When it comes to achieving a stunning, deep blue-black hair color that turns heads and lasts, few products can match the Rusk Deepshine 1.10BB Intense Blue Black. This professional-grade permanent hair color has earned a loyal following among both salon professionals and at-home color enthusiasts — and for good reason. In this guide, we'll explore everything you need to know about this iconic shade, from its formulation and application to aftercare tips and who it's best suited for.
What Is Rusk Deepshine 1.10BB Intense Blue Black?
Rusk Deepshine is a professional permanent hair color line renowned for its superior gray coverage, vibrant tones, and conditioning properties. The shade 1.10BB — Intense Blue Black is one of the most dramatic and striking shades in the entire collection. The "1" indicates it sits at the very darkest end of the color spectrum (Level 1), while "BB" signals a double blue base — meaning the pigment is heavily loaded with blue tones for an intensely cool, almost blue-tinted black finish.
This shade is not your average black. It has a luminous, almost metallic quality that catches light beautifully, giving the hair a multidimensional depth that flat blacks simply cannot achieve. Think of it as black hair with a soul — the kind of color you see in glossy editorial spreads or on the silver screen.
Key Features and Benefits
1. Intense, Saturated Pigment
The double blue base (BB) in 1.10BB means the formula is packed with concentrated blue pigment. This results in a vivid, cool-toned black that avoids the brassy or red undertones that plague many dark permanent colors. If you've ever colored your hair black only to see warm, reddish hues in sunlight, Rusk Deepshine 1.10BB is designed to solve exactly that problem.
2. Professional-Grade Permanent Formula
Unlike semi-permanent or demi-permanent options, Deepshine 1.10BB is a full permanent color. This means it penetrates the hair cortex deeply, offering long-lasting results that don't simply wash away. For those seeking a committed, bold color change, permanent color is the gold standard — and Rusk's formula is among the best in the industry.
3. Excellent Gray Coverage
One of the standout attributes of the Rusk Deepshine line is its exceptional gray coverage. The 1.10BB shade delivers up to 100% gray coverage, making it an excellent choice for those looking to conceal grays while achieving a rich, youthful-looking black. The blue-black tone helps mask the natural warmth of gray hair, resulting in a seamless, uniform finish.
4. Conditioning and Nourishing Formula
Hair color can be damaging if not formulated with hair health in mind. Rusk Deepshine addresses this concern with a formula enriched with silk and keratin proteins, which help to strengthen, smooth, and protect the hair during the coloring process. Many users report that their hair feels noticeably softer and shinier after using Deepshine compared to other permanent color brands.
5. Low Ammonia Formula
Rusk Deepshine uses a low-ammonia formulation, which means less harsh smell during application and less potential for irritation. This is a major advantage for clients who are sensitive to the strong chemical odors often associated with permanent hair color.
Who Is Rusk Deepshine 1.10BB Best Suited For?
This shade is ideal for a wide range of people, but it's particularly well-suited for:
- Natural brunettes and those with dark hair looking to deepen or enrich their existing color with a cool-toned black.
- Gray coverage seekers who want a bold, youthful transformation without brassy undertones.
- Bold color enthusiasts who love the dramatic aesthetic of blue-black hair — a look popularized in goth, punk, and high-fashion circles alike.
- Those transitioning from lighter shades who want a complete color overhaul with maximum impact.
It's worth noting that because this is a Level 1 shade, it is not recommended for those looking to go lighter afterward without a significant color correction process. Going darker is always easier than going lighter, so commit to this shade knowing it will require professional assistance to reverse.
How to Apply Rusk Deepshine 1.10BB
For best results, Rusk Deepshine is typically used with a 20-volume developer for standard applications, though a 10-volume developer can be used for maximum gray coverage and deposit. Here's a general application guide:
- Prepare your tools: Mix one part Deepshine 1.10BB color with one and a half parts developer in a non-metallic bowl.
- Section the hair: Divide hair into four sections for even application.
- Apply to roots first if doing a retouch, or work from roots to ends for a full-color application.
- Process for 30–45 minutes at room temperature, checking periodically.
- Rinse thoroughly with lukewarm water until the water runs clear, then shampoo and condition.
Always perform a strand test and a skin allergy test 48 hours before full application. If you're new to at-home color or working with previously color-treated hair, consulting a professional is always recommended.
Aftercare: Keeping Your Blue-Black Color Vibrant
Maintaining the intensity of a blue-black shade requires some dedicated aftercare. Blue pigments, while stunning, can be among the first to fade — especially with frequent washing or sun exposure. Here are some tips to keep your color looking its best:
- Use a color-safe, sulfate-free shampoo. Sulfates strip color faster than almost anything else. Opt for a gentle, color-protecting formula.
- Wash in cool water. Hot water opens the hair cuticle, causing color molecules to escape. Cooler water helps seal the cuticle and preserve color.
- Limit washing frequency. The less you wash, the longer your color will last. Aim for every 2–3 days, or use dry shampoo between washes.
- Use a blue or purple toning conditioner occasionally to refresh the cool tones and counteract any warmth that creeps in over time.
- Protect hair from UV exposure. The sun can fade color rapidly. Use a UV-protectant hair spray or wear a hat when spending extended time outdoors.
- Deep condition regularly. Permanent color, even with a conditioning formula like Deepshine, can cause some dryness over time. A weekly deep conditioning mask helps maintain softness and shine.
Why Choose Rusk Deepshine Over Other Black Hair Colors?
The market is flooded with black hair color options, so what makes Rusk Deepshine 1.10BB stand out? The answer lies in the combination of pigment intensity, hair health focus, and professional-quality results. Many drugstore black dyes fade to warm, muddy tones within weeks. Deepshine, by contrast, maintains its cool, blue-toned depth significantly longer thanks to its concentrated pigment load and quality formula.
Additionally, the silk and keratin proteins in the formula mean that hair doesn't just look great immediately after coloring — it continues to look and feel healthy in the weeks that follow. For those who have experienced the dry, brittle aftermath of cheap box dyes, this is a game-changer.
Final Thoughts
Rusk Deepshine 1.10BB Intense Blue Black is more than just a hair color — it's a statement. It's bold, beautiful, and backed by a professional-grade formula that delivers results you can see and feel. Whether you're a salon professional looking for a reliable go-to black shade or an at-home colorist ready to take the plunge into dramatic, blue-toned black hair, this product deserves a place in your color toolkit.
With proper application and aftercare, Rusk Deepshine 1.10BB can give you the kind of luminous, multidimensional black hair that looks like it belongs on a magazine cover. Give it a try — your hair will thank you.
