Dandruff may be the conclusion 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 moderate the growth and die-off of skin cells on your scalp; and salicylic acid, which loosens flakes so they can be washed away.
Dandruff maintanance may be no farther away than your refrigerator. Just massage 2 tablespoons lemon juice 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.
The abrasiveness of natural table salt works great for scrubbing out dandruff flakes before you shampoo. Grab a saltshaker and shake some salt onto your dry scalp. Then work it through your hair, giving your scalp a massage. You’ll find you’ve worked out the dry, flaky skin and are ready for a shampoo.
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.
