How to Get Volume Back in a Synthetic Wig That Has Gone Flat

It happens to almost every synthetic wig after a few months of regular wear. The bounce is gone, the layers are sitting flat, and the whole style looks a bit tired. Before you write it off, there is a good chance the wig just needs the right kind of refresh. Most synthetic fibres respond well to a few simple techniques — and knowing which ones to use (and which to avoid) makes all the difference.

Why Synthetic Wigs Lose Volume

Synthetic fibre is made from plastic-based strands that hold their shape through heat-setting during manufacturing. Over time, a combination of factors flattens them out:

• Friction from wearing: Daily contact with your collar, headrests and hands compresses the outer fibres and smooths the cuticle-like texture that creates volume.
• Incorrect washing: Rubbing or wringing the wig during washing tangles and flattens the strands rather than separating them.
• Poor storage: Folding a wig into a bag or cramming it into a drawer crushes the style. Compressed fibres stay compressed.
• Moisture build-up: Putting the wig away damp, or wearing it in humidity without proper drying time, causes fibres to clump together as they dry in a flat position.

None of these are permanent — at least not initially. The fibre memory in a synthetic wig can be reset, within limits.

What Definitely Does Not Work

Before getting into what does revive volume, it is worth being clear about what will make things worse:

• A hairdryer on a standard synthetic wig. Standard synthetic fibres melt at temperatures above about 130°C. A hairdryer on even a medium heat setting can cause frizz, fusing, or permanent damage to the fibre. Unless your wig is specifically labelled as heat-friendly (usually noted as "heat-resistant" or "heat-friendly" up to 120–130°C), keep all heat tools away from it.
• Backcombing with a fine-tooth comb. This tears through synthetic fibres and creates frizz that cannot be reversed.
• Dry shampoo or volumising powder. These products coat the fibre and build up into a residue that makes the wig look dull and feel sticky over time.
• Vigorous brushing from root to tip. This creates static, pulls out strands, and flattens the style further. Always start from the ends and work upward.

Methods That Actually Work

1. The Cool Water Shake-Out

This is the first thing to try on any flat synthetic wig, and it works more often than people expect. Fill a basin or sink with cool water, submerge the wig completely, then gently swish it side to side for 30 seconds. Lift it out, hold it by the cap, and give it a few firm shakes to separate the fibres. Then hang it upside down on a wig stand or hanger and let it air-dry completely — do not touch it while wet.

As the fibres dry hanging freely, they separate from each other and can recover some of their original movement. Once fully dry, use your fingers to tease the hair gently from underneath at the roots.

2. Wide-Tooth Comb From the Ends Up

Use a wide-tooth comb or a wig brush (paddle brushes with ball-tipped pins are ideal). Start at the tips, work out any tangles, then gradually move upward toward the roots. Never drag from root to tip — this causes bunching and static.

Once the wig is detangled, use your fingers to lift sections at the root and give them a gentle shake. Finger-styling is kinder to synthetic fibre than any tool.

3. A Wig Pick for Root Lift

A wig pick — similar to an afro pick, with wider teeth and no sharp points — is one of the most underrated tools for synthetic wigs. Gently insert the pick at the root area, under sections of hair, and lift upward. Do not pull or drag. This creates air pockets at the base and lifts the style from the inside rather than pushing the outer fibres around.

You can find wig picks at most beauty supply stores for a few dollars. They are worth keeping in your kit.

4. Fabric Softener Rinse for Smoothing and Softening

If the fibre has become rough or stiff (rather than just flat), a fabric softener rinse can help restore the original texture. Mix about one teaspoon of fabric softener into a basin of cool water, submerge the wig for ten minutes, then rinse thoroughly with clean cool water and air-dry as above. Do not leave it to soak for longer — prolonged exposure can loosen the fibre construction on some wigs.

This works well for wigs that have become tangly or crispy, and the softened fibre tends to hold volume better after the treatment.

5. Steam (Heat-Friendly Wigs Only)

If your wig is heat-friendly (and the label says so), a light steam treatment can reset the fibre. Hold the wig on a stand, use a handheld garment steamer, and pass it slowly through each section at a distance of about 10 cm. Do not hold it in one place. Let the steam lift each section, then use your fingers or a wide-tooth comb to reshape it while it is warm and pliable. Let it cool completely before touching it further.

Steam is effective because it temporarily breaks the heat-set memory of the fibre, allowing you to reshape it. This is the closest a synthetic wig can get to a "blow-out" reset — and it genuinely works when the wig is the right type.

When the Wig Is Past Saving

There are signs that a synthetic wig has reached the end of its lifespan:

• The fibre has a permanent frizz or crinkled texture that does not respond to water, combing or steam
• There are visible patches of thinning or fibres coming away at the wefts
• The cap has stretched beyond its original shape and no longer sits properly
• The fibre has a dull, matted appearance even after washing

A quality synthetic wig worn regularly typically lasts 4–6 months with proper care. If yours has gone past that point, it may simply be time for a replacement — and that is not a failure, it is the nature of the fibre.

Preventing Flatness in the First Place

Volume is much easier to maintain than it is to restore. A few habits make a big difference:

• Store on a wig stand. This keeps the cap shape and allows the fibres to hang freely. If you do not have a stand, a foam head form works just as well.
• Wash no more than every 8–10 wears (unless you are sweating heavily). Over-washing wears out the fibre faster.
• Air-dry every time, upside down if possible. Drying right-side up flattens the root area from the weight of the wet fibre.
• Shake the wig out before putting it on, not just after taking it off. This separates fibres that have compressed during storage.

If you are looking for a wig that holds its shape well between wears, lace front styles generally have more layering and movement built into the construction than full-cap styles, which makes them a bit more forgiving on flat days. And our full synthetic collection has a range of options across different price points if it is time for a fresh start.

FAQ — Restoring Volume to a Synthetic Wig

Can I use a hairdryer on a flat synthetic wig?

Only if the wig is specifically labelled as heat-friendly (heat-resistant to 120–130°C). On a standard synthetic wig, a hairdryer — even on low — can melt or permanently damage the fibre. Stick to cool water and air-drying.

Why does my synthetic wig look flat after washing?

If the wig was rubbed or wrung out during washing, the fibres have been compressed. Let it drip-dry hanging freely (upside-down if possible), and do not touch it until it is completely dry. Once dry, use a wide-tooth comb from ends to roots and a wig pick at the roots to restore lift.

Does fabric softener actually work on synthetic wigs?

Yes — a diluted fabric softener rinse (about one teaspoon per basin of cool water) can soften stiff or roughened synthetic fibres and help them separate more easily. Rinse thoroughly afterwards. Do not use it as a substitute for wig-specific conditioner on wigs you wash frequently, as it can build up over time.

How do I add volume at the roots specifically?

A wig pick inserted gently under sections of hair at the root and lifted upward is the most effective tool. You can also try teasing (very gently, with a wide-tooth comb) at the very root area, but do this sparingly as it can cause tangling in some fibres. Avoid any product that claims to "volumise" — most of these coat the fibre and cause build-up.

How long should a synthetic wig last before it goes flat permanently?

With regular wear (4–5 times per week) and reasonable care, most synthetic wigs last 4–6 months before the fibre begins to break down permanently. Occasional wear can extend that to 12 months or more. If yours is going flat much sooner, check your washing technique and storage — those are the two most common causes of premature wear.
