Think about your hair type.

I may sound like captain obvious when I say this, but products that are suitable for fine hair types may not be the best choice for those with thick, curly hair. Those who have the former will want to opt for lighter formulas, like sprays, which will protect your hair without weighing it down. As for the latter, thicker, curlier hair types need all the nourishment they can get, so our experts recommend opting for more substantial heat protectants, like serums and creams, which will infuse the hair with moisture. hydration in addition to protecting strands from high temperatures.

Look at the formula.

Beyond the texture (spray, cream, serum, etc.), Blakely invites you to look at the ingredients listed on the label. “Certain ingredients are known to have natural heat-protective abilities,” she explains. If your heat protectant of choice contains any of the following, Blakely says your hair is in good hands.

• Silicones: These form a heat-resistant barrier, which helps protect hair from damage while improving its softness and shine.
• Hydrolyzed proteins: These strengthen the hair and provide a protective film to reduce heat damage.
• Aloe vera: It helps boost hydration and creates a layer that locks in moisture while providing light protection against heat.
• Grapeseed oil: Known for its high smoke point, it acts as a natural heat shield.
• Argan oil: This natural oil improves hydration, reduces frizz and helps protect hair from heat.

Think about when you will use it.

Do you dry your hair regularly or generally apply heat once your hair is dry? Some heat protectants only work on damp hair, while others can be sprayed on dry hair. Check the instructions before purchasing your protector of choice to ensure it will match your preferred styling method. (FYI, almost all sprays can be used on wet and dry hair!)
