Final answer:
A plastic comb is not suitable for use with curling irons as it can melt due to high heat. Metal combs or those made of heat-resistant materials are preferred for handling the temperature of styling tools.
Step-by-step explanation:
The type of comb that is NOT good for use with curling irons is a plastic comb. Plastic combs can melt or become damaged when they come into contact with the high heat from a curling iron. Instead, it is recommended to use a comb made of materials that can withstand high temperatures, such as metal combs or combs made from heat-resistant materials like carbon or silicone.
When styling hair with heat, you should always ensure that you're using the correct tools to avoid damage to your hair and your styling tools. A metal tail comb is often a preferred choice because the metal can handle the heat without melting, and the tail end is useful for sectioning the hair during styling.
Maintaining the integrity of your hair and styling tools is important, so always choose the right type of comb that can safely withstand the temperature of curling irons.
