Dandruff may be the result of a dry scalp, or a skin condition called seborrheic dermatitis. It could also be caused by eczema, psoriasis, or, very commonly, an overgrowth of a yeastlike fungus called malassezia.
Drugstore remedies might include shampoos with zinc pyrithione, which targets fungus and bacteria; ketoconazole, which also fights fungus; coal tar and selenium sulfide, which slow the growth and die-off of skin cells on your scalp; and salicylic acid, which loosens flakes so they can be washed away. For some trusted natural treatments, read on.
Aspirin contains the same active ingredient (salicylic acid) as many medicated dandruff shampoos. Keep flaking in check by crushing two aspirins to a fine powder and adding it to the normal amount of shampoo you use each time you wash your hair. Leave the mixture on your hair for 1-2 minutes, then rinse well and wash again with plain shampoo.
Tea tree oil
Your kitchen could hold the key to an itch-free, flake-free scalp. Wet your hair and then rub a handful of baking soda vigorously into your scalp. Skip the shampoo and go right to rinsing. Baking soda reduces overactive fungi that can cause dandruff. Your hair may get dried out at first, but after a few weeks your scalp will start producing natural oils, leaving your hair softer and free of flakes.
Dandruff relief may be no farther away than your refrigerator. Just massage 2 tablespoons lemonjuice into your scalp and rinse with water. Then stir 1 teaspoon lemon juice into 1 cup water and rinse your hair with it. Repeat this daily until your dandruff disappears. Lemon’s acidity helps balance the pH of your scalp, which helps keeps dandruff at bay.
