When figuring out how many bundles of hair you'll need for a full head, there are various things to consider, such as hair texture, the amount of fullness you're aiming for, and the extensions' length. Below is a quick guide to estimate:
1. Hair Texture and Density
Fine or thin hair generally needs 2–3 bundles for a natural appearance, whereas medium to thick hair can use 3–4 bundles for proper coverage. Thicker or curlier textures (such as 3B–4C) tend to require 3–5 bundles due to the volume and shrinkage of their texture.
2. Fullness Desired
For a light or medium fullness, 2–3 bundles are typically enough. For a full, voluminous look, particularly for longer lengths (18–24 inches), 4–5 bundles are recommended.
3. Extension Length
Shorter lengths (8–14 inches) might only require 2–3 bundles, but longer lengths (16–24 inches) tend to need 3–5 bundles to prevent a thin look.
4. Installation Technique
Sew-ins or weaves might require fewer bundles than tape-ins or clip-ins because the latter can spread hair more evenly.
5. Closure or Frontal
When employing a closure (covers a small area) or frontal (covers the full front hairline), you may require 1–2 fewer bundles because these pieces provide volume.
General Rule of Thumb:
- 2–3 bundles: Light coverage, shorter lengths, or fine hair.
- 3–4 bundles: Average coverage, average hair thickness, or lengths to 18 inches.
- 4–5 bundles: Fullness to the max, longer lengths, or curly/thick hair.
Always ask your stylist for a personal recommendation, as everyone's needs are different.
