Startup Idea : Make shampoo easier to wash out!

Sodium Lauryl Sulfate is one of the most effective hair cleansers, especially for someone for me with fine, straight hair. Without using a product with this cleansing ingredient, my hair looks greasy and weighed down. The problem with SLES is that it can be hard to wash out. I waste too much water trying to get it out of my hair. I wish there was a personal care product that I could put in my hair after I shampoo to make the shampoo rinse out faster and easier.
