The number of hair extension packs you need depends on your stylist’s approved amount and the contents of the exact product. A pack is a sales unit, not a universal full-head quantity. Establish the intended installed weight or piece count first, then convert that plan into the packs you need to purchase.
Starting density, haircut, desired length, fullness and attachment method all affect the plan. A photograph or a row count alone cannot establish the amount suitable for your hair.
Keep the units separate
| Unit | What it means | What it does not establish |
|---|---|---|
| Pack | The product’s packaging or sales unit | A universal quantity for a complete installation |
| Weft or piece | One supplied component | The total weight or the number of rows |
| Grams | The weight supplied or planned for use | How the hair should be distributed |
| Row | Part of an installation design | A fixed number of packs or wefts |
For example, Luxe Hand-Tied Silky Straight and Ethos Genius Silky Straight have different constructions. Do not assume their packs contain the same weight, width or number of pieces. Confirm the current details for the chosen length and pack configuration.
Use the calculation after the consultation
For a weight-based weft plan, divide the approved total grams by the grams in the selected pack, then round up to whole packs. For a plan expressed in pieces, use the approved piece count and the number of pieces in that exact pack.
The calculation translates an established service plan into a purchase. It does not determine the appropriate installed weight, and rounding up does not mean every supplied piece should be fitted.
If the plan uses more than one product, length or shade, calculate each line separately. Do not add unlike pack types together and treat the combined count as a useful installation measurement.
Why similar looks may require different orders
Adding fullness near an existing length is a different task from making a substantial length change. The natural ends need to meet the extension hair in a way that supports the desired silhouette. Placement and shaping may be as important as the amount purchased.
A blunt cut and a layered cut can create different blending needs even when the inspiration picture is the same. Ask the stylist what each part of the proposed quantity is intended to accomplish.
Construction also matters. The stylist may fit intact Hand-Tied pieces differently from a custom-cut Genius weft. That design should be settled before converting the plan into packs.
Allocate dimensional color shade by shade
A color plan may need several shades while using only part of some packs. Record the purchase and installation quantities separately for each shade. Leftover hair is not a reason to increase the installed amount beyond the approved plan.
Use the Standard Color Ring or Ethos Color Ring as appropriate to confirm the color specification. Keep the full shade code, collection and length on every order line.
Approve the complete order
- Confirm collection, construction, texture, shade and length.
- Read the selected listing’s pack weight, pieces and width where stated.
- Record the intended installed amount separately from the amount purchased.
- Have the installer approve each product and shade quantity.
- Check the delivered labels and seller’s opening conditions before installation.
If a measurement or pack detail is missing, ask Bohyme or the authorized seller to clarify the exact item. The weft measurement guide explains how to read the specifications without mixing units.
Quantity questions
Does one full pack mean a full head?
No. “Full pack” identifies a packaging option within a product listing.
Is there a universal minimum number of packs?
No. The correct quantity depends on the individual service and exact product contents.
Why might I have unused hair?
Whole-pack purchases and shade blending can leave more hair purchased than the stylist needs to install.
