I'll second Ricky's advise and add a bit to it. Frist of all, if the
very crown of your Aleo is still intact it's chances of survival are
The individual leavf tips won't grown back, but the remaining healthy
tissue will still be able to produce energy to help the plant
recouperate, and though the main plant may not "make it" there is still
a high likelyhood that it will develop "pups" or new plants from the
roots and the base of the "mother" plant.
Keep the plant more on the dry side and when you do water it add a few
drops of "SUPERTHRIVE" to the water, water ir thoroughly and then not
again until it is dry (not DRIED OUT).
Place the injured plant is a warm spot with plenty of bright light but
no direct sun during the "heat" of the day. Early morning and late
afternoon sun are acceptable.
If the damaged leaves continue to show cellular damage, use a very
sharp knife or razor and keep it trimmed back beyond the damaged
tissues; you might also want to dust the cuts with agricultural sulfur.
Hope this helps and best of luck to you.
