Depilatory creams DO NOT WORK!!! Not to mention as Lilith said, they hurt like hell. If you want something that gets rid of hair for 3 weeks or whatever, I'd say go with professional waxing. It might hurt, but it'll keep your gf hairless for a couple months. At least that's what I've been told. I've been thinking of getting it done, but i need to wait until I have some money. But anyway I don't suggest you go with the depilatory cream.
