DEMI Assault Arias Deep Natural: levels and tones
The DEMI Assault Arias Deep Natural line is a Japanese professional hair dye range covering a spread of depth levels and undertones. This guide explains how the level numbers and the tone codes work, what the self-dye option adds, and how to read a shade name so you can find the right match.
What is in this collection
This collection gathers 17 or more shades of the DEMI Hair Dye Assault Arias Deep Natural Line, plus a self-dye Cover Hair option. The shades span Deep Natural levels D-5 to D-9, each offered in undertone variants marked WB, CB and BB. Every listing is part of the same Deep Natural family, so the choice is about level and tone rather than a different product.
About DEMI
DEMI is a Japanese beauty brand, and Assault Arias is its hair-colour series. These are salon-style cream colours of the kind colourists work with, which is why the range is organised by precise levels and tone codes rather than simple named shades. The system is built for people who want to match depth and warmth accurately.
Reading the level numbers (D-5 to D-9)
The D number is the depth level. In this collection it runs from D-5 through D-9. A lower number is a darker, deeper result and a higher number is lighter. So D-5 sits at the darker end of the Deep Natural range and D-9 at the lighter end. Picking your level is the first decision, since it sets how dark or light the finished colour reads.
Reading the tone codes (WB, CB, BB)
The letters after the level are the undertone. This line uses WB, CB and BB codes, which describe the warmth or coolness of the colour at a given level. Two shades at the same D level can finish differently depending on their tone code. Choose the tone that suits the look you want once you have settled on the depth level.
The self-dye Cover Hair option
Alongside the salon-style line, this collection includes a self-dye Cover Hair option for men and women, listed in the Deep Natural D-8 BB shade. It is aimed at people who want to apply colour at home rather than in a salon chair. If you are not working with a colourist, this is the more approachable way into the Deep Natural range.
How to pick a shade
Work in two steps. First choose the depth level, from the darker D-5 up to the lighter D-9. Then choose the tone code, WB, CB or BB, to set the warmth. Reading a name like Deep Natural D-7 / CB simply tells you the level is 7 and the tone is CB. If you are unsure and colouring at home, the self-dye Cover Hair option is the easiest place to begin.
Who this suits
This range suits colourists and confident home users who want a Japanese professional dye with precise control over depth and tone. The wide spread of D-5 to D-9 levels and multiple tone codes means there is room to fine-tune, while the self-dye option opens the line up to people colouring without a salon.

FAQ
Frequently asked questions
What is the DEMI Assault Arias Deep Natural line?
It is a Japanese professional hair dye range from DEMI's Assault Arias series. This collection carries 17 or more shades across Deep Natural levels D-5 to D-9, in several undertones, plus a self-dye option.
What do the D-5 to D-9 level numbers mean?
The D number is the depth level. A lower number is darker and deeper, a higher number is lighter, so D-5 is the darker end of the Deep Natural range and D-9 the lighter end. Choosing your level sets how dark or light the result reads.
What do the WB, CB and BB tone codes mean?
The letters after the level are the undertone, describing the warmth or coolness at that depth. Two shades at the same D level can finish differently depending on whether they are WB, CB or BB, so pick the tone after you have chosen the level.
Is there a Deep Natural option I can apply at home?
Yes. Alongside the salon-style line, the collection includes a self-dye Cover Hair option for men and women in the Deep Natural D-8 BB shade. It is the more approachable choice if you are colouring without a colourist.
How do I read a shade name like Deep Natural D-7 / CB?
The number is the depth level and the letters are the tone. D-7 / CB means a level 7 depth in the CB undertone. Decide on the level first, then the tone code, to land on the shade you want.
