Schwarzkopf Essence Ultime Diamond Color & Radiance Shampoo with Pearl Essence, 13.5 fl oz bottle - it's a big bottle! The color protect formula touts anti-fading and I thought it did make a difference so my blonde did not revert to brassy or dull. Most noticeable was the natural looking shine and my hair felt thicker and fuller. The ad says it has 'pearl essence' in it - not sure what that does... Cost about $10 in Walmart, but goes on sale for $8.
