The great news is that there are indeed no rules of hairstyling in this day and age when you have fine hair and square face. Hairstylists usually vary in their suggestions and opinions on how to best style square face and fine hair, yet most will certainly agree that round faces need simple hairstyles, oblong faces need width, and square faces need just a little bit of softening effect.
The main key to a great hairstyle is to find a certain style which flatters you and which can work well with your square face and your fine hair. If you do not know where to start, then the ideas below can help you to come with one style to pull off.
First, you can try the Concave Bob. There is no doubt that short concave bob, which has sides to fall forwards and can soften the jaw line has to be adorned with diagonal bangs in order to reduce squareness.
This particular hairstyle can help you to round out the face since it can frame and soften your square feature.
You can try the wispy, swept-across bangs with waves or curls which are nicely added to bring in more dimension to this hairstyle.
The other hairstyle to try is the Shag. Keep in your mind that the ideal length of your hair, if you have square-shaped face, is about one to two inches right below your jaw to shoulder length. A hag cut can fit this suggestion perfectly.
The resultant shag style has wispy, soft sides which should fall right around your jaw line.
