Aspirin
Salicylic acid is one of the major constituents of aspirin. It is responsible for the anti-inflammatory properties of the drug. The acid is also a major constituent of many anti-dandruff shampoos. It plays a significant role in getting rid of the scaly skin and helps loosen flakes so they can be removed. A 4-week study showed the effects of salicylic acid on dandruff; 19 people with dandruff used two shampoos containing piroctone Olamine and salicylic acid or zinc pyrithione. The study showed that the two shampoos reduce dandruff, but the one containing salicylic acid was more effective in reducing the severity of scaling.
Another study showed that a shampoo that contains salicylic acid will improve irritation and itching in 10 people with scalp inflammation. To treat dandruff, you can try breaking two aspirin tablets and adding the powder to your shampoo before washing your hair.
Conclusion
Dandruff can be very difficult to treat. In severe cases, you may need the help of your healthcare provider. However, a variety of home remedies can help improve the symptoms and provide good scalp health.
