Washing your hair at least twice a week rinses off the excess oil and dirt on your scalp, and helps control sebum secretion.
Brushing your hair regularly will help evenly distribute the oil across your hairline, and will prevent your hair from looking oily.
Rather than blow drying your hair, which could lead to excess oil secretion, use a towel to dry your hair.
Made using ingredients like aloe vera and curd, a hair mask can help your hair stay shiny while getting rid of the oil.
If your hair tends to get oily, then not using hair oil during the winters is a no-brainer, as it will only make your oily hair problem worse.
Rather than using a generic shampoo or conditioner, consider using a conditioner tailored specifically for oily hair.
