If the wool has, indeed, been effected by the very high heat, then I doubt there is anything that can be done to alter this......but, soaking them in fabric softner,etc wouldn't hurt to try.... (I'd just try it on one, to see.) But, think of a wool sweater that has been put, by accident, into the drier...there is nothing that can make it as it was before.
I'm just so sorry this has happened...what a pity! Did you administer a good pinch to your husband?

Unfortunately, your scarves are now felted and there's really no way to revive them. I know that they don't like you meant them to look, but are they ruined or just different than you intended? I went on-line and took a look at the recommended care instructions for this yarn, and it was pretty clear that it should be hand washed in cold water and dried flat, so I'm guessing that this yarn is prone to felting if exposed to heat and agitation.
