Stop your hair from looking greasy by switching shampoos, shampooing twice, powdering hair and correcting hormonal imbalances. Keeping hair cut in a short, layered style is another option for excessively greasy locks.
Consider switching shampoos to improve the appearance of greasy hair. Anti-dandruff shampoos that contain ingredients, such as zinc pyrithione or salicylic acid, help to reduce scalp oil. When shampooing hair, lather shampoo and massage into the scalp. Leave the shampoo on hair for at least 30 seconds before rinsing out and shampooing the hair a second time. Style the hair immediately after towel drying for maximum volume.
Dry shampoo may be used between shampoos to reduce excess oil on the scalp and hair. Powder shampoo may also be used immediately after washing and styling to prevent oil buildup. A quick fix is to powder the roots of the hair with baby powder or loose powder. Make sure to blend the powder into hair so that it is not visible.
An excessively oily scalp may be caused by hormonal imbalances that increase the scalp's sebum production. Consult with a physician to determine possible treatments to correct the imbalance. Birth control pills may be a viable option for some women.
