Straighten Synthetic Wigs with Steam

To use steam on your synthetic hair, all you need to do is take it to the bathroom. Lock all the doors and windows to trap heat as much as possible. Then put on the hot water in the bathroom, and leave it on until the bathroom is filled with steam.

Start brushing the hair from the tip using a wide-tooth comb. Make sure you brush gently and slowly to avoid damage due to breakage. 

The heat from the steam combined with the brushing will loosen the curls and make them more straight. Once it becomes straight, take it out of the bathroom and allow it to cool. With this method, you have not exposed the hair to too much heat; hence it has a lesser risk of damage.

You can also use a steamer for this method. You need to hold the steamer in one hand and a brush in the other hand. Brush through the hair and follow with the steamer.

But the steamer should not be too close to the wig to avoid damage. Once you have covered the whole area of the hair and it is completely straight, leave it to air dry. Then spray with hairspray.

Final Thoughts

Yes, you can flat iron your synthetic hair and straighten it with other methods. However, know that the risk of heat damage from synthetic hair is high. Hence, you should avoid using it.

You should buy a straight and curly wig if you want to switch up styles. This does not only save the synthetic hair from damage but also makes it last longer.
