No 1. Baking Soda.
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.
No 2. Aspirin.
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.
No 3. Coconut Oil.
Research says coconut oil is a "tried and true" dandruff treatment, and it smells nice too. Before showering, massage 3-5 tablespoons of coconut oil into your scalp and let sit for about an hour. Shampoo normally. You can also look for a shampoo that already contains coconut oil.
No 4. Tea Tree
Research made it clear that shampoos with just 5 percent tea tree oil significantly improves the severity of dandruff. You can also add a few drops of tea tree oil to your favorite shampoo as you wash normally.
No 5. Lemon.
Dandruff relief 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.
These are the five few natural home remedies that can help you eliminate dandruff.
