There is a Malasaña look. Not uniform, but recognisable. These are the neighbourhoods visual codes right now.

Hair: structure without discipline

Cuts with clear shape but natural finish. No heavy hold. Texture over neatness. Lots of mid fade and skinfade, subtle mullets, textured fringes.

Beard: not too big

The huge lumbersexual beard stayed in 2018. Now it is finer: medium well-defined beard or stubble. Clean without looking just-shaved.
