Top 5 Best Heat Protectant Sprays

If you use any type of heat styling tool on your hair—whether it’s a hair dryer, curling iron, or straightener—a heat protectant is a must-have.

Exposing your hair to any type of heat without applying a protectant first is like laying out in the sun without any sunscreen. Without a properly applied protectant, the heat will dry out your hair, making it brittle and prone to breakage.

To find the heat protectant that’s best suited to your hair type, there are a few things you should consider. The most important factor is your hair type and texture.

If you have fine or frizz-prone hair, you’ll want a protectant that will smooth flyaways without weighing down your strands. If you have hair that is already prone to damage, look for a protectant that provides maximum protection of up to 450 degrees Fahrenheit. If you have thick hair, a protectant that can be applied to wet hair is ideal so it can soak up all the product.

Knowing how you want to style your hair can also help you decide which heat protectant will best serve you. Heat protection should be applied at the very beginning of your styling routine while hair is damp.

If you just plan on blow drying your hair, a conditioning protection mist may be all you need. If you plan on using a hair straightener, using a protectant that will help smooth your hair and create shine will make styling easier. For wavy or curly styles, a protectant that provides texture, volume, and hold can help you achieve curls that won’t go limp after a couple of hours.
