Henna on 3c curls

So I'm thinking of hennaing my hair for the color. I've heard that henna can loosen ones curls which I don't want but I really want to color my hair with little to no damage done. I've colored my hair before with a box color and it loosened my 3c curls 3b/3a and made some completely straight in some places. So what I want to know is is the curl loosening guaranteed and is it permanent? Also is henna really worth it?
