Hard (a.k.a. stripless) wax can be tricky to use, even for someone who is experienced using soft (a.k.a. strip) wax. Soft wax goes on fairly thin because the cloth or muslin strip that goes on top is going to help remove it. Whereas hard wax is heated at a lower temperature and goes on thicker (like the thickness of a nickel) because it hardens and becomes a strip in itself.
I've always used soft wax on myself for my eyebrows and lip. But just the other day I tried Wild Cherry Hard Wax by Satin Smooth (compare prices). I can't tell you how much I loved it even though it took a bit more skill than using the soft wax! It hurt much less than the soft wax. Usually I see more hair missed than I like because then I have to tweeze them. But because hard wax shrink wraps the hair, it maybe only missed one or two and my skin was barely red.
Just like any product all hard waxes aren't created equal. But Satin Smooth has very good waxes, they don't even require that you prep the skin with powder or oil to protect it because the wax has built-in buffers.
