*Tea Tree Oil, Lavender Oil, & Peppermint Oil [essential oils] (little) 
*Apple Cider Vinegar 
*Cod Liver Oil 
*Grape Seed Oil 
I really didn't measure, just estimated. On a scale of 1-5, 1 being the most & 5 being the least. Put the following in your hair after shampoo & do not rinse off; Then put water in your hair so you can makes sure it mixes well with your hair and spread it around. Leave on all day. Hair will smell a little like peppermint. You want to put as much as ACV in as you can but not to a point where your hair smells like vinegar. Peppermint should be the strongest smell out of all of them.
I put it in a big Aloe Vera bottle (the one you get at GNC)and mix it up. It's really good for the scalp as well as your hair!
