Can You Dye Synthetic Hair Extensions? A Comprehensive Guide

Synthetic hair extensions have become increasingly popular in recent years as an affordable and easy way to change up your hairstyle. Many people opt for synthetic extensions over human hair because they hold curls better, are more affordable, and require less maintenance.

However, one downside to synthetic extensions is that you cannot dye them using traditional hair dye. This is because the materials synthetic hair is made from do not absorb hair dye in the same way human hair does. But don’t worry – while you can’t use regular hair dye on synthetic extensions, there are still several methods you can use to successfully dye them.

• Why you can’t use regular hair dye
• Special dyes and techniques that work for synthetic hair
• Step-by-step instructions for dyeing synthetic extensions

What Are Synthetic Hair Extensions Made Of?

Synthetic hair extensions are composed of synthetic fibers that are designed to replicate the look and feel of real human hair. The most common materials used to make synthetic hair extensions include:

• Kanekalon – The most popular fiber used for synthetic extensions. Kanekalon is an extremely versatile fiber that can be styled with heat tools.

• Modacrylic – A synthetic fiber that contains acrylic polymers. It provides a smooth, silky texture.

• Toyokalon – Similar to kanekalon but shinier and softer. It provides a very natural look.

• Thermoplastic – Synthetic fibers made from plastic polymers that allow the hair to be styled with heat tools.

Unlike real human hair, the fibers that make up synthetic hair extensions are uniform in size and shape. They do not contain natural cuticles, so they reflect light differently than real hair.

While high-quality synthetic extensions may look very realistic, they do have some differences when examined closely. They tend to feel slightly stiff, springy, and shiny compared to human hair.

Why You Can’t Use Regular Hair Dye on Synthetic Hair

The reason regular hair dye doesn’t work on synthetic hair extensions is because the dye cannot penetrate the synthetic fibers. hair has a porous cuticle layer that allows dye to be deposited inside the hair shaft. This allows the color to take hold and remain vivid even after washing.

Synthetic fibers do not have this cuticle layer – they are made of plastic, after all! With no cuticle layer, the dye has nowhere to bind to. It just sits on top of the synthetic fiber and eventually washes out.

Using traditional hair dye on synthetic extensions will result in splotchy, uneven color that quickly fades. It can even damage the synthetic fibers by drying them out.

Special Dyes & Techniques That Work on Synthetic Hair

While traditional hair dyes are a no-go, there are specially formulated dyes made for use on synthetic hair. Here are the most common options:

Fabric Dye

One of the most popular options for dyeing synthetic hair is regular old fabric dye, like Rit Dye. This dye is designed specifically for use on fabrics like polyester, nylon, and acrylic – the same materials used to make synthetic hair.

To use fabric dye on extensions, you’ll need to simmer the hair in heated dye according to the product instructions. The heat helps open up the synthetic cuticle layer so the dye can take hold.

Rit Dye is readily available at most craft stores. For the best results, choose their dye specifically formulated for synthetics.

Temporary Hair Color Spray

There are temporary hair color sprays made especially for synthetic hair on the market. Brands like Raquel Welch and Blow Pro make synthetic hair coloring sprays in a range of fashion colors.

These sprays create a thin stain on the outer layer of the extensions that washes out over time. They won’t permanently alter the synthetic hair.

Color sprays allow you to quickly and easily change up your look without damage. However, they don’t last as long as dyeing with fabric dye.

Permanent Marker

This DIY option involves coloring the extensions using permanent marker ink. It works best on lighter synthetic shades like blonde or platinum.

You’ll need to dismantle the markers and empty the ink into a spray bottle diluted with alcohol. Spray the mixture onto your extensions for a vibrant, semi-permanent result.

There are lots of great tutorials online that demonstrate the permanent marker method. It’s inexpensive but time-consuming.

Acrylic Paint

For a fun ombre or vivid color, give acrylic paint a try! Dilute acrylic paint with rubbing alcohol and apply to extensions with a tinted spray. Vibrant colors show up beautifully against darker shades.

Acrylic paint should fully coat each strand for an even application. Let dry fully before rinsing. Seal with a hairspray afterwards to make the color last longer.

How to Dye Synthetic Hair Extensions

If you want to permanently alter the color of your synthetic extensions, dyeing with a product like Rit Dye is your best bet. Here is a step-by-step guide to the process:

What You’ll Need

• Synthetic hair extensions
• Fabric dye (Rit DyeMore recommended)
• Large pot
• Measuring cups
• Metal tongs or spoon
• Old shirt & gloves for dyeing

Mix the Dye

Mix the dye solution according to the product instructions. You’ll need roughly 3 tablespoons of dye for every 1 cup of water.

Bring the water to a simmer on the stove. Add in the dye and stir continuously until fully dissolved.

Dye the Hair

Wet your extensions with warm water to open the cuticle layer. Use the metal tongs to submerge the extensions in the dye bath.

Keep the water at a low simmer – do NOT boil! Agitate the extensions lightly to ensure even coverage.

Let sit for 15-20 minutes, checking frequently to prevent overprocessing. For darker shades, allow the extensions to soak longer.

Use tongs to remove the extensions from the dye bath and rinse until the water runs clear.

Post-Dye Care

Give your newly dyed extensions a final rinse in cool water to close the cuticles and lock in color. Allow to air dry fully before wearing.

Be sure to deep condition and use sulfate-free shampoo to maintain the vivid color of your dyed synthetic extensions. Avoid applying additional heat from hot tools.

And that’s it! With a little bit of patience your synthetic extensions will be gorgeously dyed.

Pros & Cons of Dyeing Synthetic Hair Extensions

Dyeing synthetic extensions allows you to dramatically change your look for less money than buying new extensions in every color. But is it right for you? Here are some key pros and cons to consider:

Pros

• More affordable than constantly buying new extensions
• Can achieve fashion hair colors not found naturally
• Color won’t fade out of human hair extensions
• Maintains the texture and manageability of synthetic hair

Cons

• Color choices are limited compared to human hair dye
• Can’t lighten extensions, only darken them
• Heat styling should be avoided to preserve color
• Dyeing process is more tedious than human hair
• Color may fade quicker than human hair

Generally, dyeing synthetic extensions is great for achieving vibrant, fantasy hair colors on a budget. But human hair remains the best option if you want natural blonde/brown shades or need to lighten your extensions.

FAQs About Dyeing Synthetic Hair Extensions

How long does the synthetic hair dye last?

With proper care, the dye should last 1-2 months before fading. Avoid washing too frequently, use sulfate-free shampoo, and minimize heat styling.

Can I bleach or lighten my synthetic extensions?

Unfortunately, lightening synthetic hair is not recommended. The chemicals used to bleach hair will severely damage the synthetic fibers. You can only dye synthetics darker.

What’s the difference between dyeing synthetic vs human hair?

Human hair dye penetrates into the hair shaft for permanent color that grows out naturally. Synthetic hair dye only stains the outer layer of the fiber so it can wash out over time.

Can I use Kool-Aid to dye my extensions?

Although some people have had luck with Kool-Aid, it may not work as well as dye formulated for synthetic hair. Stick to trusted brands like Rit Dye for best results!

How do I dye lace front or closures?

Protect the lace by covering it tightly with a plastic bag or petroleum jelly. You only want to dye the hair strands, not the lace base they are attached to.
