A Little History
Only recently - the 30 yrs or so -has any hair type other than straight hair really been admired in the US, many women - women of color, jewish women and women of mixed ancestry still have negative feelings about their hair. They have grown up believing that straight hair is somehow inherently better than curly hair - well this is false.

The Men’s Long Hair Site. A site is dedicated to those men who take the effort to maintain their long hair, for themselves, or for others.

I’ve found a great site for womens hairstyles - it has hundreds thousands of pictures of hairstyles in loads of different catagories heres the link
I should warn you that its a pay site - like some kind of hair porn - They charge $9.99 a year to cover their bandwidth but their doing something right - They have over 25,000 members
Even better if you sign up through the above link they bung me some cash. Cha-Ching.

While looking for prom pics I found the above - I don’t speak polish so Im guessing its some kind of Prom Tiara:-)
Finding a prom hairstyle can be a daunting task, I suggest trying out as many prom hairstyles as you can to find the one thats right for you.
Examples of prom hairstyles
French Braid
This style may look impossible but with a little practice, this complicated braid can be accomplished in seconds rather than minutes. Once you have mastered the technique of French, or inverted, braiding, an endless number of variations are possible. This style works best on straight hair, wavy hair or fine curls. Very thick curly hair tends to give a bumpy appearance on the top of the head.
Check that you have equal tension on both sides of the braid, or you will end up with one side tight and the other side loose and floppy. You can ….. Read more of ‘Prom Hairstyles’ here

Its the biggest day of your life, you’ve looked forward to it forever - and now that moment is coming it fills you with dread - how should i do my hair - HOW!
Not like this—–>

In the past men have often adopted a style in their teens and kept it for the rest of their lifes - or at least until the dreaded male pattern baldness hits. These days men have far more options open to them - not nearly as many as women - but things are getting better.

My favourite mens hairstyles sites

Many women fear cutting their hair short, often having grown their hair long from an age before they chose their own hairstyles. Cutting your hair short can be a liberating experience, try one of the these great styles.

Two of my favourite short hairstyles.
Marcel Wave
An updated version of an old idea, the Marcel wave has been with us for a very long time; in the twenties and early thirties, every woman had rows of tight, elaborate waves that took forever to create. The style disappeared for a few decades but is now firmly back in fashion, and modem hair gel helps achieve a looser wave in minutes. The waves are actually formed between the side of a comb and your fingers, pushing together. With the hair gelled flat, these waves are only in one dimension. You don’t have to worry about body or a good shape (often ….. Read more of ‘Short Hairstyles’ here

Over the past few years I have noticed that some of the most searched for info on this website are all related to new hairstyles, 2003 hairstyles, 2002 hairstyles and so on. I have no doubt that in the future these will be replaced with 2004 hairstyles, 2005 hairstyles, 2006 hairstyles and so on. I think we all look for new hairstyles because we want to keep up with the trends and we want to be innovators. I have found that the best place to look for new hairstyles is TV - think the Jen anniston build up to each new season of friends.
Other New hairstyle sources
Magazines - They have the best stylists and like to promote change.

A great article about the trials of finding a good hairstylist if you have curly hair

“The trend toward more bountiful hair is at its height. Hair with volume is flattering to most face shapes and body types. It especially works for wavy, curly hair, going with hair’s texture instead of fighting it, which is always a plus.
Here, the latest trends, accompanied by home how-tos:”
