The Ultimate Buying Guide for Blue Black Hair Dye
Thinking about diving into the deep, mysterious world of blue black hair dye? This color is stunning. It looks black in low light but flashes brilliant blue in the sun. Choosing the right dye makes all the difference. This guide helps you pick the best product for your hair goals.
Key Features to Look For
When shopping for blue black dye, look closely at these important features. They tell you a lot about the dye’s performance and safety.
1. Color Intensity and Tone
- True Blue Black: Check reviews to see if the final color is truly blue-based black, or if it leans too purple or dark brown.
- Fade Resistance: Good dyes resist fading quickly. Look for terms like “long-lasting” or “fade-defying.”
2. Dye Type
- Permanent Dye: This option offers the deepest color payoff and lasts until your hair grows out or you color over it. It usually requires developer.
- Semi-Permanent/Direct Dye: These deposit color on top of the hair shaft. They wash out faster but are gentler on your hair.
3. Conditioners and Additives
- A high-quality dye includes nourishing ingredients. Look for natural oils (like coconut or argan) or proteins (like keratin). These keep your hair soft during the chemical process.
Important Materials in Your Dye Kit
What’s inside the box matters a lot. Always check the ingredient list.
Developer (For Permanent Dyes)
Developers contain hydrogen peroxide. They lift your natural color slightly so the blue black pigment can enter the hair shaft. The volume (e.g., 20V, 30V) determines how much lift you get. Lower volumes are less damaging.
Color Pigments
The actual blue and black pigments create the shade. High-quality synthetic pigments provide vibrant, true-to-box results. Natural dyes might use ingredients like indigo, but these often result in a softer blue black.
Protective Gear
A good kit provides gloves and sometimes a protective cap or barrier cream. Never skip using the provided gloves!
Factors That Improve or Reduce Quality
Not all blue black dyes perform the same. Some factors seriously impact the final look and health of your hair.
Factors That Improve Quality:
- Low Ammonia Content: Dyes with less ammonia smell better and cause less cuticle damage.
- Pre-Lightening Recommendation: If you have very dark hair, the dye package should suggest if you need to lighten (bleach) your hair first for the best blue reflection.
- Positive User Reviews: Real user photos are the best quality check.
Factors That Reduce Quality:
- High PPD Levels: PPD (para-phenylenediamine) is a common dye chemical. High levels can cause allergic reactions or harshness, though it helps color stick.
- Drying Ingredients: If the ingredient list is full of harsh alcohols, the dye will leave your hair feeling brittle.
User Experience and Use Cases
Think about why you want this color and how you plan to use the dye.
For Beginners:
New users should choose semi-permanent dyes or kits specifically labeled “easy application.” These often come in a single-step cream format. They offer a lower risk if you make a small mistake.
For Covering Gray Hair:
If you are covering significant gray, you must use a permanent dye. Gray hair lacks pigment, so it needs the developer to open the cuticle and deposit the color fully. Look for dyes rated for 100% gray coverage.
Maintenance:
Blue tones fade fast! Good user experiences involve using color-safe, sulfate-free shampoos. You might need a blue-black color depositing conditioner every few weeks to keep the vibrancy alive.
10 Frequently Asked Questions (FAQ) About Blue Black Hair Dye
Q: Will blue black dye look black on my dark brown hair?
A: Yes, it often will. The blue tint is usually only visible in direct sunlight or bright light. On very dark hair, it looks like a deep, rich black.
Q: Do I need to bleach my hair first?
A: If your hair is naturally dark brown or black, you probably do not need to bleach it. If you want a very bright, noticeable blue flash, lifting your hair to a dark brown or medium brown level first helps the blue show up better.
Q: How long does blue black dye usually last?
A: Permanent dye lasts about 6 to 8 weeks before noticeable root regrowth. Semi-permanent dye washes out significantly within 4 to 12 washes.
Q: Can I use blue black dye over previously dyed hair?
A: You can often apply it over old dark color. However, if the old color is red or orange, the blue black might turn muddy or green. Always strand test first!
Q: Does blue black hair dye stain skin and clothes easily?
A: Yes, blue and black pigments are notorious stainers. Wear old clothes and use petroleum jelly around your hairline before applying.
Q: Is this color difficult to switch away from later?
A: Blue black is one of the hardest colors to remove because black pigments are very strong. You will likely need color remover or bleach to lift it later.
Q: What is the best shampoo to use after dyeing?
A: Use shampoos labeled “color-safe” and “sulfate-free.” Sulfates strip color out very quickly.
Q: Should I buy a box dye or go to a salon?
A: Box dye is cheaper and faster for all-over color change. A salon offers better control, especially if you are going from a very light color to blue black.
Q: Why does my blue black look purple instead of blue?
A: This happens if your natural base color had too much red or if the dye formula leans warm. Using a developer helps push the color more accurately.
Q: Are there any allergy concerns with this dye?
A: Always perform a patch test 48 hours before coloring. This checks for reactions to ingredients like PPD, which are common in dark permanent dyes.
