The product that is typically used for thermal protection during heat styling is heat protectant spray. This specialized formulation is designed to create a barrier between the hair and the high temperatures generated by styling tools, such as blow dryers, curling irons, and flat irons.

Heat protectant sprays generally contain ingredients that can help reduce moisture loss and prevent the hair from becoming dry or damaged due to heat exposure. They often include silicones or oils that coat the hair, reflecting heat away and sealing in moisture, which maintains the hair's health and integrity during styling.

While other products such as hair gel, hair serum, and deep conditioner serve valuable purposes in styling and hair care, they do not specifically provide the same level of thermal protection as heat protectant sprays. Hair gels primarily offer hold and style; hair serums can enhance shine and manage frizz but are not specifically formulated for heat protection; and deep conditioners are used mainly for moisturizing and repairing the hair rather than providing a protective barrier against heat.
