What is a recommended practice when using hot styling tools?

Using a heat protectant spray
Applying oil directly to the hair
Styling hair when it is wet
Skipping heat protection altogether

The correct answer is: Using a heat protectant spray

Using a heat protectant spray is an essential practice when using hot styling tools because it helps shield the hair from the damaging effects of high temperatures. When heated, hair can lose moisture and become brittle, leading to breakage, split ends, and overall damage. A heat protectant spray forms a barrier over the hair shafts, significantly reducing moisture loss and preventing excessive damage, thereby maintaining the hair's integrity and health. The other options do not provide the same level of protection. Applying oil directly to the hair may improve shine and manageability but does not offer the necessary thermal protection needed when using high-heat tools. Styling wet hair with hot tools can cause severe thermal damage, as the water inside the hair can steam, leading to swelling and potential breakage. Finally, skipping heat protection leads to cumulative damage over time, making it a harmful choice for hair health.
