Cranial remolding helmets are typically recommended when an infant's head shape irregularity does not improve with repositioning techniques or if the asymmetry is severe. Conditions that may necessitate a cranial remolding helmet include [plagiocephaly]() (flattening on one side of the head), [brachycephaly]() (flattening at the back of the head), and [scaphocephaly]() (a long, narrow head shape).
