Unexpected Reasons You Have Greasy Hair

Yep—blame it on Aunt Flo. As if your monthly menstruation didn’t already wreak havoc on your appearance, hormonal fluctuations can cause your oil glands to go into overdrive. As a result, your scalp may feel more greasy than at other times during the month. This is also the same reason that you may develop acne breakouts. I recommend trying a salicylic acid shampoo to help remove excess oil from the scalp.



Throwing your hair back in a ponytail might be a quick way to cool off and get your hair off your neck, but experts warn that this low-maintenance style can actually make hair look greasier at the roots. Pulling the hair together in a ponytail may lead to the accumulation of oil and dirt on the scalp underneath the ponytail holder. Essentially, oil, dirt and grease get trapped in the tiny crevices between your strands because the rubber band serves as a roadblock. When it’s hot as hell, it makes sense to pull your hair back, but doing so can make grease pool on your scalp. If your hair is matted down your scalp may not be ‘breathing’ and oil may not spread through the hair shaft. Let your hair down more to combat accumulation.



There’s a reason more and more hair-care brands are marketing products to specific hair types: Everyone’s hair is different and requires a different balance of ingredients. Using the wrong products for your hair type or overusing those products can cause a buildup of product that ends up irritating the scalp. That this buildup of product at your roots can trap oil there and make your hair feel greasy. To prevent this, Louis recommends looking for styling products that are lightweight and absorb thoroughly into the hair. You can also try using a clarifying shampoo once a week. A clarifying shampoo gently cleanses away any product buildup or outside pollution buildup in your hair.



If you’re sick and tired of your greasy locks, your instinctual reaction might be to shampoo it on the reg.  Over-washing can quickly lead to more oil. Over-washing your hair strips your hair and scalp of natural oils. The body remedies this by producing even more oil to make up for lost oils, which then creates a buildup and makes your hair feel and look oily. Not sure if your excess grease is the result of over-washing? I suggests going a day or two without washing and seeing what happens—or, only washing your hair once or twice a week.



Reyman points out that oil from the scalp slowly moves down the hair between washes, conditioning the hair shaft from roots to ends. Brushing helps this happen more thoroughly by spreading oil along the length of the hair with each stroke. But many people with curly hair don't brush their hair (or do it infrequently). If you aren’t brushing your hair, oil will start accumulating around the scalp. In some cases this means oily scalp and dry ends. Also points out that another reason for more grease when your strands are curly is that you might be tempted to wash it less, since it likely holds volume and texture days after a shampoo. But this only gives the oil more of a chance to accumulate on the scalp and the hair itself.



You might think that if you have dandruff or scalp psoriasis, that dry itchy skin means your hair will be dry, too. But that both of these conditions might seriously contribute to greasy locks, and it's a bit of a vicious cycle. Scalp oil promotes an overgrowth of yeast on scalp skin, which in turn promotes inflammation and flaking. This may further trap oil and make the hair look greasy. Your best bet is to use a scalp-friendly shampoo and conditioner.
