Lavender oil needs to be used by mixing it with olive oil and sesame oil. Before applying it on your hair, you need to dilute it. You can pour olive or sesame oil in a pot, and add ten drops of lavender oil or depending on the amount of sesame or olive oil we have poured in the pot. You can make a mixture of all these, and rub it on your hair roots, then apply the same mixture on the hair in general. Then you need to let the mixture sit on your scalp and hair for 20 minutes, perhaps by wearing bathing cape. You should then rinse your hair. Lavender oil will make your hair glossy, rejuvenate it, help it get moisture and oxygen, and keep it in shape.
