Shopping the DEMI Assalt Arias hair dye range
The Assalt Arias name covers DEMI's professional permanent dyes, and this collection pulls together the codes we keep in stock. Below you will find how the range is organised, what a developer does to the result, and a practical way to settle on one code.
Where the Arias name comes from
You will see the same line written as both Aria and Arias across the labels, for example Assalt Aria C and Assalt Arias Deep Natural. They belong to one DEMI dye family. The Deep Natural Arias codes make up most of this collection, with the Aria C and the Aria S Camelbage shade filling out the warmer and beige ends.
Why these are permanent dyes
Assalt Arias is an oxidative colour, which means it develops chemically with a peroxide cream rather than sitting on the surface like a wash-out tint. That is what gives it long wear and dependable grey coverage. It also means the colour keeps developing for the processing time, so timing and developer choice change the outcome more than with a temporary product.
Depth numbers across the range
In this collection the depth numbers cluster around D-5, D-7 and D-8. Treat the number as a lightness scale where a lower figure is darker. D-5 reads as a deeper brown, D-7 as a true mid brown, and D-8 as a softer light brown. If you are unsure, the middle of the range usually translates most predictably onto darker natural hair.
Warm, cool and neutral bases
The base letters decide the undertone. WB runs warm, CB runs cool, and BB sits as a neutral brown base. The same depth in different bases, such as D-7 / CB next to D-7 / BB, gives you a way to dial warmth up or down without changing how light the result is. Match the base to what you want to correct in the existing colour.
The Camelbage and Aria C options
Outside the Deep Natural codes you will find the Aria S Camelbage 12/11CaB, a lighter beige-brown that is handy for toning down brassy warmth on lifted hair, and the Aria C Hair Dye 8 WB for a warmer lighter brown. These mix on the same system, so you can pair a base colour with a toning shade from within the one range.
Pairing the dye with a developer
Each of these dyes is mixed with an oxidising developer before application. A lower-strength developer keeps the colour close to the natural depth, which is what you want for clean grey coverage, while a higher strength lifts first and then deposits. Use the ratio specified for the line and process for the stated time, checking a strand to confirm the tone.
A simple way to choose
Start by fixing the depth you want, then pick the base for the undertone, then check whether a Camelbage or Aria C glaze would refine the finish. Buying by code in this order keeps the choice reliable, because the swatch alone cannot show how a shade will develop over your current base.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
Are Aria and Arias the same DEMI line?
Yes. The labels use both spellings, for example Assalt Aria C and Assalt Arias Deep Natural, but they are one DEMI dye family. The Deep Natural codes form the bulk of this collection.
Which depth numbers are stocked here?
The range centres on D-5, D-7 and D-8. Lower numbers are darker, so D-5 is a deeper brown, D-7 a mid brown, and D-8 a lighter brown.
What does the BB base mean?
BB is a neutral brown base that sits between the warm WB and cool CB options. It is useful when you want depth without pushing the result obviously warm or ashy.
Is this a permanent dye or a wash-out colour?
It is permanent. Assalt Arias is an oxidative dye that develops with a peroxide cream, so it does not wash out the way a temporary tint does and it gives lasting grey coverage.
When would I use the Camelbage shade?
The Aria S Camelbage 12/11CaB is a beige-brown tone, good for calming brassy warmth on lifted or lightened hair without dropping into a flat ashy result.
Do I have to mix it with a developer?
Yes. These dyes are mixed with an oxidising developer before use. The developer strength controls how much the colour lifts before depositing, so follow the line ratio and run a strand test.
