The hard rubber comb is the best choice for protecting a client from a hot curling iron due to its high heat resistance. Hard rubber does not conduct heat effectively, which means it can safely be used near hot styling tools without melting or transferring heat to the client’s hair or skin. In contrast, plastic, metal, and wooden combs may not provide the same level of protection. Plastic combs can sometimes warp or melt when exposed to high heat. Metal combs can conduct heat, increasing the risk of burns to both the stylist and the client. Wooden combs, while safer than metal, can be damaged by heat and may not provide a reliable barrier against hot tools. Using a hard rubber comb ensures that both the stylist can work effectively and the client remains protected from the risks of burns or damage from heat exposure.
