While Paul Mitchell Tea Tree Special Shampoo can be an effective way to reduce dandruff, tea tree oil can also be an irritant. According to Sulfate-Free Shampoo Brands, tea tree oil can cause rashes and allergic reactions. Its antiseptic properties can be too strong for sensitive skin. Tea tree oil products that are too harsh can be ineffective.
Sulfate-Free Shampoo Brands states that tea tree oil has anti-fungal and antibacterial properties that can reduce dandruff. It helps fight against fungi that cause dandruff and seborrhoeic dermatitis; but it may not work on all types of skin.
There are a number of dandruff banishing alternatives. According to Paula's Choice Skincare, the best way to get rid of dandruff is to use an anti-fungal agent, such as zinc pyrithione, coal tar, selenium sulfide or salicylic acid. Anti-fungal agents reduce dandruff by attacking fungus. Look for products that contain ketoconazole. Zinc is another effective anti-fungal agent. It can be found in popular, over-the-counter brands, such as Head and Shoulders and Selsun Salon.
According to Paula's Choice Skincare, coal tar controls dandruff by slowing down the death rate of skin cells. It has an unpleasant smell and texture, but it is a good way to rid your scalp of dandruff. Selenium sulfide works in a similar fashion, but its smell is less noxious. This is a good option for people who want the results of coal tar without the unpleasant odor; plus, this ingredient can be found in Selsun Blue shampoo. Paula's Choice Skincare lists salicylic acid as another great way to get rid of dandruff. This exfoliant removes excess skin cells before they turn into flakes of dandruff.
