Bar soap if your skin can tollorate it.

But I’ve used a few shaving products (and razor) from the Canadian owned and operated Rocky Mountain Barber Company, and their stuff is also Made in Canada: https://rockymountainbarber.ca/collections/mens-shaving-creams

While not explicit, I believe all their shaving products are vegan. Their listed ingredients don’t alarm me, and their shave bar scored really well on the EWG Skin Deep rating.
