Heat the olive oil on low heat and add the grated ginger. Once the ginger turns brown remove from the heat and allow to cool. Once cool, strain the ginger out of the oil. You’ve got yourself ginger infused hair oil! Apply to the scalp for 5-10 minutes and then rinse thoroughly, follow with shampoo and conditioner.
You can substitute the freshly grated ginger with 1-2 drops of ginger essential oil to simplify the process even more.
