Open up and there you go, if it's a little too long, you can just press it on the sides (a dab of coconut oil or butter, or coconut spray holds things in place!).
In a spray bottle, combine 8 ounces warm water, 2 teaspoons coarse sea salt or Epsom salts, 1 teaspoon gel (for hold) and 4 or 5 drops of moisturizing coconut oil (which will also provide a yummy tropical scent).
