The Ultimate Buying Guide for Blue Black Hair Colour
Choosing the right blue black hair colour can transform your look. This deep, mysterious shade combines the richness of black with cool blue undertones. To help you find the best product, we break down what you need to know before you buy.
Key Features to Look For
When shopping, look closely at the product label. Certain features make a dye better than others.
1. Colour Intensity and Tone
- Depth: A good blue black should look almost black in low light but reveal deep blue highlights in the sun. Avoid shades that look simply grey or dull.
- Blue Shift: Check reviews to see how strong the blue undertone is. Some dyes lean more towards navy, while others offer a subtle, cool reflection.
2. Longevity and Fade Resistance
- Permanent vs. Semi-Permanent: Permanent dyes last until your hair grows out. Semi-permanent colours fade over several washes. Decide how long you want the colour to stay.
- Fade Pattern: The best colours fade gracefully. Poor quality dyes often turn brassy or greenish as they wash out. Look for products that fade to a deep indigo or charcoal.
3. Conditioning and Shine
- The dye should leave your hair feeling soft, not brittle. High-quality formulas include conditioning agents.
- Look for words like “high shine,” “glossy,” or “moisturizing” on the box.
Important Materials to Check
The ingredients list tells you a lot about the dye’s quality and how it will affect your hair.
1. Ammonia Content
- Traditional dyes use ammonia to open the hair cuticle. This allows the colour pigment to enter deeply. However, ammonia can be harsh.
- Low-Ammonia or Ammonia-Free options are gentler on the scalp and hair shaft. These are better for frequent touch-ups.
2. Conditioning Agents
These ingredients protect your hair during the colouring process. Good examples include:
- Natural oils (like Argan or Coconut oil).
- Keratin or proteins.
- Panthenol (Vitamin B5).
3. Developer Strength (For Lift/Lightening)
If you have very dark hair, you might need a developer to lift your natural colour slightly for the blue to show. Higher volume developers (like 30 or 40) lift more but cause more damage. Developers around 10 or 20 are usually safer for depositing colour onto dark bases.
Factors That Improve or Reduce Quality
What makes one blue black dye superior to another?
Quality Boosters:
- Included Aftercare: A quality kit provides a colour-sealing conditioner or mask. Use this! It locks the colour in.
- Even Pigment Distribution: The dye should spread easily without clumping. This ensures no patchy spots.
Quality Reducers:
- Strong Chemical Smell: A very strong, acrid smell often means high levels of harsh chemicals.
- Lack of Instructions: Confusing or vague instructions suggest a less professional formula.
User Experience and Use Cases
How you plan to use the colour affects your purchase decision.
For Dark Hair Users:
If your hair is naturally black or dark brown, you need a dye formulated to deposit pigment heavily. These often require a longer processing time to achieve the visible blue tone.
For Light Hair Users:
If your hair is pre-lightened, the blue black will look much brighter and more vibrant. You might choose a semi-permanent toner for a less committed look.
Allergy Testing:
Always perform a patch test 48 hours before colouring. This prevents allergic reactions, which greatly reduce the user experience!
10 Frequently Asked Questions (FAQ) About Blue Black Hair Colour
Q: Will blue black hair dye work on my natural black hair?
A: Yes, it will work. It will add a visible blue sheen or tint, especially in sunlight. It usually won’t lighten your hair significantly.
Q: How long does blue black dye usually last?
A: Permanent dyes last about 6 to 8 weeks. Semi-permanent dyes usually last 4 to 12 washes, depending on how often you shampoo.
Q: Does blue black fade to a weird colour?
A: High-quality dyes fade to a deep indigo or charcoal grey. Lower quality dyes sometimes fade to a greenish or dull purple shade.
Q: Do I need to bleach my hair first?
A: You only need to bleach if your natural hair is medium brown or lighter and you want a very bright blue-black. For most dark-haired people, bleaching is not necessary.
Q: Is blue black hair dye difficult to cover up later?
A: Yes, blue and black pigments are very strong. Covering blue black with lighter colours, like blonde, requires professional colour removal or multiple bleaching sessions.
Q: What shampoo should I use to keep the colour vibrant?
A: Use shampoos made for colour-treated hair. Look for sulfate-free formulas, as sulfates strip colour faster.
Q: Can I mix blue black with natural black dye?
A: Yes. Mixing them can help you achieve a custom shade that is slightly less intense than pure blue black, making the transition softer.
Q: Will this dye stain my towel or pillowcase?
A: Freshly dyed hair releases some colour, especially when wet. Use an old, dark towel for the first few washes, and consider wearing a dark pillowcase initially.
Q: Is blue black suitable for grey or white hair?
A: Grey hair absorbs colour quickly. If you use a permanent dye, the grey areas might turn very blue. You may need to mix the dye with a neutral colour first.
Q: What is the difference between “blue black” and “jet black with blue undertones”?
A: “Blue black” implies a noticeable, deep blue reflection. “Jet black with blue undertones” is much closer to pure black, showing only a slight cool tint under direct light.
