I don't, and never have, conditioned my hair. I use tresseme shampoo, the black bottle with gold textbox. I shampoo once every day in the morning or early afternoon.
People routinely tell me I have very soft hair. Even though my hair is thin (not balding, I mean literally thin, so I can't style it really) I am blessed. Having soft hair that girls like touching is very nice.
Sadly I don't interact with women except my friends' wives so I don't get to take advantage of my natural blessing.
