My real uggs have been in the rain, they aren't soft anymore and have creases in? is it too late to fix?

i have been out a few times when it has been raining, now my uggs have gone hard on the outside and have creases around the front area? i heard getting the ugg protector can help but is it too late? can this fix it if i use the shampoo or protector etc?? i have been in contact with asos who i bought them from and they said i should of used the protector but they didnt make it very clear!
