There are a lot of wigs on the market that claim to be synthetic or heat-resistant hair. But, not all of them live up to their claims. To help you avoid buying a wig that won’t last, here is how to tell if a wig is heat resistant or synthetic.

However, before we dive into that, Let’s briefly look into the difference between synthetic and heat-resistant wigs so as to prevent ambiguousness when we are explaining how to identify which of the two your wig is.

Difference Between Synthetic and Heat Resistant Wig

Heat-resistant hair is made from synthetic fiber that has been treated with a chemical process called “keratinization.” This treatment protects it from getting damaged by heat and sunlight, which means it can be styled with hot irons and flat irons without damaging the wig’s structure or causing any damage to your natural hair.

It is made from a material that can withstand high temperatures. It can withstand heat up to 350 degrees Fahrenheit and still look great when you take it off.

This type of wig will not lose its shape or color when exposed to higher temperatures. It is perfect for ladies who have curly hair but do not want to use high heat on their own hair every day.

Synthetic or Heat Resistant Wig?

Synthetic hair is made from polyester fibers that have been processed into a strand shape. It has a different texture than the heat-resistant wig because it does not have thickness or fullness like the heat-resistant wigs do.

Synthetic wigs are less expensive than real human hair because they’re cheaper to produce. They also tend to be easier for people who have allergies or sensitivities to human hair products.

How To Identify If Your Wig Is Synthetic or Heat Resistant

If you have ever had difficulties in identifying which of the two your wig is, then the following three tips will be helpful:

1. Check the product description or tag

It’s important to check the product description or tag of any wig you buy to determine if it’s synthetic or human hair. If it doesn’t say anything about being heat resistant, then you should assume that it isn’t since most products don’t list this information unless it’s relevant to the product itself.

Wigs that are made from heat-resistant fibers are usually labeled as such. The tag will usually say something like: “Made from 100% heat-resistant fibers.” This means that you can use your normal curling iron, flat iron, or blow dryer on it without damaging it.

2. You can perceive the smell

The smell of your wig is another best way to tell if it’s synthetic or human hair. Human hair wigs will have a slight smell of chemicals, but it shouldn’t be overpowering. Synthetic wigs may have a stronger smell, so you’ll have to take that into consideration.

In short, A synthetic wig will have an odor like acrylic paint or plastic, while human hair wigs have no smell at all.

3. Check the wig’s appearance

The appearance of the wig is the first thing that you should check. If the wig is synthetic, it will look shiny and plastic-like. However, if it’s made of heat-resistant material, it will have a more natural look and feel.

Not only that, you can determine whether a wig is synthetic or human hair by examining the ends of the strands and feeling them with your hands. Human hair wigs are usually made from either Indian or Chinese hair. Indian hair tends to be darker, straight, and silky; Chinese hair tends to be lighter and curly.

Can Synthetic Wigs Be Heat Resistant?

Yes, Synthetic wigs can be heat resistant, but you have to make sure that they are made from high-quality material and that they have been treated with a heat-coating or some other special treatment that makes them more durable when exposed to high temperatures.

You should also look for synthetic wigs that have been designed with a thin layer of padding inside them so that they do not get damaged or melt when exposed to scorching temperatures.

What Happens If You Use Flat Iron On Synthetic Wigs?

When you flat iron a synthetic wig, it will start to drip and melt as soon as you begin to use the flat iron. Synthetic wigs are made out of materials like polyester and silk. These materials can be melted with heat, but they do not burn. They just melt down into a gooey mess.

You will need to keep an eye on it so that you don’t accidentally burn the wig by leaving it in too long or getting too close to the heat source. Once you’ve managed to get the wig straightened out, it may look good for a while before it starts melting again.

This is because synthetic wigs have been treated with chemicals that keep them stiffer than a natural human hair.

What Temperature Can Synthetic Hair Take?

Synthetic hair can be heated up to a maximum temperature of 320 degrees. However, the ideal temperature for synthetic hair ranges from 150- 320 degrees Celsius.

The reason why this is the recommended temperature range is that below 320 degrees Celsius, the hair will not be able to maintain its shape as well as it would when it’s at or above 320 degrees Celsius. This means that you will have to have more heat applied over a longer period of time in order for the style to take hold properly.

If the temperature is too high, then the hair might begin to melt or burn. This can cause damage to the wig and could even make it unusable.

How Do You Take Care of a Heat-Resistant Synthetic Wig?

Heat-resistant synthetic wigs are very easy to maintain but there are some basic things we recommend for taking care of them.

1. Apply a heat protectant spray to damp hair before using heat tools

It is pivotal that you should always use a heat protector before using a flat iron or curling iron. This will help prevent damage to your wig. We recommend using a silicone spray or heat protector spray.

3. Use wig spray regularly

Once you have completed styling your wig, use a shine spray on the ends of your hair to help keep it looking healthy and shiny. This will help in increasing the wig’s lifespan more than it would have been without a spray.

3. Excessive heat is bad for them

You should always start with the lowest setting on your flat iron or curling iron and work your way up from there. You want to make sure that it is not too hot for your synthetic hair because it can cause damage.

Also, remember that heat-resistant wigs can be damaged by heat, so make sure not to go above 320 degrees Fahrenheit when styling your wig.

4. Use shampoo made for synthetic

You can wash synthetic wigs if they get dirty or look dull. Wash them in cool water with a shampoo that’s recommended for synthetic wigs.

Rinse thoroughly and let them air dry on their own. If you want to put them in braids or curls before washing, make sure to loosen them up first by combing through them with your fingers or comb.


For emphasis, you can know if your wig is heat resistant or synthetic by checking the label and perceiving the smell, synthetic wigs smell more of chemicals than the hat resistant, and also, and the appearance and texture are good indicators.
