Using a heat protectant is essential when applying heat tools to hair, as it creates a barrier between the hair and the high temperatures emitted by devices such as blow dryers, curling irons, and flat irons. Heat protectants often contain silicones and other ingredients that can shield the hair cuticles from damage, reduce moisture loss, and help maintain the hair's natural shine and texture. This practice helps minimize the risk of breakage, dryness, and other heat-related damage that can compromise hair health.

Applying oil before using heat tools, while beneficial in some contexts, does not provide the same level of protection as a dedicated heat protectant, which is specifically formulated to withstand high temperatures. Using the highest temperature setting available can lead to unnecessary damage, particularly for finer or color-treated hair, which is more susceptible to heat damage. Additionally, using heat tools on dry hair is not a universal guideline, as certain techniques, like blow-drying, may require some moisture for effective styling while minimizing damage. Thus, the use of a heat protectant stands out as the most critical guideline in this context.
