A formula from another salon has a /8, and you work with Igora
Case of the week · October 5
- Formula brought in
- Koleston Perfect, /8 reflect
- Your brand
- Igora Royal
Your client brings a written formula: a Koleston Perfect with a /8 reflect. You work with Igora Royal, and the same number exists there: -8.
What do the two manufacturers say about the 8?
What the manufacturer says
The Koleston Perfect booklet calls /8 “Pearl (blue)”, and the Igora chart calls -8 “Red”. Same number, different reflect: reading Koleston’s /8 with Igora’s key turns a cool pearl into a warm red. Before moving a formula across brands, check each brand’s key.
