Every year hair cut styles change slightly as change marches on and since the only thing constant is change if you do not change with the haircut styles you will find it difficult to win friends and influence people.
Speaking of friends; the television show; "Friends" was certainly a trendy set of haircuts for 2005 wasn't it? But Friends TV sitcom series is no longer in style and those haircuts will soon be "has been" styles. You do not wish to be caught rolled over in your SUV and dead on arrival with an old haircut style do you?
For older men the Ronald Reagan haircut style is coming back in, especially as more balding men are working to get their hair back and as they do, they will want to show a healthy head of hair indeed. But believe it or not "Bald" will be back in too in 2006 and the Howard Stern "Shocked" jock look. You can achieve this I am guessing by waking up with matted hair, four afro comb brushes and then sticking your finger in a light socket. So that is about as simple as the Bald look, not much preparation needed their; a very low maintenance look indeed.
For women you can expect some longer looks to be trendy too, reminiscent of the Farrah Facet styles of the 80's but slightly shorter. Somewhat of a Britney Spears, Paris Hilton and Farrah Facet hybrid and this will work for Blondes and Brunettes equally well with brunettes being somewhat shorter by about 2-3 inches in length. Another look, which is already making its rounds is the "kick butt" short hair video action figure look. We will see much more of this in 2006.
