The care and maintenance of synthetic hair extensions can significantly impact their longevity, appearance, and overall performance. Washing these extensions is a crucial part of this care routine. Properly cleaned extensions last longer and maintain their natural look and feel, closely mimicking your natural hair.

However, washing synthetic hair extensions is not as straightforward as washing natural hair. It demands careful attention, the right products, and a delicate touch to ensure they remain in prime condition. The subsequent parts of this guide will detail a step-by-step process for washing synthetic hair extensions correctly. From preparation to drying, it will cover everything you need to know.

How To Wash Synthetic Hair Extensions

Preparation and Materials Needed

Gathering all the necessary materials before you start washing your synthetic hair extensions is essential. You will need:

Wide-toothed comb or brush

It would be best if you always used a wide-toothed comb or brush when washing synthetic hair extensions. This type of comb reduces the risk of tangling and ensures gentle detangling.

Basin or sink

You will need a basin or sink filled with lukewarm water to wash your extensions. Do not use hot water, as it can damage the fibers of your synthetic hair extensions.

Mild shampoo or wig shampoo

A mild or wig-specific shampoo is crucial for keeping your synthetic hair extensions in top condition. Avoid using regular shampoos as they can contain harsh chemicals that can strip the hair of its natural oils and damage it. You should also use the right kind of shampoo when washing dyed synthetic hair.

Fabric softener (optional)

Adding a small amount of fabric softener to the water while washing can help to keep the extensions soft and smooth. However, this step is entirely optional.


You will need two towels – one to dry the extensions and another to wrap around your head while washing. You can also use a microfiber towel, which is gentler on the hair and reduces frizz.

Washing Process

Step 1: Detangle

Before you begin the washing process, it is crucial to detangle your synthetic hair extensions to prevent any possible damage during washing. Because of the workings of hair extensions, always start detangling from the bottom and work your way up to the roots. Hold the hair at the root area to prevent pulling and stress on the extension bonds.

Use a wide-toothed comb or a brush specifically designed for extensions. Gradually comb through the extensions, ensuring you are not pulling or tugging at the hair. Gentle, patient detangling reduces the risk of hair breakage and extension damage.

If you come across a particularly challenging knot, don’t force it. Instead, apply a little detangling spray or leave-in conditioner to the troubled area and gently work through the knot. Remember, the goal is to keep your extensions in the best possible condition, and taking the time to detangle carefully and methodically is a primary step in doing so.

Step 2: Wet the Extensions

Next, wet your extensions. You can place them in a large bowl or clean sink filled with lukewarm water. Ensure that all strands are fully submerged. You can also use a showerhead attachment to wet your extensions while they are clipped in. Avoid using hot water, as it can damage and tangle the hair.

Step 3: Apply Shampoo

Take a small amount of shampoo designed for synthetic hair and gently massage it into the extensions. Be sure to distribute the shampoo evenly across the extensions, but avoid rubbing as this can cause tangles. You can also mix a small amount of fabric softener with the shampoo to add extra softness and smoothness to the hair.

You should also avoid using too much shampoo, as this can be difficult to rinse out and leave a residue on the extensions. Stick to a small amount and add more if necessary. Focus on the extensions’ roots and mid-lengths, as these areas get dirtier than the ends. You can also use a gentle, downward stroking motion with your fingers to work the shampoo in.

If you are washing clip-in extensions, avoid getting the clips wet. Instead, focus on the wefts and gently massage shampoo into them. This step will help to remove any dirt, oils, or product buildup from the wefts and keep them clean.

Step 4: Rinse

Rinsing is an integral part of the washing process as it helps to remove shampoo, dirt, and any other residues from synthetic hair extensions. Remove the extensions from the basin or sink and hold them under a stream of lukewarm water. Adjust the water pressure to a gentle flow to avoid tangling the hair.

Start from the top (root area) and allow the water to flow down to the ends of the extensions. This method helps to keep the direction of the water consistent with the direction of the hair, thus reducing potential tangles. While rinsing, use your fingers to gently work through the hair, ensuring the water and movements are removing the shampoo. This also helps to dislodge any leftover dirt or grime.

Ensure all the shampoo is thoroughly rinsed out, as any remaining residue can build up over time and make the extensions look dull and lifeless. Additionally, leftover shampoo can dry out synthetic hair, leading to frizz and tangling. Therefore, take your time during this step, ensuring the water runs clear and free of bubbles before concluding that the rinsing process is complete.

After ensuring that the extensions are thoroughly rinsed, carefully squeeze out any remaining water. It is important to avoid wringing or twisting the hair, as this can lead to tangles and potential damage to the extensions.

Step 5: Apply Conditioner

While synthetic hair does not benefit from the typical nourishing properties of conditioner, a specially formulated conditioner can help keep the extensions soft, manageable, and tangle-free. You will need a synthetic hair conditioner or fabric softener for this step. Apply a generous amount of conditioner to the extensions. Start from the mid-lengths and work your way down to the ends, avoiding the roots and the bonds. Leave the conditioner in for a few minutes to allow it to penetrate the fibers of the synthetic hair.

