| Fiber | Human hair, blend or synthetic; whether the seller defines “virgin” and “Remy” | These terms are often used inconsistently. |
| Processing | Color, steam texture, coating and chemical processing disclosed for this SKU | Processing can change feel, color options and care needs. |
| Texture | Straight, body wave, deep wave or curly; whether photos show the same length and density | Texture names are more useful than a broad country label. |
| Density + length | Stated density, measured length, bundle count and whether length is stretched | Two wigs with the same label can look very different. |
| Cap + lace | Cap size, adjustable range, lace area, knot treatment and return restrictions | Fit and construction usually matter more than the hair-origin name. |
| Returns | Return window, restocking fee, condition rules and who pays return shipping | Protects you when color, texture or fit differs from the listing. |
