Dandruff can be a common ailment, and having a healthy, flake-free scalp is an important part of hair health. Lemongrass oil is an effective dandruff treatment, with one 2015 study finding that it significantly reduced dandruff after one week.

Lemongrass oil for dandruff is most effective when used daily. Mix a few drops into your shampoo or conditioner daily, and make sure it’s massaged into your scalp.
