Using a heat protectant spray is essential for protecting hair during thermal styling, such as blow drying, curling, or straightening. These sprays are specifically formulated to create a barrier between the hair and the heat source, which helps to minimize damage caused by high temperatures. They often contain ingredients that can help to strengthen the hair, retain moisture, and improve overall health while reducing frizz and enhancing shine.

In contrast, shampoo is primarily used for cleansing the hair and scalp, and does not provide any protective qualities against heat. Conditioner works to moisturize and detangle hair, but it does not have the specific heat-resistant properties needed for thermal styling. Gel is mainly used for styling and holding hair in place, but like shampoo and conditioner, it does not offer thermal protection. Therefore, the heat protectant spray is the most effective choice among the options provided for safeguarding hair during the use of heat styling tools.
