Your hair is dead. Although your hair seems to be alive by the mere fact that it grows, hair is nothing more than dead fiber.

Your hair doesn’t have any active cells once it emerges from the scalp.

As a result, your hair can only stay in its original condition as it emerges (with good maintenance) or deteriorate over time. The hair we see has no active cells within it capable of fixing any damage that takes place once it has emerged from the scalp.

As you add heat to your hair strands, it’s critical that you take the necessary precautions to ensure that you protect your curl pattern from the heat exposure of blow-drying, flat ironing, curling, and other forms of thermal styling.

In this article, we’ll be discussing how to protect your curls when you use heat styling tools, and we’ll highlight the best heat-protectant spray for natural hair.

Without further, let’s get started.

What’s the Best Heat Protectant for Natural Hair?

The best heat protectant for natural hair is the TRESemmé Thermal Creations Heat Tamer Protective Spray. It’s good for ladies that like to heat style their hair and are looking for ways to protect their hair from heat damage.

Using heat to create a silky smooth hair texture damages your hair physically. The physical damage is the result of direct exposure to heat (e.g., flat irons, blow dryers, etc.), which can cause your hair to become dry, brittle, and break.

This type of damage is often irreversible and can leave your hair looking dull, limp, and lifeless. The TRESemmé Thermal Creations heat tamer leave-in-spray is a heat protectant that helps to shield your hair from both types of damage.

Using heat on your hair can result in physically heat-damaged hair as well as irreversible changes to your hair at the molecular level.

The natural structure of keratin, the protein present in your hair, can be irreversibly changed by using high-temperature heating appliances or by exposing your hair to prolonged heat styling.

Keratin is thought to give your hair its natural twist, also known as the alpha helix. This natural twist is present in all types of hair.

When your hair is heated to a temperature around 215° to 235°C or 419° to 455°F, the alpha helix begins to melt. This results in an irreversible change in the hair. At the molecular level, the hair retains the shape of the melted alpha helix. 

At the physical level, the hair shows this molecular damage by failing to revert back to its original naturally curly shape. It’s important to note that all hair damage is cumulative, so it can build gradually over time as you continue to use heat styling techniques.

A good heat protectant, like this TRESemmé's leave-in spray, creates a protective barrier against heat appliances.

Gentle treatment and hair conditioners can prolong the life of damaged hair, but the hair is still damaged, and the damage will usually increase with time. This is why heat protectants are necessary if you plan to utilize heat styling.

What Are Heat Protectants?

Heat protectants are silicone formulations used to protect your natural hair from heat damage. Heat protectants are usually made up of hydrolyzed proteins, amino silicones as well as polyquats.

They work by forming a barrier on the hair shaft that prevents heat from penetrating the cortex of the hair. This, in turn, protects your hair from becoming dry, brittle, and breaking.

Do Heat Protectants for Natural Hair Really Work?

According to numerous research studies, heat protectants work pretty well when they’re used properly. Based on scientific research, heat protectants do the following:

  1. Mitigate the breakdown of hair proteins (J. Cosmet. Sci., 49, 245-256 Jul./Aug. 1998).
  2. Mitigate loss of water from the hair strands and reduce the hair cuticles from cracking the hair as well as allowing the hair to maintain its strength after heat treatment (J. Cosmet. Sci., 55, 13-27 Jan./Feb. 2004).

It’s important to note that hair generally isn’t damaged by low heat (less than 100°C) applied for short time periods of time. However, we know that 100°C isn’t exactly low heat, especially when you consider that water will boil at this temperature.

Do I Need a Heat Protectant on Natural Hair?

You should use a heat protectant anytime you’re using heat-styling tools such as curling irons, flat irons, and blow dryers. If you have damaged hair or are concerned about preventing future damage to your hair, using a heat protectant is a must. Applying heat to your hair without a heat protectant can result in physical damage to your hair as well as irreversible changes at the molecular level.

Does Heat Protectant Work on Natural Hair?

Yes, heat protectants work on natural hair. Heat protectants are silicone formulations used to protect your hair from heat damage. Heat protectants usually contain hydrolyzed proteins, amino silicones as well as polyquats. According to research, these ingredients help to mitigate the breakdown of hair proteins and reduce the amount of water lost from the hair strands.

How Do I Protect My Natural Hair From Heat Damage?

Routinely using a heat protectant is the best way to protect your hair from heat damage. A heat protectant can help to mitigate the breakdown of hair proteins and reduce the amount of water lost from the hair strands. Additionally, using low heat settings on your styling tools and avoiding extended periods of time with heated tools on your hair can also help to keep your hair from suffering heat damage.

When Does Heat Protectant Expire?

Heat protectants, on average, can stay on your hair for up to 4 hours after applying it to your hair. The effectiveness reduces quickly after roughly 4 hours. If you’re also wondering how long a container of heat protectant lasts before it goes bad, the average lifespan of a heat protectant is one year. Although, we always recommend reviewing the product packaging and following the expiration date provided by the manufacturer. Read this article to learn more about how heat protectants last.

Do Heat Protectant Sprays Actually Work?

Heat protectant sprays can be effective in reducing the amount of damage caused by styling tools.

They’re very important for healthy hair.

Is Heat Protectant Spray Good for Hair?

Do You Put Heat Protectant on Wet or Dry Hair?
