It's not a soap that's for sale, nor will it ever likely be.
Silver Fox is a "product line" named after my father who passed away in 2010. He was a lot of things but part of what he was included being an artisan after he retired. So when I create something that gets "named" it gets that name in his honor. It was his nickname long before I started going gray.
I make a batch for myself, and give away a few cans from that batch. I'm happy people have enjoyed it enough to share their experience, and it's just a nice memory of my father. I have a more than full time job so no desire or time to add more "work." As Mike Rowe says: "when your avocation becomes a vocation you get no vacation." Giving a little back here and there to the B&B community however is more than fulfilling.
The only way to get it is for free. There are two cans being given away at the Kansas City Meet-Up.
Perhaps you could share your recipe?
