A catalog photo shows you a hair — not your hair. Any supplier can photograph one flawless bundle and sell a hundred lots against that image.
Ask instead for a video of the specific lot that will ship to you, shown from the tied end to the tips, not only a flattering close-up.
If a supplier hesitates on this request, that hesitation is the answer.
Professional wig work — especially celebrity-level and editorial pieces — usually needs longer core lengths to allow for layering, cutting loss and client customization.
Ask for the supplier's full length range up front, not just their shortest, cheapest tier.
A strong range to look for: 40–75 cm.
A color name on a swatch card is not proof of what will arrive. Undertone varies between monitors, lighting and printed cards.
Ask whether the supplier's colors are shown as real lots on video — natural black through natural blonde — so you can judge undertone and variation the way your clients will see it in daylight.
