Use three layers in your notes. The first is appearance: the parting, density, colour impression, silhouette, and whether the piece photographs differently in open light. The second is construction: a seam, cap, lace, knot, clip, comb, strand, or edge that appears displaced or altered. The third is your own scalp or skin experience. Keep each layer separate because a visual mismatch does not explain a scalp symptom, and a scalp symptom does not prove that the piece needs repair.
For appearance, compare like with like. A phone camera may change white balance, while sea glare can make a fibre look lighter. For construction, describe only what you can see without pulling or opening parts. For your scalp, record when discomfort, redness, swelling, tenderness, or a new area of hair change began. If a change is sudden, painful, inflamed, or patchy, pause the styling decision and seek appropriate medical assessment rather than treating the piece as the cause.
A care instruction is part of the evidence file. The American Cancer Society advises using products made for wigs, avoiding hairdryers or curling irons unless the piece is heat-resistant, and storing a wig on a stand for short periods when it is not worn. It also advises gentle handling, no rubbing, and waiting until the piece is dry before brushing after washing. Apply only the instructions that fit your material and provider guidance; do not assume every hairpiece has the same construction. [1]
The same boundary applies to menopausal hair loss. The wording may help you describe a search topic, but it does not establish that your change has that cause. If there is pain, marked redness, swelling, sudden patchy loss, or another worrying change, seek qualified medical evaluation. A hairpiece consultation can address appearance and construction; it should not replace that evaluation.
