PROFESSIONAL HAIR EXTENSION GUIDE
A supplier change does not need to start with an entire range. Start with one commercially important product and a clear record of which characteristics must remain consistent.
QUICK ANSWER
Document one current SKU, send a physical reference, agree a matching sample specification, test both products side by side, approve the reference and written version, then evaluate a controlled first order before expanding.
KEY FACTS
Record construction, hair definition, usable length, net hair weight, end fullness, colour, strand or piece count, packaging and the selling unit. Separate characteristics that must match from improvements you are willing to consider.
Where the old supplier has no written specification, measure the physical reference and record what is known and what still needs agreement. Keep the sample labelled so later comparisons use the same product.
A current finished extension helps communicate colour placement and construction. A colour ring or swatch can support the brief; a photograph alone cannot guarantee exact colour or structural matching.
Confirm sample feasibility, quantity, cost and timing for the intended material and colour. Do not transfer historical sample terms to a new quotation without confirmation.
Compare the hair and attachment before and after the same handling steps. Retain the approved sample and observations as the reference for the first production order and later replenishment.
| Field | Record and compare |
|---|---|
| Colour | Physical shade, root, transition and blend placement |
| Weight and length | Net hair grams, usable length and measurement method |
| Fullness | Length profile, measurement method and reference positions |
| Construction | Weft edge, tape tab or keratin bond dimensions and stability |
| Handling | Same washing, drying, brushing and styling procedure |
| Pack configuration | Pieces or strands, labels, selling unit and packaging |
Use a documented sample evaluation method · Agree the end-fullness measurement
Record accepted differences, tolerances and any outstanding changes. Keep the approved physical sample linked to its specification, colour reference and SKU.
If the sample is revised, label the new version and record what changed. A message saying “same as before” is not a substitute for an identified production reference.
Confirm the first order scope, pack units, packaging and shipment details. Compare received production with the approved reference before widening the transfer to other colours or constructions.
Document any issue against the same acceptance criteria, retain the affected sample and agree the next step with the supplier. Expand only after the product and repeat-order process have been reviewed.
Retain the physical sample, written specification, artwork revision and order record. A change to material, colour, attachment or pack configuration needs its own approval.
The same process can qualify a primary supplier, a backup manufacturer or a second source. Each route still needs its own approved product reference.

No. Qualify one product and review its first production order before extending the transfer.
No. It can communicate direction, but light, camera and screen differences prevent exact approval.
Do not assume identity before testing. Agree the measurable requirements, tolerances and accepted differences.
