It really helps with the frizz, but not so much with the curls underneath. I have enough for one more treatment. Not sure when I want to try it again. I think I'm not getting the iron hot enough. I can't see the temperature on it.
From Michael Berg:

Every person has a unique connection to the Creator that can never be extinguished, and every person has a great soul that can manifest important things in our world. To make a person feel less than they are because of something inside themselves, be it faith, race, or sexual orientation, is the greatest sin of all."
