Classic shag haircuts add a trendy, edgy twist to your look and bring your hairstyles to the next stage. In any length, a shag is fantastic: short shaggy hairstyles are incredibly sassy and sexy, you can easily get on-trend disheveled looks with a medium shag haircut, whereas long shag haircuts are popular for their amazing all-over layers. Shags on thin and coarse, curly and straight hair are equally fine. Shag haircuts improve volume for fine hair, and curly shag haircuts are perfect for overcoming recalcitrant frizz.
