Washing your wig should leave it fresh and clean—but sometimes, the opposite happens. If your wig smells musty, sour, or unpleasant after washing, you’re not alone. This is a common issue with both human hair and synthetic wigs, and thankfully, it’s easy to fix.
Let’s break down why your wig smells after washing and exactly how to get rid of the odour for good.
Why Does a Wig Smell After Washing?
A bad smell usually means moisture or residue is trapped in the wig. Here are the most common causes:
Common Causes of Wig Odour After Washing
1. The Wig Isn’t Fully Dry
This is the #1 reason wigs smell.
-
Water gets trapped in the cap, wefts, or lace
-
Damp wigs develop a mildew or musty smell
-
Thick or long wigs take longer to dry
Even slightly damp wigs can smell bad within hours.
2. Product Build up
Conditioners, oils, sprays, and glue residue can cling to the wig.
-
Build up traps odour
-
Heavy products weigh hair down
-
Residue prevents proper rinsing
This is especially common near the roots and cap area.
3. Using the Wrong Shampoo
Not all shampoos work for wigs.
-
Regular shampoos may leave residue
-
Scent-heavy formulas can mix with odours
-
Some products don’t rinse clean
Wigs need gentle, residue-free cleansers.
4. Sweat and Scalp Oils
Wigs absorb sweat and natural oils over time.
-
Odours linger in the cap
-
Heat makes smells stronger
-
Washing hair strands alone isn’t enough
The inside of the wig needs attention too.
5. Poor Air Circulation During Drying
Drying wigs in closed or humid spaces causes odour.
-
Laying wigs flat slows drying
-
No airflow = lingering smell
How to Fix a Smelly Wig (Step-by-Step)
Step 1: Rewash the Wig Properly
-
Use lukewarm water
-
Apply wig shampoo gently
-
Focus on the cap and roots
-
Rinse thoroughly until water runs clear
Never scrub or twist the wig.
Step 2: Deep Rinse to Remove Residue
-
Rinse longer than you think is necessary
-
Lightly squeeze (don’t wring) excess water
-
Make sure no product is left behind
Residue = trapped odour.
Step 3: Neutralize Odours Naturally
Choose one method:
✔ Apple Cider Vinegar Rinse
-
Mix 1 tablespoon ACV with cool water
-
Rinse lightly and rinse again with water
✔ Baking Soda Soak (Synthetic Wigs)
-
Add 1 teaspoon baking soda to water
-
Soak briefly, then rinse well
Step 4: Dry the Wig Completely
-
Gently blot with a towel
-
Place on a wig stand or mannequin head
-
Air-dry in a well-ventilated area
-
Avoid damp or enclosed rooms
This step is critical.
Step 5: Freshen After Drying
-
Lightly mist with wig-safe refresher spray
-
Avoid strong perfumes or alcohol sprays
-
Let it air out before wearing
How to Prevent Wig Odour in the Future
✔ Always dry wigs fully before storage
✔ Use lightweight, wig-safe products
✔ Wash wigs regularly but not too often
✔ Store wigs in breathable containers
✔ Avoid sleeping or working out in wigs
Human Hair vs Synthetic Wigs: Odour Differences
-
Absorb oils and sweat more
-
Need deeper cleaning
-
Require longer drying time
-
Trap odours in fibres
-
Need gentler products
-
Dry faster but still need airflow
Final Thoughts
If your wig smells after washing, it’s almost always due to trapped moisture or product build up—not poor quality. With proper washing, thorough rinsing, and complete drying, your wig will smell clean, fresh, and wearable again.
A fresh wig doesn’t just look better—it feels better too.
