I've been experimenting with this stuff on and off since October-ish. I've observed that it sandalore has grown hair on areas on my parts of temples that were completely bald, but never observed them go terminal. This is from my latest attempt following a procedure similar to jamesdunn. I have a mixture of 200g vanicream and 2g sandalore. I only apply it at night before bed and wash it out in the morning. The photo on the left is before obviously, about two weeks before.
I don't find it likely that it will grow beyond this length before falling out again, but we'll see.
