Question: 1 / 400

What is the effect of using heat protectant on hair?

It can lighten hair color

It protects hair from heat damage

Using a heat protectant on hair primarily serves to protect it from heat damage caused by styling tools such as flat irons, curling wands, and blow dryers. When hair is exposed to high temperatures, it can become dry, brittle, and prone to breakage. A good heat protectant creates a barrier that reduces the thermal load on the hair, preventing moisture loss and helping to maintain the hair's integrity.

This protective layer often contains ingredients that can resist heat, allowing the hair to withstand higher temperatures without sustaining damage. The effectiveness of heat protectants can significantly influence the longevity and health of styled hair, making them an essential part of any heat-based styling routine.

The other choices do not represent the primary function of heat protectants. While some products may alter hair volume or appearance, these are not the main benefits of heat protection. Similarly, lightening hair color or making it greasy are not associated with the purpose or benefits of using heat protectants.
