1. A hair care device for styling a strand of hair including a hair cuticle surrounding a hair cortex having melanin granules, the hair care device comprising:
a hinged housing having opposable parts that open and close to receive the strand of hair;
a source of heat within an opposable part of the opposable parts, wherein the source of heat is operable for heating both the hair cuticle and the hair cortex of the strand of hair;
a source of radiation arranged within the opposable part of the hinged housing, wherein the source of radiation is operable for only radiating the hair cortex of the strand of hair, wherein the source of radiation is configured to emit radiation over a duration less than a thermal relaxation time of the melanin granules to heat the melanin granules;
wherein the source of heat and the source of radiation are arranged relative to each other for a combined heating and radiating of the hair cortex of the strand of hair;
wherein the source of heat and the source of radiation are arranged to create a combined heating and radiating effect on the strand of hair such that the strand of hair is heated from the inside;
wherein, during the combined heating and radiating of the hair cortex of the strand of hair, the source of heat is configured to heat the hair cuticle of the strand of hair up to a first temperature of no more than 150° C.; and
wherein, during the combined heating and radiating of the hair cortex of the strand of hair, the source of radiation and the source of heat are configured to heat the hair cortex of the strand of hair to a second temperature of more than 150° C. to about 170° C.
