Piano Black Platinum: Editorial Contrast on Bone Straight
Black and platinum are the two extremes of the tonal spectrum — maximum absorption versus maximum reflection. On a bone straight flat cuticle surface, alternating wefts in these two tones create a sharp, high-definition stripe effect that reads as editorial and intentional. The flat cuticle ensures both tones reflect light cleanly, with no frizz or texture to soften the contrast.
Style & Installation Options
- Sew-In Installs: Alternating black and platinum wefts produce a graphic two-tone movement across the full install — bold from every angle.
- Wig Builds: Use as bundles for lace front or closure wigs — the black and platinum contrast reads sharp and dimensional from root to tip.
- Lengths: 8″ to 30″ — tonal contrast remains consistent across all lengths, from a cropped bob to a floor-grazing install.

Maintenance & Care
- Washing: Platinum wefts are lightened and porous — use sulfate-free shampoo and cool water to prevent the blonde from yellowing or drying between installs.
- Heat Styling: Always apply heat protectant spray before flat-ironing, especially on the platinum wefts. Max heat: 350°F (175°C) — lower than standard to protect the lightened strands.
- Storage: Hang straight on a satin hanger — folding disrupts the bone straight alignment and stresses the lightened wefts.
Factory Insight — Mrs. Cherry, Sales Manager, K-Hair Factory:
“Platinum on bone straight is technically demanding — you’re lifting the hair to its lightest possible state while keeping the cuticle flat and aligned. If the lift is uneven across wefts, the platinum reads as yellow in some sections and white in others. We process every platinum weft to the same ash tone before assembly so the contrast with the black wefts is clean and consistent throughout the bundle.”
