Anyway to keep horns secure without a full on chinstrap?

I want fake horns, but I want them to have any sturdiness in their actual placement on my head. The obvious answer is some kind of around the head harness, but I can't think of a way of keeping the from going back along my head than an obvious chinstrap. I don't expect full subtlty, but at least I can put the rest under my hair. Is there any not chinstrap option?
