Using a heat protectant spray or serum is essential before applying heat tools like curling irons, straighteners, or blow dryers. These products are specifically designed to create a barrier between the hair and the high temperatures generated by these tools.

Heat can cause significant damage to hair, including dryness, brittleness, and split ends. Heat protectants work by either coating the hair strands or by infusing protective ingredients that help to minimize moisture loss and prevent overheating. This helps maintain the overall health and integrity of the hair while allowing for styling flexibility.

In contrast, hair gel, conditioning cream, and hair mousse are primarily used for styling rather than for protection against heat. While they may provide hold, moisture, or volume, they do not offer the necessary defense against the damaging effects of heat application. For optimal hair care and styling results, the use of a heat protectant is highly recommended.
