Short answer: for most full-head styles in human hair, 2 to 4 bundles. But the honest answer depends on four things — and getting it wrong is why people either run out mid-install or end up with three unopened packs.
Here's how to work it out before you order.
What actually changes the number
1. Your length. Longer braids don't just need longer hair, they need more of it. Going from 18" to 24" typically pushes you up a bundle.
2. Your braid size. Small braids eat hair. Jumbo braids use far less. This is the single biggest variable — bigger difference than length.
3. How full you want it. A soft, airy boho look and a thick "braids where?" install can differ by two full bundles on the same head.
4. Your own hair. Thick natural hair needs less added hair to look full. Fine hair needs more to get the same density.
Human hair — bundle guide
Every Fula Beauty bundle is 100g, available in 18" and 24".
| Look | Bundles |
|---|---|
| Light boho — soft, airy, minimal added hair | 1 |
| Natural volume — the everyday full look | 2–3 |
| Extra full — maximum density | 4 |
Most people land on 2 to 4.
Going longer or smaller? Add one bundle if you're doing 24" and small braids — that combination is the most hair-hungry.
By style
| Style | Typical range | Note |
|---|---|---|
| Boho braids | 1–3 bundles | Only the curly ends are added, so you need less than you'd think |
| Knotless braids | 2–4 bundles | Full-length feed-in — the most common range |
| Goddess braids | 2–3 bundles | Similar to boho, with more added at the ends |
| Mermaid / micro braids | 3–4+ bundles | Small partings, high hair count |
Human or synthetic — which do you need?
| Human hair | Synthetic | |
|---|---|---|
| Reusable | Yes — wash, take down, re-install | No, single use |
| Heat | Can be curled, straightened, dyed | Limited |
| Feel | Lighter, no itch | Can be heavier |
| Cost per install | Higher up front, lower over time | Lower up front |
| Wet & wavy effect | Curl pattern returns with water | Depends on the fiber |
If you re-install the same style every couple of months, human hair usually costs less over a year — you're buying it once instead of every time.
Still not sure?
Order one bundle more than you think you need. Unopened bundles keep indefinitely, and running out mid-install means matching a dye lot later — which rarely goes well.
