Data recovery on mac SSD - is it possible?

Hi all,
I've been asked if i can recover files that have been deleted by Disk doctor on a Macbook air. No backups have been made.

I've got all the software for PC's but not had to do this on a mac ssd.

Do ssd's overwrite data in a different way to hdd's and is there any software that can do this like getdataback or fotorec?

cheers
