I don't think the small amount of magnesium oil will over moisturize you. Magnesium sulfate (Epsom salt) is easy to pick up at the drugstore. Try that first. I would suggest that you make a bunch of FSG, freeze it in 4 oz portions and add ingredients based on the previous 4 oz. You'll never know what's perfect for you until you try it and monitor and adjust. Remember hair needs change based on the season, so what works now may need to change in the Fall.
