Is there a shampoo that will make my hair thicker?

I am a guy my hair is about 5-6 inches long all around, trying to grow it out a little more. My problem is that my hair is thin and just mats down most of the time. I use some shampoo, but I am not sure of the specifics, and no conditioner.





Does that Mane and Tail make it thicker? Is it all about conditioner?Is there a shampoo that will make my hair thicker?
