The answer is Yes! It is possible to straighten your synthetic hair on low heat. But before jumping into straightening synthetic hair, there are some essential considerations that you should look into first.

Synthetic hair type

All the synthetic hair you can find in the market are very different from each other. They are made from different materials and with different formulations. Some synthetic hairs are very high quality and heat resistant whereas others are not. They are built with cheap materials such as colorful party wigs and are very prone to damage even on the lowest heating setting. So, you need to know the manufacturer, material, and quality of the synthetic hair first to determine if you can straighten your synthetic hair and the optimum temperature for that.

Optimum heat temperature

Maintaining the optimum heat is crucial while straightening your synthetic hair. Most of the synthetic hair types can be effectively straightened at around 250°F (120°C). Low heat helps to maintain the original texture and quality of your synthetic hair while reducing the possibility of damage. If you are using a heating tool, you need to make sure that you can monitor and control the heat. The temperature should never exceed 350 F (175 C) for any type of synthetic hair type because high heat can make your synthetic hair melt, frizzy, tangle, damage, and shorten its lifespan.

3 Considerations Before Straightening Your Hair

You should consider these factors before straightening your synthetic hair so that it remains safe from damage and can have a long lifespan.

  • Use a heat protectant: If you want to straighten your hair with a heat styling tool, you should use a heat protectant that is specifically made for synthetic hair extensions. By creating a barrier between the hair and the hat source, a heat protectant reduces the chance of getting the synthetic hair damaged directly.
  • Test a small section: If you are not able to monitor the temperature to straighten your synthetic hair, you can also do a section test first. Start with the lowest temperature that you can go for and notice how your synthetic hair responds. Take a small amount of hair from the back part of the wig to test. If with that temperature the hair is melting, damaging, or giving sizzling sounds, you need to stop right there.
  • Follow manufacturer’s guidelines: You should always consider the manufacturer’s guidelines first regarding the maximum temperature for that specific synthetic hair. They typically provide the information regarding the wig and whether that is heat resistant or not. Otherwise, you can just look for the material and search what is the maximum heat that the material can handle.

1. Hot Water

Hot water is one of the methods that will help you to straighten the hair and will also help to make your hair smooth. You can use this technique in both heat-resistant and any average synthetic hair. For this water method, first, you need to detangle the hair with the wig brush. Then, you have to boil water in a large pot at a temperature of 160°F to 180°F (70 ℃ to 80℃). To acquire enough water to cover the wig, try using a big pot depending on the hair length. Then you need to soak the whole wig in the pot for 10 to 15 seconds. After removing the synthetic hair from the water, place that in a wig stand. Secure that with the T-pins so that it can stay in place. Then blow dry the hair while constantly brushing the hair straight.

2. Flat Iron

Flat iron is a method that you should do only when you have heat-resistant synthetic hair. Especially when your hair straightener has an auto temperature setting and you do not know the actual temperature. If the temperature is high, it will have the chance to melt or burn your wig if that is not heat resistant. For straightening your synthetic hair with a flat iron, you need to set the wig in a mannequin head. Then, secure the wig with T-pins so that the wig does not slide off, and detangle the hair with a wig brush. After that, separate the hair into small sections, clip them off, and start straightening with the lowest heating setting. You can also use a heat protectant to keep your synthetic hair on a safer side.

For the steaming method, you will need to have a portable steamer. First, place your synthetic hair in the wig stand and brush out the hair. Then turn on the steamer and steam the hair from every direction until the whole hair is soft and easy to comb. You can also steam the hair and comb that in sections for easier application. Comb the hair in a downward motion until the hair becomes straight. Since steaming does not apply direct heat to the hair, there is no chance of burning or melting your synthetic hair. But you might need to repeat the procedure multiple times to make your synthetic hair completely straight. Next, let the synthetic hair air dry and apply some leave-in conditioner for a softer and shiner result.
