Heat protectants are specifically designed to shield the hair from the damaging effects of high temperatures associated with styling tools, such as flat irons, curling wands, and blow dryers. When applied to the hair before using these tools, heat protectants form a barrier that helps prevent moisture loss and reduces the risk of heat damage, ensuring that the hair remains healthy while achieving the desired style.

Moisturizers are generally used to hydrate and nourish the hair, but they do not provide the specific thermal protection needed for styling. Texturizers are products intended to change the texture of the hair, such as making it curlier or straighter, rather than preparing it for heat styling specifically. Primers can be used for various purposes, such as smoothing the hair or enhancing the effectiveness of other products, but they do not serve the primary function of protecting against heat damage. Thus, heat protectants are the most suitable choice for preparing hair for styling with heated tools.
