Once you relax it, I would say learn how to rollerset, use minimal direct heat and get a regimen going that consists of mositure and protein. Also be patient and gentle with your hair and never try to do freshly relaxed styles with a head full of re-growth, that just causes breakage (e.g. a slick tight ponytail will be harder to acheive on 12 week post hair than it would on 2 day post hair). Try to maipulate your hair as little as possible also..
