1: Shampoo Each Day to Keep It Away What easier way to get rid of dandruff than to wash it down the drain? Getting rid of excess oils (which may contribute to the overgrowth of malassezia in the first place) and flakes through daily shampooing may be the easiest way to tame your mane. 2: Switch Shampoos If your regular shampoo isn't doing the trick, even with daily washing, it's time to switch to an anti-dandruff shampoo. Check the ingredients in over-the-counter dandruff shampoos, and look for one that contains zinc pyrithione, which can reduce the fungus; selenium sulfide, which can limit cell turnover and possibly even decrease the amount of fungus; salicylic acid, which works as a sort of scrub to slough off dead skin; or ketoconazole, which works against a broad array of fungi. 3: Go for Three Your favorite dandruff shampoo may stop working after a while, and those little flakes may return. Don't blame the shampoo. You simply may have built up a resistance to its active ingredient. To prevent this, try rotating three brands of dandruff shampoo (each with a different formulation), using each for a month. In other words, use one shampoo for a month, then switch to a second brand for a month, then to a third brand for a month, then back to the original shampoo for a month, and so on. 4: Lather Twice The first lathering and rinsing gets rid of the loose flakes and the oily buildup on your hair and scalp. It sort of clears the area so the second lathering can get to work. Leave the second lathering of shampoo on your hair at least five minutes before rinsing it off. That gives the shampoo a chance to penetrate the skin cells and do what it's supposed to do. 5: Try Tar If the anti-dandruff shampoos aren't working, it's time to bring out the big guns, namely the tar shampoos, which have been a proven remedy for more than 200 years. The tar decreases cell turnover quite effectively, though there are some drawbacks. Tar shampoos have a strong odor, may stain the shaft of lighter-colored hair (it can take weeks of using a milder shampoo to get rid of the discoloration), and may irritate the skin. 6: Use a Rinse If you decide to go with a tar shampoo, rinse your hair with lemon juice, a conditioner, or creme rinse to get rid of any lingering odor from the shampoo. Using a hair conditioner after washing with any anti-dandruff shampoo is a good idea anyway, because the medicated shampoos tend to stiffen hair and make it less manageable. Many of them also dry the scalp, which can add to flaking; a conditioner can help seal in nourishing moisture. 7: Be Sensitive to Your Sensitivity There are some people who just shouldn't use a tar shampoo. Why? Because they're so sensitive. Rather, their scalp is, and a tar shampoo can irritate and inflame their hair follicles, causing a condition called folliculitis. The cure? Switch to a milder shampoo. 8: Stop Those Itchy Fingers Try to resist the temptation to go after those itchy patches like a dog chasing fleas. You may end up with wounds to your scalp caused by your fingernails. If you break the skin on your scalp, discontinue use of medicated shampoo for a while. Switch to a mild shampoo, such as a baby shampoo, and use it daily until the scratches are healed. 9: Shower Away Sweat After exercise or strenuous work that makes you perspire, shower and shampoo as soon as possible. Sweat irritates the scalp and speeds up the flaking of skin cells. 10: Go Easy on the Sticky Stuff Although you needn't give up the various mousses, sprays, and gels that hold your hairstyle in place, try to use them less often. These hair products can contribute to oily buildup. Source
