If you have long hair, there are many options available for you. You can tie it up, cut it short, or micro braid it. Micro braiding results in a modern attractive look, and it consists of very thin overlapping braids that are much smaller than normal braids. Another modern day hairstyle for women with long hair is the French roll hairstyle. This is a simple but sophisticated style that consists of the hair being twirled, drawn back, and pinned around the back of the head in a roll. Use this style for job interviews or simply to prevent hair from getting in your face.
With respect to face shape, if you have a round shaped face, never choose a medium length hairstyle. Go for short or long, and omit bob shaped hairstyles all together. The key to choosing any of the modern day hairstyles for people with round shaped faces is to select a hairstyle that will decrease the overall round appearance of the face.
If you have long, straight hair with a round shaped face, keep it tapered to the side. This will make your face look longer. If you have short hair, go for a cute wavy style.
