Heat Protectant: Why It’s So Important

Straightening irons, blowouts and curls, oh my! They are wonderful tools that have become part of our daily hair routines, yet they can leave it feeling brittle and dead. But, fear not! That’s only when your hair isn’t protected. Heat protectant has been around for many, many years, and for a good reason too. It’s important to protect your hair against damage caused by hot tools. Protectants help keep your hair healthy by locking in moisture to the cuticle and helping prevent it from breakage and frizz.

What is Heat Protectant?

We like to think of heat protectant as a form of sunscreen for our hair. Heat protectant is a product used prior to styling that is specifically designed to create a barrier between the hair cuticle and a hot tool to reduce damage. They come in many forms, but most often in a spray, cream or serum.

When Do I Use Heat Protectant?

The best time to use heat protectant is after you wash your hair and before you blow it dry or use any heat appliances. You should always use a heat protectant before you style, even if it is already dry to protect it from becoming damaged. The best defense against dry, damaged hair is to use a high-quality shampoo that is designed to repair the hair and provide strength and shine from the inside out. Our Evolve line was formulated for this specific reason. To help repair your hair and strengthen those damaged ends, we suggest starting on Evolve now. For more information on that line, click here.

Pro Tip: If you have colored hair, using a heat protectant and color-safe hair repair shampoo like Evolve is even more important so that your color lasts longer. High temperatures are known to oxidize hair color faster, leaving your freshly colored locks fading and brassiness due to underlying pigments.

How Damaged Is My Hair?

Heat protectant acts as a barrier between your hair and the hot tools we often use to style our hair. It seals in moisture to the cuticle so that hair doesn’t become frizzy and damaged. If you haven’t been using a heat protectant or not using a strong enough formula, chances are you’re seeing some degree of heat damage. The best way to test the quality of your heat protectant is by doing a little experiment…

How To Test Your Heat Protectant

1     Spray your current heat protectant product on the back of one of your hands. Leave the other bare.

2     Grab your hair dryer and the hand without the protectant. Take note of how quickly your hand heats up. Use a medium setting to avoid burning your skin.

3     Now use the hair dryer on the hand that has been sprayed with the heat protectant and take note.

4     Did you notice a difference in how quickly the heat penetrated your skin?

Your hand will still get hot, but there should be a noticeable difference between the hand that was sprayed with the product and the hand that wasn’t (found this little trick from a Thomas in Action Blog). If you didn’t notice a change, we would suggest investing in a higher-quality heat protectant or doubling up on products. More on that below.


What Can I Do To Keep My Hair Healthy?

If you’re like us, we love to have our hair always looking fabulous, but the health of our hair is even more important. So, we compiled a list of tips that help keep your hair healthy and stylish.

Don’t Use Heat Tools Every Day

Using styling heat tools on your hair too often can cause it to break faster, so we always recommend to try and cut back on how often you are styling your hair with heat. Every other day is a great place to start.

Let Your Hair Air Dry

Any time that you are able to take your time getting ready, try to let your hair air dry. Just forgoing the blowdryer can preserve the health and life of your hair. Even if you can’t let it air dry all the way, always try to let your hair dry at least halfway before starting a blowout.

Always Use a Heat Protectant

Although Zenagen’s Boost line doesn’t have a product specifically designed as a heat protectant, we do have our Densifying Leave-In Cream that has heat protectant properties. It is used as an added shield against heat and sun’s damaging rays, plus it acts as a primer for a killer blowout. However, we do suggest pairing with our Evolve line and a heat protectant of your choice for optimal protection.

Avoid Chlorine Water

With summer right around the corner, try to avoid chlorine water, as it will dry your hair out. If you are going for a swim, throw some conditioner in your hair before you dive in for added protection! Check out our Say Goodbye to Split Ends Blog for more ways on protecting your hair.

Keep Your Styling Tools Below 300

 If you have fine and thin hair, remember to always keep your tools below 300 degrees. Fine hair is more prone to burning quickly. You don’t want to end up like this girl…



It’s no surprise heat protectant is so important to protect your hair. With continued use of hot tools on non-protected hair, they can wreak havoc on your beautifully styled hair. Our mantra for this blog post is this: Hair is only as beautiful as it’s health. So protect that gorgeous head of yours… it will thank you for it!
