DEMI Deep Natural self-dye satchets: codes, finishes and how to choose
The DEMI satchets in this collection share the Deep Natural descriptor but split across a few shade codes and two finish letters. Here is how the line is organised and how to land on the right one.
What Deep Natural means on a DEMI satchet
Deep Natural is DEMI's name for its grey-coverage tones that aim to read as natural dark hair rather than a fashion shade. Across this collection the Deep Natural label shows up on the Cover Hair Satch satchets and on the Arias Deep Natural line, so it is the common thread linking these otherwise separate codes.
BB versus WB finishes
The letters after the code mark the finish family. The BB satchets here, such as D-7 and D-8, sit in one tone family, while the WB option on D-4 sits in another. If you have used a DEMI shade before, matching the same finish letter is the easiest way to keep your result consistent from one satchet to the next.
Reading the D-numbers
The number tracks depth. Lower numbers like D-4 land lighter, while higher numbers like D-7 and D-8 go deeper. Pair the number with the finish letter to place a shade: D-8 / BB is among the deepest options in this grouping, and D-4 / WB sits at the lighter end.
Cover Hair Satch and the Arias line
Most of these are Cover Hair Satch satchets, DEMI's straightforward home-dye format. The collection also includes a satchet from the Arias Deep Natural line in D-8 / WB. Both share the Deep Natural intent, so if you want a deep WB result the Arias entry is worth a look beside the Cover Hair Satch codes.
Who these satchets suit
The packs are written for both men and women, and the Deep Natural depths are built around covering grey without an obvious dye line. If your goal is keeping greys in check between salon visits with a tone that stays subtle, this set of codes is aimed squarely at you.
How a single satchet is used
Each satchet holds one application. Work the colour through your hair, leave it for the time printed on the pack, then rinse until the water runs clear. The fixed portion removes the guesswork of mixing, which is part of why the satch format is friendly for home use.
Choosing your code
Start with the depth you want, then the finish. For the deepest, most coverage-focused result go for a higher number in BB, such as D-7 or D-8. For something a shade lighter consider D-4 / WB. If you prefer the WB family at a deep level, the Arias D-8 / WB is the one to compare against the BB codes.

FAQ
Frequently asked questions
What DEMI products are in this Deep Natural collection?
It gathers DEMI's Deep Natural self-dye satchets, including the Cover Hair Satch codes D-7 / BB, D-8 / BB and D-4 / WB, plus a satchet from the Arias Deep Natural line in D-8 / WB. All are single-application home hair colour.
What is the difference between BB and WB on these satchets?
BB and WB are DEMI finish families. The letter sits with the number to define the exact shade, so D-8 / BB and D-8 / WB share a depth but differ in finish. Matching the same letter you used before keeps results consistent.
How deep is each D-number?
Higher numbers go deeper. D-7 and D-8 are the deepest codes in this grouping, while D-4 lands lighter. Pick the number for the depth you want, then confirm the finish letter.
How do you use a DEMI Deep Natural satchet?
Apply the satchet through your hair, leave it for the time on the pack, then rinse until the water runs clear. Each satchet is one application, so there is no mixing or measuring.
Are these satchets for men or women?
Both. The packs are labelled for men and women, and the Deep Natural tones are designed to cover grey with a natural-looking finish for either.
