Aspirin - Old and famous method to prevent dandruff?

Step 1
Crush two uncoated aspirin by folding them in a napkin and crushing them with the back of a metal spoon or grinding them in a pill grinder.

Step 2
Pour one capful of shampoo into a bowl. Use a fragrance-free, dye-free shampoo with as few ingredients as possible. Dandruff can be exacerbated by additives such as perfumes and conditioners.

Step 3
Add the aspirin powder to the shampoo. If you use more than a capful of shampoo to wash your hair, adjust the number of aspirin tablets accordingly.

Step 4
Stir the mixture well and use it to wash your hair. Leave it on for at least five minutes to allow the salicylic acid to exfoliate your scalp.

Step 5
Rinse the shampoo thoroughly from your hair and repeat if you wish. You can add 1/2 cup of apple cider vinegar to a pitcher of water and use that for the final rinse for extra dandruff-fighting power. There is no need to wash the vinegar out of your hair; the smell will go away as your hair dries.
