What makes the Dark Mahogany 5.5 shade different from a standard dark brown?

Dark Mahogany 5.5 is a warm brown-red nuance that catches light without looking overly bright, giving a richer, more expressive result than flat dark shades.

How do the rice protein and the keratin fixing balm change the colour outcome and hair feel?

Rice protein helps pigments bind more evenly for a fuller, brighter shade, while the post-colour keratin balm smooths the cuticle for a sleeker, glossier finish.

I have a sensitive scalp and previously coloured hair — what precautions should I take?

Do a patch test 48 hours before, follow the timing exactly, and consider applying a barrier cream or skipping the scalp area if your lengths are heavily processed.

Will this cover my grey hair completely, and how does the mahogany reflect behave on white strands?

Yes, the 5.5 level is designed for grey blending; on white hair the mahogany reflect gives a warm, translucent highlight rather than a flat opaque block.

Dark Mahogany

The long-lasting creamy hair color Rubella Fashion Color enhances the optical effect of hair color.

The rice protein in its formula helps retain more color pigments in the hair, making the hair color more vibrant and shiny. The fixing balm is enriched with a complex of vitamins and keratin, providing deep and long-lasting nourishment. Keratin is one of the key building components in hair structure, helping to strengthen and straighten the hair. The result is lively hair with intense color.

How to use?

Mix the dye with the developer and apply it to the hair. Leave it on for 30 minutes, then rinse thoroughly with warm water. Finish by applying the balm.

Important: Perform an allergy/sensitivity test before use!

What it is

Rubella Beauty RUBELLA Fashion Hair Color Dark Mahogany 5.5 is a permanent cream hair dye for those who want a deep mahogany tone with visible shine, not just a flat dark shade. People usually choose this type of color when they want a richer result, better grey blending, or a refreshed look that stays expressive after washing.

Key components

What makes this formula interesting is the combination of coloring performance with conditioning ingredients:

Rice protein helps the hair hold on to more color pigments, which can make the shade look fuller, brighter and more even. In simple terms, it helps the color settle better along the hair fibre, so the finished result appears more vivid.
Fixing balm with keratin and vitamins is applied after coloring. Keratin is a protein naturally present in hair, and in hair cosmetics it is used to smooth the surface of the strand, reduce a rough feel and leave the lengths looking sleeker and glossier.

When people choose it

This is especially useful in several situations:

For hair that tends to feel dry after coloring, or lengths that look dull.
For anyone who wants the shade and finish to look polished rather than harsh.
For easier at-home application, since a creamy hair color is often easier to distribute through the hair than thinner formulas, helping with a more uniform result.

The Dark Mahogany 5.5 tone suits those who like a warm, elegant brown-red nuance that catches the light without looking overly bright. Rubella Beauty hair colouring products are best suited to people who want lasting color together with a smoother after-feel. It can fit well before an event, when refreshing faded lengths, or when updating the overall tone between salon visits.

Important notes

As with any oxidative hair dye, it is wise to use it carefully:

Always do the allergy test in advance.
Follow the instructions exactly.
Be extra cautious if your scalp is sensitive or your hair is already heavily processed.

Customer Questions

The 5.5 tone is a specific depth-and-reflect code: the "5" indicates a medium-dark brown base, while the ".5" signals a mahogany (red-violet) reflect. In practice this means the colour reads as a deep, warm brown in low light but reveals a subtle red-brown shimmer when light hits it, rather than appearing as a single flat dark shade. This reflect helps the colour look alive after multiple washes, because the mahogany pigments fade more gracefully than pure ash or neutral tones, which can turn dull or greenish over time. If you have previously used a level 4 or 5 neutral brown and found it too "heavy" or one-dimensional, 5.5 adds warmth and dimension without lifting to a bright copper. It also blends grey more naturally on warm skin tones, since the red-violet reflect mimics the warmth that natural pigment provides. The result is described as polished rather than harsh, which is useful if you want the colour to look intentional rather than like a uniform block of dye.

Rice protein is a film-forming, hydrolysed protein that deposits on the hair shaft during the colouring process. Because it has an affinity for both the keratin in hair and the oxidative dye molecules, it creates a more uniform surface for the pigments to latch onto. The practical effect is that the colour develops more evenly from root to tip, reducing patchiness — especially on porous ends — and the final shade appears more saturated and luminous rather than muted. After rinsing the colour, the included fixing balm delivers keratin and vitamins directly to the freshly coloured hair. Keratin fills microscopic gaps in the cuticle lifted by the alkaline developer, so the hair surface feels smoother and reflects light more uniformly, which reads as gloss. The vitamins (typically panthenol and vitamin E derivatives in such balms) add humectant and antioxidant support, helping the hair retain moisture and reducing the rough, straw-like texture that often follows permanent colour. Used together, these two steps mean you get both the depth of a permanent dye and a conditioned finish that usually requires a separate mask or salon treatment.

Because this is an oxidative permanent dye (it uses an alkaline agent and hydrogen peroxide to open the cuticle and develop colour), the scalp is exposed to potential irritants like ammonia substitutes, resorcinol, and p-phenylenediamine derivatives. The manufacturer explicitly advises an allergy alert test 48 hours before each use — even if you have used the brand before — because sensitisation can develop at any time. Apply a small amount behind the ear or on the inner forearm, leave uncovered, and watch for redness, itching, or swelling. If your scalp is already sensitive, protect it by applying a thin layer of petroleum jelly or a dedicated scalp barrier cream along the hairline and partings before mixing the colour. For previously heavily processed lengths (bleached, permed, or repeatedly coloured), the cuticle is more open and will grab pigment faster and darker. To avoid overly dark, brittle ends, you can either apply the mixture to roots first and pull through only the last 5–10 minutes, or dilute the developer for the lengths with a conditioner (1:1) if the instructions allow. Always respect the maximum development time printed in the leaflet; extending it will not deepen the shade but will increase damage and irritation risk.

Permanent cream dyes at level 5 with a .5 reflect are formulated to deposit enough pigment to cover resistant white hair while the mahogany tone prevents the "helmet" effect of a solid dark brown. On 100% white strands the colour will take true to the swatch — a warm, red-brown that reads as a natural-looking depth with a subtle glow. On salt-and-pepper hair the already-pigmented strands will shift slightly warmer and darker, while the white strands become the brightest points, creating a natural-looking highlight pattern. If you have more than 70% white hair and want a completely uniform result, you may need to pre-pigment (apply a warm copper or gold demi-permanent first) or choose a neutral/natural series (e.g., 5.0) for the root area and use 5.5 only on the lengths. The creamy consistency helps here because it clings to the hair rather than dripping, giving you more control to saturate resistant grey at the hairline and temples. Re-growth touch-ups every 4–6 weeks will keep the blend seamless; the mahogany reflect fades to a warm caramel rather than an ashy green, so the line of demarcation stays softer between salon visits.
