A good haircut, some tended-to scruff, and hydrated skin can make a huge difference in how a man looks. And if you ignore all three, well, you won't look like a DGAF rebel as much as an intensely hungover, decade-older version of yourself. In order to motivate you to visit the barber regularly, change up your grooming game once in a while, and use more than a dried out bar of soap in the shower, we're bringing you a recap of the best grooming moves of the week, every single Sunday. Up this week: three pop-stars with excellent haircuts, a model with enviable skin, and a guy that looks a little bit like Ernest Hemingway, down to the turtleneck. Enjoy.

Zayn Malik went full Bladerunner on us this week with a new, highly textured asymmetrical fade. While we respect his grooming bravery, we're partial to the wavy, slicked back cut he was rocking earlier in the week. Call us traditional.

Some haircuts take a little bit of breaking in. Maybe you're experimenting with the right mix of products, or tinkering with how often to get it cleaned up. This must be what's happening with the Weeknd's hair, because it's only looking better as the weekends go on.

Summer is coming and Luka Sabbat—in shorts and an easy T-shirt at the H&M runway show in Paris—was proof that all you need to look great is some body lotion, some confidence, and some well-placed tattoos.

One look at Zachary Quinto's intensely thick eyebrows and you knew the guy had the potential to grow a serious beard. While there's still some winter left, he's decided to show us what he's made of in that department. The verdict: He's made of a lot.
