Can Synthetic Hair Be Bleached?

It’s not advisable to bleach synthetic hair because they are made from materials like polyester, nylon, plastic, etc., and don’t react to bleach and dyes in the same way as natural hair.

If you bleach synthetic hair, it will likely destroy their material and texture, shorten their life, damage them beyond repair, or render them unusable.

The reason bleach negatively affects synthetic hair is that they are made from artificial strands featuring plastic materials that tend to react poorly to strong chemicals found in bleach.


How Do You Lighten a Synthetic Hair?

You cannot use bleach to lighten synthetic hair as you can with natural hair. Using bleach or even regular hair dye is very risky as your synthetic hair will dry, get damaged, or break off. The good news is, there are some alternative methods to lighten synthetic hair.

The most popular method to lighten synthetic hair is using Sharpie markers. Follow these instructions:

  1. Bend three markers to break them in half and use a knife to slit the ink sticks. Then empty the ink into a spray bottle.
  2. Next, pour a cup of alcohol into the spray bottle and shake it to get the desired color. Add more alcohol to make it lighter.
  3. Now spray your synthetic hair and then let them dry for a few hours.
  4. Finally, rinse the hair in cold water to get rid of the excessive ink. Then let it dry.

Can Synthetic Hair Be Highlighted?

The short answer is no. Unless they are made with real human hair, synthetic hair cannot be highlighted. The reason is simple: the materials they are made of reacting poorly to chemicals included in bleach and dyes.

If you try to highlight them via bleach or dyes, the hair will start to deteriorate and over time, you will end up with uneven color or even fried broken off hair.

That said, one method exists to highlight synthetic hair. It involves using acrylic paint to add highlights to hair. However, it is time-consuming and the results you get by using this method are inconsistent.


Can Synthetic Hair Be Dyed?

Technically, you can dye synthetic hair but it’s generally not recommended. This is because regular dyes don’t work well for synthetic hair and while acrylic paint is a good option as it doesn’t damage the fibers of synthetic hair, its results tend to be inconsistent.

Synthetic hair can be dyed from industrial perspectives. Different coloring creams must be used for best results but it is something that isn’t available on the market to average customers. If you use normal tints to dye the synthetic hair, you will end up permanently ruining them.


Can Synthetic Hair Be Curled?

Yes, but only if the synthetic hair is made with heat-friendly fibers. Curling traditional synthetic hair is not possible because any heat sources e.g. curling irons, hair dryers, etc. will damage or even melt the hair.

On the other hand, if your synthetic hair has heat-resistant properties, then you can curl and style them however you want. Still, it is recommended that you proceed with caution as most synthetic hair only allows for mild heat to be used.

There are alternate ways to curl synthetic hair without heat. It is highly recommended that you use them. These include using bendy rollers, headband wrapping, and plaiting the hair.


Can You Dye a Synthetic Wig with Regular Hair Dye?

No, synthetic wigs cannot be dyed with regular hair dyes because their fibers aren’t penetrable like natural hair fibers. Not to mention if you use regular dye on a synthetic wig, the chemicals in the dye will severely damage the hair fibers.

The good news is, there are special dyes available on the market that have been specifically designed for synthetic wigs. They are suitable for pretty much any synthetic fibers.

When using them, make sure to use hot water for the best results. Apart from this, there is a fabric dye that also works well on synthetic wigs. It is called Rit dye. However, using it can be quite messy and the results aren’t always the best.


Can You Use Temporary Hair Dye on Synthetic Hair?

Yes, you can but it is generally not a good idea. This is because even though the hair dye is temporary, it is still too harsh for synthetic hair fibers and will damage them. It may not permanently ruin or destroy the synthetic fibers but it will not provide the results that you expect either.

It is likely that the temporary hair dye will not stay on synthetic hair. It may even make the synthetic hair feel kind of stiff and gummy.

Not to mention there aren’t many color options available when it comes to temporary dyes. So, it is generally better to just buy new synthetic hair that features your favorite color instead.


Can You Color Synthetic Braiding Hair?

Yes. It is actually a very straightforward process. Regular dyes will not work so you will need to use acrylic ink. The process involves basically two steps:

  1. Get acrylic ink, rubbing alcohol, and a spray bottle.
  2. Use your preferred method to color synthetic braiding hair, e.g. dipping braids in color, spraying, etc.

Keep in mind that you will not get good results if your synthetic braiding hair is dark-colored. This is because it’s only possible to darken synthetic hair. Since you cannot bleach synthetic hair fibers, it’s better to start off lighter as opposed to the color you wish to dye it.

Colors such as pastel, blonde, silver, and white will work best. If you would like vibrant and bold colors, you should start with white, gray, or bleach blonde synthetic braiding hair.


In summary, Synthetic hair is made of man-made fibers that are very similar to real hair in thickness and texture, although synthetic hair tends to be shinier and more durable. This type of hair also shimmers, while human hair has a dull appearance and matte luster when light shines through.

Synthetic hair is amazing stuff. It looks and feels like real hair, usually comes in a variety of colors and styles, and lasts a really long time. However, there are things you can’t do with synthetic hair that you can do with real hair.

For example, it’s difficult to dye synthetic hair; the wig or extensions look very different after dying. Another thing: basically every expert says not to use regular hair dye on synthetic hair.
