So, what I have here is I have three examples of gray, how gray hair really grows on the head. What tends to happen is usually people start out here and this is more twenty-five percent. So what happens is they have a little bit of their natural color still in the cuticle but they also have the gray which is also the scientific name for gray would be canities and what happens is it starts to grow in as you get older. Also hormones can effect gray coverage, I mean not gray coverage, I'm sorry, can effect how gray starts to appear in your hair. So, what we have is we have twenty-five percent, we have fifty percent and then down here is seventy five. And this is really seventy five to one hundred percent gray. What starts to happen with guests as you get gray is it becomes more of a maintenance situation of you getting your hair colored because a lot of women, even if they even see a little bit of gray, they're like, oh, I need to have my base covered. They don't even want to see it so it starts to get, it starts to be a cost issue. So a lot of women, consumers, choose to go to the store and buy box color and apply it. But what starts to happen is because as consumers you all don't know the chemistry of color, it starts to take on different tones in your hair.
