I will get down to earth, and not beat around the bushes - Ladies, this product is the best there is to purchase if you want a glistening, great silvery shine to your hair. I was in my 50's when I first used this brand, and now I am in my 80's and STILL using it. The silver tones that highlight my already silver hair are outstanding. Wherever I am, shopping, social gatherings, marketing, I have had women tell me they "love" my hair and what am I using! For a product that I have been using for more than thirty years, that is truly a wonderous thing. I'll keep using it until I leave this planet, and hopefully where I end up, there will be a place where I can continue to buy Schwarzkoff Osis Sparkler!
