We don’t normally make business predictions here at HuffPost Canada Style but it seems inevitable that the manufacturer of Spiker Hair Gel will go out of business now that “Jersey Shore’s” DJ Pauly D has given himself a hair makeover.

The hair that rocked the world and incredibly took only 25 minutes to sculpt, was replaced last week by a sleek, sophisticated 'do.

The 32-year old reality star isn’t the first male celebrity to give the world a shock by getting rid of their signature locks. “Suit and Tie” singer, Justin Timberlake, swapped out his ramen noodle-esque curly blond hair years ago, most recently showing off a dapper new look with straight hair that the late Carey Grant would be very proud of.

“Silver Linings Playbook” babe Bradley Cooper decided to take a hint from Justin Timberlake circa 2000. The Oscar-nominee has been spotted on the set of his new film with a perm that would rival Little Orphan Annie’s.

Another life changing hair transformation was teenage dreamboat and Canadian shit disturber, Justin Bieber, who made headlines when he changed his iconic side swept bangs for a more grownup, out of his face hairstyle. Selena Gomez’s on and off beau also appears to have acquired a mini six-pack and a major attitude problem along with his new hair.

It’s not just the young bucks who are making dramatic changes to their mops. Even older leading men are causing a paparazzi frenzy with their hair transformations.

We’ve been seeing a lot of Kid Rock lately in the tabloids but wait, that’s not Kid Rock! That’s Brad Pitt sporting long hair in a ponytail along with his signature scruff. The “Fight Club” actor could have been mistaken for a number of longhaired rockers, including Axl Rose with his latest makeover.

We can’t leave out “Lord of the Rings” actor, Viggo Mortensen whose long wavy hair became synonymous with his on-screen character Aragorn. The "Eastern Promises" star has also experimented with extremely short hair.

Hair makeovers are always a great way to start off the summer season and a new look clearly isn’t just for the ladies. Let's take a look at some of the best male celebrity hair makeovers and make appointments with our hairstylists stat.
