We all watched “The Joy of Painting with Bob Ross” in 80s and 90s. His painting skill was like magic for us. Do you know his hair was straight and why he kept his curly hair even after he was famous? After he was out of US Air Force, he decided travel and have a career as a painter. His hair was naturally straight but he chose to get a perm so he could save money on haircuts when touring the US penniless in his mobile home. Bob actually hated his curly hair but kept it as it was iconic. All in all it is a really big success story. Thank you, Bob Ross. We were all happy little trees thanks to you.
