When should a barber consider using heat protectant spray?

Using heat protectant spray is essential before applying heat to the hair with styling tools such as flat irons, curling irons, or blow dryers. The purpose of the spray is to create a barrier that shields the hair from the damaging effects of high temperatures. This protective layer helps to minimize moisture loss and reduces the risk of breakage, dryness, and split ends that can result from excessive heat.

While it is essential to consider hair health at all stages of a hair service, the most opportune moment to apply heat protectant is directly prior to the use of hot tools. This ensures that the product has time to form that protective barrier, enhancing overall hair integrity during styling. The other options, while they may involve important steps in the hair service process, do not directly pertain to the application of heat or the immediate protection of hair from thermal damage.