It’s worth noting that synthetic hair conditioner is very different from the conditioner used on natural hair, so it’s essential to ensure you’re using the right product. Do not rinse the conditioner immediately; let it sit for 3-5 minutes. This waiting period allows the conditioner to envelop the hair fibers and soften them. When the time is up, rinse the conditioner out thoroughly, ensuring no residues are left behind. As when rinsing the shampoo, use lukewarm water and start from the top, letting the water flow down.

Step 6: Dry the Extensions

Drying your synthetic hair extensions correctly is as important as washing. Incorrect drying can lead to tangles, frizz, and damage to the hair fibers. Start by gently squeezing out excess water from the extensions. Again, avoid wringing or twisting the hair too much, as this can cause unnecessary tension and potential damage.

Lay a clean, dry towel flat on a table or countertop and place the wet extensions on it. Roll the towel with the extensions inside, pressing gently to absorb the water. Do not rub the extensions, as this can cause frizz and tangles. Allow the extensions to stay wrapped in the towel for a few minutes.

After you’ve removed the excess water, you can allow the extensions to air dry. Place them on a flat surface, like a dry towel or a drying rack, and allow them to dry naturally. Do not comb or brush the extensions while wet, as this can lead to breakage. If you need to detangle them, wait until they are at least 90% dry before using a wide-tooth comb.

If you are in a hurry and need the synthetic hair extensions to dry faster, you may use a blow dryer. However, use the lowest heat setting or a cool shot feature, as high heat can damage synthetic hair. Keep the dryer at least 12 inches away from the extensions, moving it continuously to prevent overheating any section of the hair.

Finally, once the extensions are completely dry, brush them gently to ensure they are free of tangles and ready for use. Now, your synthetic hair extensions should be clean, soft, and shiny, ready to enhance your hairstyle.

Ways To Wash Synthetic Hair Extensions

Alternative Methods for Washing Synthetic Hair Extensions

While the traditional washing method is highly effective, there are alternative ways to clean your synthetic hair extensions, such as using dry shampoo or DIY spray solutions. These can be particularly useful if you’re in a rush or the extensions are not excessively dirty.

Dry Shampoo

Dry shampoo can be a lifesaver when refreshing your synthetic hair extensions between washes. It absorbs excess oil, removes mild dirt, and leaves the hair smelling fresh. To use dry shampoo, separate your hair extensions into sections and lightly spray the dry shampoo onto the roots and mid-lengths. Avoid spraying too much to prevent a powdery residue. After application, use a comb or your fingers to distribute the product evenly throughout the extensions. Leave the dry shampoo in for a few minutes to absorb the oil and dirt, and then brush through the extensions to remove any excess product.

DIY Spray Solutions

You can create a DIY spray solution that can help keep your synthetic hair extensions clean and fresh-smelling between washes. One popular option is a mix of water and fabric softener. Just fill a spray bottle with water, add a few drops of fabric softener, shake well, and spray it onto your extensions. The fabric softener not only helps to detangle and soften the hair but also leaves a pleasant scent. Remember to comb through the extensions after application to ensure even solution distribution.

Another DIY solution involves mixing water with a small amount of mild shampoo. This mixture can be sprayed onto the extensions, gently worked in, and then rinsed. As with the other methods, remember to squeeze out any excess solution and allow the extensions to dry naturally.

These alternative washing methods can be used judiciously, but it’s important to remember that they are not replacements for a thorough wash. Regularly washing your synthetic hair extensions using the traditional method is still necessary to maintain their quality and longevity.

Regular Maintenance and Products for Keeping Extensions Fresh Between Washes

Maintaining your synthetic hair extensions is as important as washing them. Regular and proper maintenance enhances the look and feel of your extensions and extends their lifespan.

Regular Brushing

Regularly brushing your synthetic hair extensions prevents tangles and matting. Always use a wide-toothed comb or a brush specifically designed for synthetic hair. Gentle detangling from the ends to the roots will ensure the extension fibers aren’t damaged and maintain their smooth texture.

Heat Protection

Synthetic hair is sensitive to high temperatures. Therefore, avoiding exposure to direct heat from hair dryers, straighteners, or curling irons is advised. If you need to use these tools, always use a heat protection spray and the lowest heat setting.

Specialized Products for Synthetic Hair

Using products specifically designed for synthetic hair is crucial to extension maintenance. These include synthetic hair conditioners, detangling sprays, and heat protectant sprays. These products help maintain the extension’s luster, prevent tangles, and protect them from heat damage.


How you store your extensions when not in use can also affect their quality. Always ensure the extensions are clean, completely dry, and detangled before storage. It is best to store them in a dry and cool place, away from direct sunlight and heat. You can also consider purchasing a storage case or hanger designed for extensions to keep them in the best possible condition.

Remember, while synthetic hair extensions add volume and style to your hair, they require a committed care routine. Regular maintenance and the proper products can keep your synthetic hair extensions looking fresh and natural for a longer period.

Bottom Line

Maintaining and caring for synthetic hair extensions is essential to keep them looking their best. This includes washing them regularly using the proper methods, brushing them gently, using heat protection products, and storing them correctly. With these tips, you can enjoy beautiful, long-lasting extensions that enhance your hairstyle effortlessly.
