Why Choose 40-Inch Clip-In Hair Extensions?

These extensions don’t just add length — they create luxurious volume that blends seamlessly with your natural hair when installed correctly.
What Are Clip-In Hair Extensions?
Clip-in extensions are wefts of hair attached with small, pressure-sensitive clips that you can secure into your natural hair. They’re temporary, non-damaging, and can be installed at home in minutes.

Why Raw Vietnamese Hair Is Perfect for 40-Inch Clip-Ins
At 40 inches, weight and quality are critical. Lower-grade hair may thin out toward the ends or tangle easily. Raw Vietnamese hair is ideal because:
-
It’s naturally thick and strong, even in longer lengths
-
The cuticle is intact and aligned, preventing tangles
-
It blends beautifully with straight, wavy, or coarse textures
-
It holds curls or styles longer, even in humid weather
Vietnamese hair is also ethically sourced from healthy donors, ensuring a natural, soft texture that lasts.
How Many Grams of Hair Do You Need for 40 Inches?
Due to the extra length, you’ll need more grams of hair to maintain a full and natural look.
| Length | Recommended Weight for Full Head |
|---|---|
| 24 inches | 200g |
| 30 inches | 250g |
| 40 inches | 300–350g |
Most professional clip-in sets include 7 to 10 wefts to cover your head from ear to ear. Look for sets that specify thickness from top to ends, as many cheap brands provide thin bundles.
