Yes! To warm weather. I always thought of April as the time to shave off any winter hair to prevent any unwanted bad tan lines.
I let mine grow for a few weeks but just few days ago, I shaved it off again and had unspeakable tan lines. I don't know why that would happen after just a few weeks growth. I am an outdoor guy but having a white scalp just isn't a good look for me. It will tan up pretty soon but it's still kinda cool outside so I can't do much about it at this point.
Great news for you northerners. Here in South Louisiana, it is basically bald head weather year round. We do have the occasional cold spells in the winter, but it usually only lasts a few days at a time and then we get a few days in the 60's and 70's mixed in.
