A major product to care for your shag hairstyle is the conditioner. Apply a half- dollar size amount into the roots and leave it in for some time, rinse thoroughly and pat dry with a soft towel. It is important to know your hair quality, if you have thick hair, pick up a conditioner that softens and is anti-frizz. For thin and frail hair, use a conditioner which says fragile or thickening to add volume to your hair. It is also important to apply the conditioner directly to the roots or better still apply a leave-in conditioner. When blow drying your washed hair, apply heat directly to the roots flipping your head downwards. This will add volume to the hair and accentuate the shag hairstyle.
