We get it—sometimes reaching for a heat protectant isn't top of mind, especially when you're rushing to get ready for the day. But just like flossing before brushing, using a base coat before painting your nails, and lining your lips before topping them with Pillow Talk, applying a heat protectant before heat styling is essential. With no barrier between your hair and a temperature that's literally hot enough to bake a cake, you're setting yourself up for tons of damage in the form of breakage, dryness, dullness, and brittleness—all of which can be tough to reverse.
Fortunately, there are plenty of options on the market when it comes to heat protectants, whether you're one for big, bouncy curls or an at-home blowout, and whether you're working with hair that's fine and frizz-prone or thick and coarse. What's more is that many of them have additional benefits way beyond protection from high temps—think detangling, moisturizing, and boosting softness, shine, and manageability.
Now that we've convinced you, take a peek at the list below. We rounded up a list of the Top 10 heat protectants on the web, featuring a reviewer-favorite formula for every hair type, concern, and budget.
