Oily hair can be a matter of degrees. In some cases, you tell just by the sight that someone is affected by extremely oily or greasy hair whereas, with others, it is something only they themselves know.
Depending on the degree of the problem, you can decide on a number of different approaches to dealing with what many consider a real hair problem. One approach to your oily hair is to simply leave it alone and accept that it is natural to you.
Oily hair can be caused by a number of factors, some of which you possibly cannot or will not change. For example, do you constantly touch your hair with your hands? If so, you are more likely to have greasy hair. Even your diet can make a difference in the texture and feel of your hair. So you may come to the conclusion that accepting you have oily hair is the way forward.
If you feel you cannot put up with your greasy hair, the only sure way to deal with it is to wash it regularly. Washing your hair once will probably not be enough if you are especially affected by oily hair. You have possibly experienced the difference between one wash and two when washing your hair in the shower or the bath.
You can just feel the difference on the second wash. Your hair will feel much smoother and your shampoo will lather up more on the second wash. For those who have extremely greasy hair, Washing hair may have to be more regular than those who do not have the problem. Most people will wash their hair in the shower every morning although some people will intentionally avoid washing their hair too often.
Oily hair can be a significant problem when it has a definite effect on how your hair sits naturally. Often it will stay flattered and lose its bounce when it becomes overly oily. Using mousse or gel never really solves the problem and sometimes even exacerbates the problem.
A good thorough wash is the only real way to deal with oily or greasy hair and the greater the problem, the more you will have to wash. Should you consider your hair to be oily but not to an extreme, you may decide to leave well alone.
Try to keep your hands out of your hair whenever possible and even look at how your diet might be contributing to your oily hair. Other than that, all you can do is find a good shampoo, wash twice or even three times and above all, accept that hair will differ from person to person and that you just happen to be one who has oily hair.
