The Importance of Heat Protectants for 4C Hair

Keeping a head of 4C hair healthy and looking its best requires a great deal of work, and this is why it is so essential to use hair protectant.

It works to mitigate the effect of styling tools such as blow dryers and curling hours, all of which are capable of damaging your hair.

If used in excess, heat will inevitably cause a great deal of damage to your hair—sometimes irreparable. Consequently, your hair can frizz or possibly even break off.

Moreover, curly hair is susceptible to dryness and split ends if not properly cared for. Hence the importance of using a heat protectant.

When it comes to 4C hair, hair protectant is even more essential due to the tight and kinky coils, meaning that your natural oils have difficulty traveling down each hair strand.

Remember to keep all of your heat on your styling tools lower than 450° F. Choosing to go higher will result in damage regardless of how strong your heat protectant is.

Choosing the Right Heat Protectant for 4C Hair

Your heat protectant can come in any texture, from creams to oils to serums or sprays. Here are some qualities you should be looking for when deciding on a heat protectant for 4C hair type.

Resistant to High Heat 

Always look for a heat protectant that protects your hair at the highest heat levels, 400º F or higher.

A thermal protector of this caliber will be able to protect your hair from the heat at a higher setting or if you’ve been using styling tools for a long time.

Draws in Moisture 

4C hair is a dry hair type because of the difficulty the curls and coils present for the natural oils when attempting to travel down the strands. Consequently, you need to ensure that the product you choose locks in moisture and protects your hair.

Your protectant should have propylene glycol and glycerin. These ingredients will actively protect your hair from heat damage.


You want to find a heat protectant spray capable of sealing in the cuticles of your hair while simultaneously disallowing outside moisture to affect your hair.

This quality will ensure that your hair is frizz-free and full of moisture without compromising the style. This is important since 4C tends to shrink easily.

Adds Shine 

If you are using a heat protectant to straighten your hair, then look for a one that supplies your hair with a high gloss finish. You can achieve that by using other products in conjunction with your heat protectant. However, it always helps if your heat protectant already has this property.

How To Protect 4C Hair From Heat Damage

Here are the steps to follow if you’re going to use heat tools on your hair, but you want to minimize the damage: 

  1. Regular Deep Conditioning: This will prime your hair to be ready to withstand any heat by ensuring that it is healthy and moisturized.

  1. Detangle: Begin by putting your damp wet hair into four sections. This helps you to remove snags and knots before you proceed with styling your hair. This step is necessary because it keeps you from using more heat on your hair than is required due to tangles.

  1. Use a Heat Protectant: If you have natural or curly hair and you’re trying to apply heat to your hair, prepare your hair by using a heat protectant first. Your heat protectant should be able to protect your hair up to 450° F which is the case for most protectants.

  1. Use Low Heat: When styling naturally curly hair, you have to use minimal heat. However, some areas of your hair will need more heat than others, which is fine. Just refrain from raising your heat above 350° F to maintain healthy hair.


Here are the answers to the most commonly asked questions about heat protectants:

Is shea butter a good heat protectant for 4C hair?

Yes. Shea butter is a popular ingredient in many heat protectants for 4C hair because it is very moisturizing and an awesome heat conductor.

Using a styling tool on too high of a temperature setting could result in the shea butter burning your hair.

You can decrease this by adding moisturizer or lightweight leave-in conditioner to your hair before applying the Shea butter.

Are products with coconut oil good heat protectants for natural hair?

It is very beneficial to use oil on natural hair.

Coconut oil is very moisturizing, which is why it is present in many hair care products. But, coconut oil can be too dense for some hair types leaving behind limp locks.

It is a better idea to mix coconut oil with grapeseed oil. Make sure that the oils you select have a high smoke point if you use them as heat protectants.

Can the leave-in conditioner be used as a heat protectant?

It depends – you have to ensure that your leave-in conditioner will protect your hair from heat. Below you’ll find common ingredients in leave-in conditioner capable of protecting your hair from heat:

  • Shea butter – Known for protecting natural hair from heat.

  • Almond oil – Possesses a smoke point of 430° F which is high.

  • Coconut oil – Capable of protecting your hair up to 450° F.

  • Avocado oil – The smoke point is very high at 520° F

Remember that specific smoothing agents and proteins can protect your hair. Just check the label for good ingredients, and if they are present, you should be able to use the leave-in conditioner to protect hair from heat. 

What are the best heat protectants for a silk press?

You’ll want to choose an option that contains silk proteins, as they will make the hair softer and smoother in preparation for getting your hair flat-ironed. 

The CHI 44 Iron Guard Thermal Protection Spray is an excellent decision, as well as the Olaplex No. 7 Bonding Oil or the Cantu Thermal Heat Protectant Spray. 

The last two don’t have silk proteins, but they are lightweight and make the hair smoother, which aids in getting a sleek finish from the silk press.

How We Researched & Tested

Research involves personal experience, scouring the internet for reviews from those who have 4C hair and can attest to their experiences, and understanding the ingredients in a heat protectant. 

You always want to read the label with any product you select to understand whether you’re genuinely protecting your hair and adding moisture. 

We tested the products against various tools such as a blow dryer, curling iron, flat iron, curling wand, and any other heat tool. We checked for any loss of elasticity, curl definition, and dryness after using the heat protectant. 

These barometers are key signs that your hair has suffered damage, and as such, once you proceed to rewash your hair after heat styling, it’s apparent whether your hair is weak if your curls are limper, your hair seems dull, and the hallmark of 4C hair (shrinkage) is non-existent. 


Remembering to distribute a quality heat protectant throughout 4C hair evenly is crucial to maintaining its vitality. A suitable product will protect your strands and moisturize them and keep them strong when exposed to high temperatures. 

The Shea Moisture Anti-Breakage Spray gives you everything you need to prevent heat damage. It coats the hair, decreases hair breakage by 70 percent, is lightweight, and contains natural ingredients that are intrinsically good for hair health. 

While every choice on the list is an excellent addition to your hair care arsenal, I highly suggest grabbing the Anti-Breakage Spray if you want to get the best heat protectant for 4C hair.
