As a teen, and even now I am plagued with world class "cowlicks." As a youngster I used Butch Wax to solve the problem but I haven't seen it for years. Nowadays I don't worry about the cowlicks because I don't care how I look!I could carefully comb, brush, and dress my hair so it was just like I want it.
One gust of wind ... McCarter! I fought it all my life.
When I was a youngster: Brylcreme-head (slicked down and shiny). Now I just shave it close or wear a hat.
