Identify the cause of the problem as transplanting can disturb the roots and can make things worse. Evaluate and rule out some of the possibilities:

Dracaena leaves may curl due to low humidity, high temperatures, too much sunlight, improper watering (increase the amount of water in the summer but decrease it when temperatures recede; do not water if the soil is already moist or soggy; do not let water collect in the pot's saucer), too much fertilizer, lack of nutrients, pests and diseases.

When to water: wait for the soil to feel dry to the touch (as opposed to watering on a schedule every "x" days).

You need to know the moisture deep in the pot. Use a chopstick or wooden dowel stuck down deep and if it comes out moist don’t water.

what you need is to provide us a pic.. so we can actually talk about your plant.. rather than vague generalities ...

my usual answer would be to propagate the growth tips.. and once rooted.. throw away the old mess ..
