I remember reading on the webs that bull semen was the new thing to make your hair healthy looking and shiny I was wondering if that could actually work?
Basically, anything that has a little gloss to it can coat your hair and make it look shiny. But it has to be left in your hair to work and it certainly won't work as well as an ingredient like silicone. Considering the potential issues with sourcing, I think I'd stick to a good shine spray.
