If you’ve got a dandruff problem, don’t run out and buy pricey medicated shampoos. Look first for remedies in your own home. Check out 7 tried-and-true ways to get rid of pesky dandruff once and for all:

Aspirin

Aspirin actually contains the same active ingredient as many dandruff shampoos. Just crush two aspirin tablets into a fine powder, then add to the normal amount of shampoo you use when you wash your hair. Leave the mixture in your hair for a minute or two before you rinse and wash again with normal shampoo.

Baking Soda

Baking soda cane come to the rescue in many ways around the home, and if you’ve got dandruff, you should bring it in to the shower as well. Just wet your hair and rub a handful of baking soda vigorously into your scalp. Then rinse and skip the shampoo step. According to Reader’s Digest:

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.

Apple Cider Vinegar

Among its many other helpful uses, this stuff can help wonderfully to change the pH of your scalp, making it more difficult for yeast to grow there. Give yourself a treatment twice a week by mixing 1/4 cup of apple cider vinegar with 1/4 cup of water in a spray bottle. Spritz all over your head, then wrap your head in a towel and let it sit for 15 minutes to an hour. Then wash you hair as you normally would.

Mouthwash

The anti-fungal properties in mouthwash can help defeat dandruff-causing yeast from growing. Wash your hair with your normal shampoo, then rinse with an alcohol-based mouthwash. Follow with your normal conditioning routine.

Coconut Oil

Here’s a great dandruff treatment that also smells great. Just massage 3-5 tbsp of oil into your scalp before you shower. Let it sit for about an hour before shampooing naturally.

Lemon

Massage 2 tbsp of lemon juice into your scalp, then rinse right away. Stir 1 tsp of lemon juice into 1 cup of water and rinse your hair with it. Repeat this daily to help balance the pH of your scalp and keep dandruff at bay.

Salt

Rub some salt onto your dry scalp and massage thoroughly before you shampoo. The abrasiveness of regular table salt will help to scrub out dandruff flakes before you shampoo.
