You finally opened your brand-new Genius Weft Hair Extensions—ready for fuller, longer hair.
But instead of that fresh salon vibe, you notice a slightly chemical or musty smell.
If that caught you off guard, you’re not alone.
Short answer:
✅ Yes, a mild smell from new Genius Weft hair extensions is completely normal—and temporary.
This guide explains exactly why it happens, what it means (and doesn’t mean), and the safest ways to remove the smell before install.
Is It Normal for New Genius Weft Hair Extensions Smell?
Yes. A light, temporary odor is normal for new Genius Weft hair extensions.
Because Genius Wefts are made with 100% human hair, the hair extensions smell does not come from synthetic fibers.
Instead, it’s usually caused by professional cleaning, sanitization, and airtight packaging used to keep the hair hygienic during storage and shipping.
In most cases, the scent disappears after airing out or the first gentle wash.
Why Do New Genius Hair Extensions Smell?
Here are the most common and harmless reasons, especially for high-quality wefts like Genius Weft:
1. Professional Cleaning & Sterilization
This is the most common cause.
Before packaging, human hair extensions go through sanitization and disinfecting steps to remove bacteria and impurities.
Mild disinfecting solutions can leave behind a faint scent, which is actually a sign the hair was properly processed.
âś… Safe
âś… Temporary
âś… Fades quickly
2. Airtight Packaging During Shipping
Genius Wefts are sealed in plastic to stay clean and moisture-free.
Because human hair is porous, any residual scent from processing can become trapped and concentrated—especially during long-distance or overseas shipping.
Once exposed to fresh air, the hair extensions smell usually fades on its own.
3. Light Color or Styling Treatments
Some extensions receive gentle toning, dyeing, or conditioning treatments to enhance color consistency and shine.
These products can carry a mild scent that disappears after washing.
What the Smell Does NOT Mean
Let’s clear up the biggest misconceptions 👇
❌ It does not mean the hair is fake
❌ It does not mean the hair is dirty
❌ It does not mean the hair is damaged
If your Genius Wefts feel soft, smooth, have aligned cuticles, and minimal shedding, the quality is just fine.
How to Remove the Smell From Genius Weft Hair Extensions
âś… Step 1: Air Them Out
Hang the wefts in a well-ventilated room for 24–48 hours, away from direct sunlight.
For light odors, this step alone often works.
âś… Step 2: Gentle First Wash
If the smell remains, do a simple wash:
- Cool water
- Sulfate-free shampoo
- Rinse thoroughly
- Air dry completely
This removes nearly all residual odors without drying the hair.
âś… Step 3: Light Fragrance Boost (Optional)
Once dry, you may lightly use:
- A scented dry shampoo
- A leave-in conditioner spray made for extensions
Avoid anything heavy or alcohol-based.
What NOT to Do
đźš« Do not spray perfume directly on the hair
đźš« Do not soak extensions in vinegar or household cleaners
đźš« Do not apply heat while the smell is strong (heat can lock odors in)
The Bottom Line
A mild hair extensions smell from new Genius Weft is normal, temporary, and harmless.
It comes from cleaning, sterilization, and airtight packaging—not poor quality.
With a little fresh air or a gentle wash, your extensions will smell clean, feel soft, and be ready for install.

Frequently Asked Questions (FAQ)
Q: Is it normal for new hair extensions to smell?
A: Yes. New hair extensions often carry a mild scent from the sterilization and packaging process. This ensures the hair is clean and safe to wear and usually disappears after washing.
Q: How do you get the smell out of new hair extensions?
A: The safest method is washing with a sulfate-free shampoo in cool water, followed by air drying. For light odors, airing them out for 24–48 hours may be enough.
Q: Why do my Genius Weft extensions smell chemical-like?
A: That scent usually comes from gases or sanitizing solutions used during professional processing. Because the hair is sealed in airtight packaging, the smell can feel stronger at first—but it fades quickly.
