You have long shag hairstyles, medium shags and short shags. You should keep in mind that the shaggy hairstyle is not just going to happen and it may be hard to achieve on your own, unless you know what you are doing.
For that shag hairstyle that is flawless, you will need to go to the stylist who will be able to determine just what type of shag hair cut is going to look the best on you. The stylist that is skilled will be able to cut the shattered hair layers in order to thin out even the thickest hair and add volume to the hair at the same time.
If you are looking for medium shag hairstyle, then you should keep in mind that this looks good on most people, except for those individuals that have hair that is very frizzy or curly. This is because the layers will adjust in order to suit the shape of the face.
