both these issues into touch - leaves my hair soft and manageable and keeps the greys and whites looking fresh and shiny. It's expensive if brought from the salon (around £15) but it can be had online (as here) for under a tenner. I shampoo once a week, using it sparingly and washing twice, and it does the job beautifully, cheers Schwarzkopf!
