How Many Bundles Do You Really Need? The Belle Société Guide to Choosing the Perfect Amount & Length
Every woman asks this before installing extensions:
“How many bundles do I need?”
The truth is…
most people guess — or rely on whatever a stylist says.
But bundle quantity is NOT one-size-fits-all.
It depends on:
✔ your natural hair density
✔ your leave-out or closure
✔ your braid pattern
✔ your desired fullness
✔ your texture choice
✔ your length (VERY important)
✔ your head size + face shape
And because Belle Société bundles are cuticle-intact, organically washed, and full from root to tip, you get more styling freedom with fewer bundles.
This guide breaks it ALL down — professionally, simply, and Belle-approved.
How Many Bundles Do I Need? (Simple Breakdown)
Shorter Lengths (12”–16”)
✔ 2 bundles → natural density
✔ 3 bundles → full + glamorous
✔ 4 bundles → celebrity-level fullness
Because shorter hair has more weight per bundle, you get MORE fullness.
Medium Lengths (18”–22”)
✔ 3 bundles → natural fullness
✔ 3.5 bundles → glam, thick install
✔ 4 bundles → red carpet full
This is the most common length range and looks best with 3 bundles minimum.
Long Lengths (24”–30”)
✔ 4 bundles → standard full look
✔ 4.5 bundles → glam fullness
✔ 5 bundles → ultra-thick, influencer glam
Long bundles have less volume at the ends, so you need more for balance.

Choosing Bundles Based on Your Install Type
Leave-Out Sew-In
✔ 2–3 bundles for natural density
✔ 3–4 bundles for glam
Why?
Your real hair covers tracks, so you don’t need extreme fullness.
Closure Sew-In
✔ 3 bundles minimum
✔ 4 for glam fullness
Closure installs look best with balanced density.
Frontal Sew-In
✔ 3.5–4 bundles
✔ 4–5 for extra glam
Frontals need extra volume around the perimeter and back.
Traditional Sew-In With Minimal Leave-Out
✔ 3–4 bundles
✔ 4–5 for longer lengths
This is the most popular option for Belle shoppers.
How Texture Affects Bundle Quantity
Silky Straight
More bundles needed
Because straight textures show density more clearly.
→ Use Belle’s straight for sleek, full looks.
Body Wave
Medium bundle usage
Holds volume well with fewer bundles.
→ Perfect middle option.
Deep Wave / Curly
Fewer bundles needed
Because curls create natural fullness.
→ 2–3 bundles often enough.
Choosing the Right LENGTH for Your Face Shape
Oval Face
Any length — you’re blessed.
Round Face
Choose 18”–26” to elongate your look.
Square Face
Body wave in 20”–24” softens angles.
Heart-Shaped Face
24”–30” adds balance + softness.
Long Face
Choose 16”–22” with body + volume.
