How to match DEMI Hair Line WB shades to a hair goal
This DEMI Hair Line WB collection includes 5+ live Assalt Arias Deep Natural Line shades: D-4 / WB, D-5 / WB, D-7 / WB, D-8 / WB, and D-9 / WB. Use it to choose the WB depth that matches a specific hair color goal.
Start with the hair goal
Before comparing the five live WB shades, decide the result you want: deeper natural, mid-depth refresh, or lighter WB-family finish. The product grid should support that plan, not replace it.
Once the goal is clear, the D number becomes easier to choose.
Use D-4 / WB and D-5 / WB for deeper plans
D-4 / WB and D-5 / WB are the deeper live options in this collection. They are the first products to compare when your formula calls for a lower depth.
Check the product page and formula notes before choosing between them, because one number can still change the finished look.
Use D-7 / WB as a middle comparison point
D-7 / WB sits between the deeper and lighter live options. It is a useful reference shade when deciding whether the result should move darker or lighter.
If you have used a DEMI WB shade before, compare your old result against D-7 / WB before moving to D-8 or D-5.
Use D-8 / WB and D-9 / WB for lighter WB goals
D-8 / WB and D-9 / WB are the lighter live choices in this five-shade set. Choose them only when your hair plan supports that depth.
Starting level, previous color, and developer choice all affect whether a lighter WB shade can reach the result you expect.
Keep formula discipline
Record the exact DEMI line, D number, WB suffix, developer, timing, and outcome. This is the best way to make a successful WB result repeatable.
For salon restock, keep those notes tied to the client or formula card. For home use, keep them with your order history.
Test before a major depth change
Moving from D-4 / WB to D-9 / WB is a major depth change inside the same tone family. Strand testing helps reveal whether the planned shade is realistic.
Patch testing remains important with any hair dye product.
