The big lesson for today is... patience, gentlemen. Patience!
The biggest mistake men make washing their hair is that once they put the shampoo or conditioner in their hair, they rinse it right away. NO! You have to be patient! Let the product sink in and do it's magic. It is not a miracle worker, it needs a minute or two to soak into the hair and scalp. SIng your favorite tune for a minute, or use your watch and time it (or ideally wash you body while the shampoo gets to work). Then, after 2 minutes you can rinse it out and have that Bueno Hair we all want and deserve.
