Part of it is following age indications on the product/doll, so that hair is less likely to be an issue. (At age one & two, my daughter's cloth dolls all had either yarn braids that were well-fastened or little "tufts" of "hair" showing out from under an attached cap.) After we got dolls for 3+, I realized the difference, and why.
But as for how to keep it nice, a good doll brush (or synthetic wig brush) & some spray conditioner or de-tangler (which I would use only if misting the hair with water before brushing isn't sufficient) can help with maintenance. But....maintenance is key, & necessary. lol
Don't just "comb it out." Take a section of hair, spray with water, & start at the ENDS. Work your way up from there. (This is probably in those wig care instructions.)
People who rehab American Girl dolls have lots of info on wig upkeep & also tips for addressing badly neglected doll hair, so that can be a good resource online.
