Any dark hair can be treated with laser

Laser hair removal can be used to permanently reduce hair growth in any area.  It only works on dark hair, and is best for lighter skin tones.  The laser targets pigment, which is why it is better for darker hair/lighter skin.  If you are treating an area where the skin is darker, or more pigmented, the results are not quite as good and the risk of discoloration or scarring is higher.

Laser hair removal can remove all unwanted hair anywhere on the body.  However, the hair has to be darker then your skin tone.  Since not all hair is in the active growth phase at one moment, sometimes more then one treatment to a given area is needed to get total hair removal.
