A hot comb is a styling tool that allows women with coarse or extremely curly hair to achieve smooth, straight locks without resorting to chemical straightening or relaxers. It is a heat conductive metal comb that should reach temperatures of approximately 65 degrees Celsius, and then slide through the hair, restructuring it in to a new straight shape.
The combs are heated either by an electrical charge or by direct application to a heat source. The comb, once heated, should be handled with caution, so ensure you avoid any burning of the skin by always holding it away from the scalp. To avoid any undue strain on the hair, the use of a heat protector spray is recommended, as it will maintain the condition and shine, whilst also improving the hold on the straightened look.
To use the comb effectively, section the hair into small pieces, beginning at the nape of the neck and working up wards towards the crown and the face. Working one section at a time, place the comb in at the root, and comb slowly down towards the tips of the hair. Continue combing until the hair is at the desired appearance; lay it gently down against your shoulder till it completely cools. Any disruption of the hair whilst still warm will affect its final straightened appearance. Once cool, release the next section of hair and repeat the process until the whole head is complete. The style will last until your hair is next wet or heated. To protect the hair from humidity, thus returning the natural curl, finish the style with hairspray.
