Answer
There is no simple answer to this. How many treatments you will need will mostly depend on your hair and skin type. If you're light-skinned, lighter than type III or so, high settings can be used on LightSheer, which will probably kill more hair at one time. If you're darker skinned, lower settings will need to be used. Yags are a bit less powerful because they are meant for darker skins, darker than type IV, so they're not as effective on fine hair. But on coarse hair, they work just as well as LightSheer.
