I've never done henna either. Hennaforhair.com had great info.
Henna dyes your hair PERMANENTLY. You can't bleach out the color and you may not be able to dye over it. You have to grow it out and then cut it off. You want to make sure you use body art quality (BAQ) henna. Other "hennas" have metalic dyes that can react to traditional dye. True henna only dyes red. You can mix it with indigo or amla to get different colors. You can only dye your hair darker then your natural color. For example, you cannot dye dark brown hair light red. `
Henna coats the hair. Because of this it can act similarly to a protein treatment, although henna has no protein. Cassia is similar to henna, but with no color (unless you have very light hair). Because henna coats the hair, it can make hair heavier and pull out some of your curl pattern.
