How to Dye Synthetic Hair Extensions?

If you were looking for a cheaper way to add volume or length to your hair, you have probably bought synthetic extensions or a wig. It was all good in the beginning, but now you kind of got bored with it and want to dye it in order to revive it a little bit.

If you have ever tried to dye synthetic hairwith real hair dye you probably discovered that it doesn’t really work . Hair dye is made for real hair and not the synthetic fibers that some extensions and wigs are made out of. But there are a couple of ways to change the color of your synthetic hair and we’re going to go through them.

Keep in mind that whatever method or coloring technique you use, the synthetic hair has to be light colored in order to get good results. Since you can’t bleach synthetic hair, it has to just start off lighter than the color you want to dye it. This means that white, silver, blonde, and pastel colors will work the best.

Method #1: Acrylic Ink Dye

Method #1: Acrylic Ink Dye

Synthetic fibers can be dyed by using a combination of ink and alcohol. One of the best ways is by using acrylic ink and isopropyl alcohol. To get started, mix up your DIY synthetic hair dye. Pour the acrylic ink into the spray bottle and then add some rubbing alcohol. The amount of alcohol that you’ll want to use depends on how light you want the color to turn out. Use more alcohol to dilute the ink if you want a lighter, less opaque color or use less alcohol for a more vibrant, richer color.

Put on some gloves to keep your hands clean and then go ahead and apply the dye to the wig/extensions by just spraying it on. You can first spray it on in sections and then just dig your fingers all up in there to make sure the hair is saturated, not just on the top but on the underside too and that it is coated all the way through. Make sure you move the hair around as you go so you’re not just dying the top layer of hair. Start using a comb to brush the dye through to make sure you’re getting it on all of the hairs, all of the layers, front and back, roots and everything.

Method #2: Sharpies Dye

Method #2: Sharpies Dye

You can also make a similar ink combo by mixing rubbing alcohol with the ink from Sharpies which are alcohol based markers. For this method, you’ll need Sharpies, of course, rubbing alcohol, a spray bottle, pliers, a knife, and gloves.

Use the pliers to pull the Sharpie apart. Your goal is to get the ink tube out of the marker. So grab the colorful front section of the Sharpie with your pliers and wiggle it around and pull it until it all comes apart. This can take some practice! It can be hard at first, but you got this!

Once it’s apart, put the ink tube aside. Then use your pliers to remove the little tip from the front of the sharpie for a little bit of extra ink. This part should come out much easier. And then using something sharp, slice open the ink casing so the ink will come out easier.

Drop the ink tube into the spray bottle and add some alcohol. Then you just got to let it sit for a while. The longer you let it sit, the better. It is best to leave it overnight to get the most out of the ink casing.

Then you just apply it the same way as the acrylic ink mix, making sure the dye is applied everywhere.

Rinsing and Drying

Rinsing and Drying

Once you’re satisfied and think you’ve got it all covered, it is time to step back and let it air dry. If it’s fully saturated it’s probably going to drip everywhere so we definitely would recommend covering your workspace beforehand with trash bags, a plastic tablecloth, or newspaper. Save your table!

Give it at least an hour to dry, but sometimes it takes a little bit longer, depending on how thick and long the hair is. Once you can touch the wig and not get dye all over your hands, it’s probably dry!

Now that the synthetic hair is dry, you can rinse the dye out in cold water until it runs clear. Get all of that ink out of the hair so that it doesn’t transfer to your clothes later. Also, if you’re using a wig, make sure you rinse the cap out because while dying it you probably got some ink in there and you don’t want that transferring to your hair either.

After it’s all rinsed out, lay it out on a towel to dry. Since this is not real hair, it is not recommended that you blow dry it or use any hot tools on it since that can damage the synthetic fibers. After it dries, brush the hair thoroughly. And that’s it, your synthetic hair is ready to wear and you can show off your new color!


Although there are some methods for dying synthetic hair and making it look more natural and fresh, it will never replace real hair. Remy hair extensions and wigs look beautiful, feel nice, last for a very long time, and don’t get damaged easily. With synthetic hair, you will get tangling, matting, and it will quickly look worn out and damaged. It often looks fake and unnatural and many people will definitely notice it. You also have a lot less styling options and can’t use normal hair dyes. 100% remy human hair looks natural and is indistinguishable from your own hair. It is also much easier to maintain and take care of.

That’s why it’s really worth it to invest a few extra bucks and grab real extensions. You will definitely not regret it because the difference is huge and you will never get back to synthetic hair.
