Best Heat Protectant Sprays for Straightening Your Hair

If you’re living in this day and age, you’re probably using heat styling tools to straighten your hair on occasion—and why wouldn’t you? There is an incredible array of styling tools on the market, and they all offer pretty impressive results from the comfort of our home. The only downside is the ever-present threat of heat damage—but you can work through it with a good heat protectant spray.

Today we’re taking a deep dive into the hows and whys of these miracle products. How do heat protectants they work? (Actually, do they even work?) Why should you be using them? And how should you apply them to achieve the best possible results? Let’s find out!

Your intro to heat protectant sprays

Let’s start with the basics: heat protectant sprays are leave-in sprays that are specifically designed to protect your hair from heat damage. No only do they protect your hair, these products also help smooth down the hair shaft (which increases shine), reduce frizz, and improve manageability.

So, do heat protectant sprays actually work?

Heat protectant sprays work by creating a thin film or veil between your hair and the heat styling tool of your choice. This film makes the hair heat up more slowly and more evenly, which helps reduce damage.

So, on one hand, yes, heat protectant sprays do work. On the other hand, it’s never that simple. Studies suggest that heat protectant sprays might only protect against 50% of the heat generated by styling tools. Depending on your perspective, this may be a little or a lot.

If you’re someone who uses heat styling tools every day, every little bit of protection helps. Likewise, if you use your tools at very high settings, your hair can use all the help it can get. Just keep in mind that most heat protectants are designed to protect hair from temperatures up to 220ºC or 230º.

Do heat protectants really reduce frizz?

Heat protectant sprays can help reduce frizz by forming a barrier between your hair and the outside world. While this barrier is designed first and foremost to protect against heat damage, it also serves the handy purpose of sealing in moisture and smoothing down the cuticles of the hair shaft, which helps reduce frizz.

Do you put heat protectant spray on wet or dry hair?

Heat protect sprays can be applied to both damp and dry hair. Different formulas will come with different recommendations, so make sure to check whether the product you’re using is suitable for either use.

If you’re working with truly wet, soaked, straight-out-of-the-shower hair, make sure to towel dry it before applying your heat protectant spray. Then, proceed to blow dry your hair as you normally would. As for flat irons and curling irons, you should never use them on wet hair, as this can cause quite a bit of damage. Did you know that, when exposed to high heat, the moisture inside your hair fiber evaporates rapidly, essentially bursting through the outer surface of your hair? Yeah. Let’s avoid that whenever possible!

Should you let your heat protectant dry before straightening?

When applying heat protectant to your hair, you should let it dry for a little bit—anywhere from a few minutes to a few hours, depending on how much time you have available.

In the ideal scenario, you’d apply your heat protectant spray, go about your life, and then come to use your heat styling tool once your hair had fully dried. This may not be realistic for you, but try to adjust your routine so you get a few more minutes between the application of the product and the actual heat styling.

Can you use heat protectant every day?

You should use a heat protecting spray every time you use heat styling tools. If that’s every day, then by all means, use your heat protectant every day. You’ll be protecting your hair against heat damage, and you might just get a few extra conditioning benefits while you’re at it.

Indeed, many heat protectant sprays are formulated with conditioning ingredients that soften the hair in order to create a smooth, shiny surface. We’ll show you some of those below.
