#4 - Alistair Overeem
Alistair Overeem is a former heavyweight champion with various MMA promotions, including Strikeforce and K-1. The former kickboxing champ enjoyed quite a successful run in the UFC since making his debut in 2011. However, Overeem is not just a fighter with one of the worst haircuts in UFC history but also one with perhaps the most hairstyle changes.

'The Demolition Man' has sported at least half a dozen different hairstyles over his 67-fight long MMA career. From giant mohawks to mini-mohawks to crew-cuts, Overeem has done it all. There is just something about the former UFC heavyweight contender's bullet-shaped head that whatever haircut he sports, it just doesn't suit.
#3 - Josh Koscheck
Josh Koscheck fought in the UFC for ten years before moving on to Bellator MMA in 2017. Koscheck never won a championship in his MMA career but came closest against Georges St-Pierre in 2012. He appeared on the first season of The Ultimate Fighter as a contestant and in the 12th season as a coach.
Throughout his MMA career, Josh Koscheck has sported one of the worst haircuts in UFC history. His bleached blonde hair with a curly texture made him look like a weird version of Pennywise from the movie 'IT.' The disparity between the color of his facial hair and hairstyle could make a hairstylist cringe.
While it is hard to say that Koscheck had a glorious MMA career, he did best some of the greatest MMA legends like Matt Hughes and Diego Sanchez. However, he could have had better fan support had he not gone with one of the worst haircuts in UFC history.
