Best Heat Protectant for Straightening Natural Black Hair – Top Heat Protectants for African American Hair in 2020

Styling Natural hair is not an easy task. This is even more of a challenge when it comes to black hair. Black hair is thick, coarse, and usually very large in volume and curly. Styling or taming such hair is delicate; hence the reason why most women turn to relaxers and strengtheners.

However, chemically processing hair has proven to cause more damage than good when done over a long period. Chemical relaxers and perms also permanently alter the nature of the hair, making it prone to damage and breakage. For this reason, women all over the globe have found that natural ways of straightening the hair and styling are better than the latter.

Such natural methods include using a flat iron, blow dry, and other heat-related methods. However, constant styling using heat can also cause damage to your hair. Heat can make the hair dry because it sucks the moisture out of the hair, making it look dull and brittle.

How can this be prevented?

One of the best ways to prevent hair damage caused by heat is by using heat protectants. Heat protectants are thermal products that are infused with ingredients like Shea butter, Jamaican black castor oil, extracts from the algae plant and mongongo oil which smoothen and protect the hair strands from any form of heat.

How exactly does heat damage natural hair?

Heat can cause a variety of damage on the hair, depending on the type of method. When it comes to blowing drying, a sudden burst of heat is produced. The temperature instantly dries up all the moisture.

This, in turn makes affects the cuticles of the hair by making them very brittle and prone to breakage. The hair cuticles are the parts of the hair that are responsible for protecting and strengthening the hair.

Straightening, on the other hand, affects the hair differently. When you apply the heat directly onto damp hair, it causes little explosions of steam that crack the cuticles of the hair. If you were to place the hair under a microscope, you would see that the cuticles have developed small holes and breaks.

Additionally, with time, using heat as a styling tool regularly can also affect the keratin proteins of the hair. Keratin proteins are the parts of the hair that make hair elastic and control the color pigmentation of the hair. Damage to keratin proteins results in less bouncy and thinner hair.

If you have colored hair, damage of the keratin proteins will also result in the color of the hair looking dull and brassy.

On top of that, damaged hair feels rough, limps and suffers from split ends, making it very difficult to style. It also becomes limb even after blow drying and is prone to fizziness and tangling.

How do Heat Protectants Work?

So far, using heat protectants is the only method that has been proven to protect hair from heat-related damage. Therefore, it is crucial that before instilling any form of heat to your hair, you use a heat protector. What happens is that these products are rich in ingredients that shield the hair from the adverse effects of heat.

Heat protectants work in the following ways:

Making the hair more porous

When hair is porous, it means that the hair can hold more moisture. When hair is damaged, one of the challenges is that it is unable to retain moisture. Therefore, heat protectants meant for natural hair contain healing elements that can restore the hair to its normal levels of porosity.

Adding moisture to your hair

One of the effects of heat on hair is that it strips the hair of its moisture. With heat protectants, you can be able to compensate for the moisture loss by restoring the hairs natural moisture levels. With the restored amounts of humidity, the hair becomes softer and more comfortable to comb through and remove tangles.  

Sealing and shielding the hair

What happens when you use heat protectants is that they form an additional layer that shields the hair against any form of heat. Heat protectants create a coat on the follicles of the hair that acts as a shield and prevents moisture from evaporating from the hair. This coat also protects the cuticles of the hair from other forms of damage from external sources.

What to look for in the best protectants for black hair

There are several different brands of hair protectants is the market that is all advertised as perfect protection against heat. However, not all advertising is accurate. Therefore, to make the right choice when choosing which product to purchase, you need a vast knowledge of the ingredients that make the best heat protectant for black hair.

Such ingredients include:

Heavy duty-moisturizers– the ingredients that have moisturizing elements include the likes of Shea butter, coconut butter and other plant extracts like grape seed oil, argan oil, and avocado oil. These products can give your hair a natural dose of moisture and nutrients that keep it perfectly healthy and moisturized.

Dimethicone– this is an FDA approved chemical that is used to make hair easier to comb through and style. This product is especially important to hair that has already suffered the damage of heat, making it rough, brittle and so tangled that combing through may result in further damage. This chemical softens the hair and detangles the hair making it’s less prone to further damage.

Clear silicone– this is also an FDA approved ingredient that is used to make the hair softer and gives it a smooth feel. It is also a product that is used to encourage fast penetration of nutrients into the cuticles of the hair allowing for the hair to heal from inside out.

Conditioners– good natural hair heat protectants are also packed with deep conditioning elements. Such elements soften the hair making it easier to style and comb through hence preventing further hair damage. They also strengthen the hair and hydrate the hair.

Avoid products with chemical elements like sulfates– such chemicals have been known to cause more damage than good to the hair. They slow down the hair’s natural ability to absorb and maintain moisture leading to dryness and brittleness of the hair.

Other ways of protecting your black hair from damage

Other means of maintaining and protecting hair include using the right kind of towel and combs and brushes. Wooden combs and brushes are the best to use since they do not cause static when combing hence do not harm the hair. Cotton towels are also preferable as they are not rough on the hair.

It is also crucial that you keep off hairstyles that can harm the hair. Hairstyles like high ponytails and tight braids can cause hair breakage and weaken the strands of the hair.

Proper hair maintenance involves regular shampooing with the right kind of shampoo, conditioning, and moisturizing and using lotion on your hair.
