The current mens hair trends are masculine and sophisticated (and will look cool in photos forever). If you’re starting with the right cut, your hair still looks great without styling. So wearing hair messy still gives you cool mens hair.
The modern take on short sides – long on top is brilliant worn slicked back or up but that’s not all it can do. For the weekend, just let go (also good to have a day or two to really wash out any product build-up, or try this Neutrogena Anti-Residue Shampoo).
Hair will look great worn slightly messy is an updated version of bed head that still looks distinguished and cool.
