Hair that is oily tends to be limp, greasy in appearance, and difficult to style. This is caused by an overproduction of sebum, which is the oil that is produces by the sebaceous glands located in the scalp. An increase in sebum production can occur for a variety of reasons; hormone imbalance, poor nutrition, and as a side effect from some medications. Over-productive sebaceous glands can also be a matter of genetics.
Since there’s little you can do in terms of decreasing your scalp’s sebum production, most treatments for oily hair call for the use of special shampoos and haircare products. There are a variety of shampoos on the the market that are specially made for oily hair types, but it is important to make sure that these products are safe for color-treated hair if you choose to color your hair. Most shampoos for oily hair are stronger than average shampoos, and may cause premature color fading.
For hair that is only slightly oily, it may be possible to treat this condition by shampooing every day with a quality shampoo. Since the scalp constantly produces oil, the longer you go between shampooing, the more oily your hair will be. If you color your hiar, however, be sure to use a color-care shampoo.
If your hair is moderately oily, you may need to switch to an oil-control shampoo. Many of these shampoos are minty in fragrance, and often include tea tree oil, peppermint oil, and other minty ingredients. Paul Mitchell Tea Tree Shampoo is a great product for moderately oily hair. It effectively cleanses the hair and scalp and is still relatively mild. Biolage Normalizing Shampoo is another product that works well.
For hair that is severely oily, it will be necessary to switch to a medicated shampoo. These shampoos often contain zinc pyrithione, an ingredient which is found in many dandruff shampoos. These shampoos should be used daily, and since they are strong in nature, it is a good idea not to color or perm your hair while using them.
Since shampoos and over-the-counter products can only do so much, if you need something stronger than a medicated shampoo it might be advisable to see a dermatologist. Chronic oiliness may indicate a potentially serious health problem. A dermatologist may also be able to prescribe a prescription-strength product.
