Lawn care during a drought

Out here in California we are suffering from a drought. Many people have yellow lawns from not watering and I know it's killing them. Not sure if any out here in California are aware of this product. It's basically a die that you apply to your lawn that turns it green and lush looking. I've seen it in action firsthand and was pretty amazed by its results. Places like Arizona that are commonly water short use this stuff all the time. You can buy the product or so or there are even companies that come out and will apply it for you. I'm not sure of the exact product my friend used but the before and after pictures were very similar to the one I am posting
