I have used plain shampoo forever, I dont put crap in my hair.
However, I may start using conditioner. I may be around a bit more, and possibly try a tiny bit of modelling. So I think I may want a bit more shine.
I also find it funny, I think more of the straight guys are actually using conditioner. I know I dont use conditioner, and I dont think the other 2 gay people on here (besides Mac Mogul) use conditioner.
