On top, the hair was kept relatively long (around 3 to 4 inches). Kohli styled this into a textured quiff that was brushed up and slightly back. Unlike a pompadour, which is rounded and smooth, the 2016 Kohli look had texture and movement. It looked rugged, not overly "gelled."
To understand the hairstyle, you have to understand the man in 2016. This was the year Kohli was in the form of his life. Whether it was the IPL, the T20 World Cup, or Test cricket, he was scoring centuries for fun.
The core of the hairstyle was the undercut. The sides and back were clipped short (usually a number 2 or 3 guard), creating a stark contrast with the longer hair on top. This created a "disconnect" that emphasized the top section, making the style look voluminous and sharp.
