To make a hot oil treatment, warm a small amount of olive, coconut, jojoba or almond oil, and apply it to the hair. The oil should be tested to ensure it is not too hot before applying it.
To make a homemade hot oil treatment for dry or damaged hair, warm 2 tablespoons of olive oil, and apply it evenly to the hair. The safest way to heat olive oil is by immersing a small closed container of the oil in very hot water for several minutes. Allow the oil to remain on the hair for at least 30 minutes before washing as usual.
Those with fine or oily hair can use a lighter oil, such as jojoba or coconut oil, to hydrate hair. To make a hot oil treatment using coconut oil, melt 1/2 ounce of coconut oil, and apply the oil to wet hair. Allow the oil to remain on the hair for at least 10 minutes before washing as usual.
Any combination of oils, such as 1 tablespoon of jojoba oil with 1 tablespoon of almond oil, can be used to make a homemade hot oil treatment. Essential oils can be added to the base oil to treat hair and scalp conditions, such as dandruff, and to scent the base oil. To scent the base oil, mix 3 to 4 drops of the preferred essential oil to the 2 tablespoons of warmed oil.
