The best way to use the oils for maximum effect is to combine all of the oils that you know will have the best effect for your hair. There are also many other oils that I have not mentioned so you may want to do more research about this and as I come up with more oils I will also add to the list.
For financial reasons and since oils can be expensive you may only want to invest in the cost of the oils that are the best for your hair type. You should purchase a clear or opaque spray bottle from a store such as the Dollar Store and add the oils about half way in the bottle. Fill the rest of the bottle with water. Each time that you use the oil and water combination, make sure that you shake the bottle so that the oil and water are well combined.
Oil and water do mix. You just need to shake the combination of the oil and the water and then it will mix. This will add the best effect for your hair with the oils and the water and keep your hair very healthy. Do not forget to also massage your scalp daily to promote hair growth.
