My Buying Guides on Black Onyx Hair Color

When I decided to switch up my hair color, I was drawn to the rich and mysterious allure of Black Onyx. This deep, dark hue not only adds a touch of sophistication but also complements various skin tones beautifully. If you’re considering this shade, here’s my personal buying guide to help you make the best choice!

Understanding Black Onyx Hair Color

Before diving into products, it’s essential to understand what Black Onyx hair color really is. It’s a deep black with subtle hints of blue or violet undertones, giving it a luxurious and multi-dimensional look. I found that this color can vary from a pure jet black to a softer, more muted black, depending on the brand and formulation.

Choosing the Right Product

When I was looking for the perfect Black Onyx hair color, I discovered various types of products available:

  1. Permanent Hair Dyes: These are ideal if you want a long-lasting color change. I opted for a permanent dye for my transformation, as I wanted the color to stay vibrant for months.
  1. Semi-Permanent Dyes: If you’re unsure about committing to a permanent change, semi-permanent dyes are a great option. I tried a semi-permanent formula first to see how I liked the color before making a long-term decision.
  1. Temporary Hair Colors: For a short-term switch, temporary colors can be fun. I used temporary sprays for a night out, which allowed me to enjoy the Black Onyx shade without commitment.

Application Process

One of the most crucial aspects of achieving that perfect Black Onyx shade is the application process. Here’s what I learned:

  • Preparation: Always read the instructions thoroughly. I made sure to do a patch test to avoid any allergic reactions.
  • Tools: I gathered all necessary tools, including gloves, an applicator brush, and a mixing bowl. Having everything ready made the process smoother.
  • Sectioning: I found that sectioning my hair into manageable parts helped ensure even application. This was key to achieving that rich, uniform color.

Aftercare Tips

Once I achieved my desired Black Onyx hue, I realized that maintaining the color is just as important as the initial application. Here are my go-to tips:

  • Use Color-Safe Shampoo and Conditioner: I switched to sulfate-free products designed for color-treated hair. This helped preserve my color longer.
  • Limit Heat Styling: I noticed that reducing my use of heat styling tools kept my hair healthier and the color more vibrant.
  • Regular Touch-Ups: Depending on my hair growth, I schedule touch-ups every 4-6 weeks to keep the color looking fresh.

Where to Buy

I found a variety of places to purchase Black Onyx hair color:

  • Beauty Supply Stores: These often have a wide selection, and I appreciated being able to consult with staff for recommendations.
