In the 1970s when hairstyles were changing and the process style was fading, men were habituated to wearing their hair long. So, in the 80s, they let their hair grow at the back of the head while keeping them shorter at the top. This was the first form of the shag hairstyle worn by men which was soon adapted into various styles.

The 70s was an era of the youth, the end of the Vietnam War added in making it the turning point for them. Platform shoes, disco dancing and the Beegees; this new found youth was perhaps the reason for the emergence of this carefree, youthful and messy hairstyle- the Shag hairstyle.
