How much hair do I need?
Adding fullness (no length): 1–3 packs (about 20–60 grams).
Adding length: 4–8 packs, depending on the client’s starting density — length needs roughly double the density of the natural hair for a seamless blend.
Full transformation (bob to long): 8–12 packs.
We always suggest ordering on the side of caution so you’re not left in a pinch — when in doubt, your LINEONE artist can confirm at consultation.
