* Change your pillowcase once a week. Oil, dirt and bacteria from your head, hair and face can build-up on pillowcases over time, so even if you go to bed with a freshly washed face, you may have a bad case of pimples, acne or black heads because you may be exposing yourself to unwanted oil and dirt overnight. To avoid this, replace your used pillowcase with a freshly washed one once a week
* Wash your hair frequently. Having greasy hair can contribute to more oil on the surface of the skin, increasing the chances of blocked pores. As well as washing your face, you need to ensure that you are washing your hair on a regular basis, thus preventing excess oil from building up on the face. Washing every two to three days should be enough for most people, unless you tend to have very oily hair.
* Remember that over-washing your hair can actually cause your body to produce more oil to compensate. Washing everyday is an overkill for most people.
* Dab on a little tea tree oil. Tea tree oil is a natural essential oil which has been proven to combat whiteheads, blackheads and pimples just as effectively as benzoyl peroxide. To use, just dab a little of the oil directly onto the whiteheads etc by using a q-tip ( ear bud) If you find this too strong, you can dilute the tea tree with a few drops of water.
