Why I Love Loreal Cool Darkest Brown Hair Color

As someone with naturally dark brown hair, finding the perfect shade to dye my hair has always been a challenge. That’s why I swear by Loreal Cool Darkest Brown hair color. Not only does it give me the exact shade I’m looking for, but it also comes with a range of benefits that make it a must-have in my beauty routine.

First and foremost, the cool undertones in this shade help prevent any brassiness or red tones from showing up in my hair. This is especially important for dark-haired individuals like myself, as our natural hair color tends to pull warm tones. With Loreal Cool Darkest Brown, I can confidently rock my rich and cool-toned locks without worrying about any unwanted warmth.

In addition to its cool undertones, this hair color also provides excellent coverage for grays. As someone who has started to notice a few stray gray hairs, having a reliable and long-lasting coverage is crucial.

My Buying Guide on ‘Loreal Cool Darkest Brown’

As someone who loves to experiment with hair color, I have tried numerous brands and shades. Recently, I decided to go for a darker hair color and came across the ‘Loreal Cool Darkest Brown’ shade. After using it for a few months, I can confidently say that it is one of the best hair colors I have ever used. Here is my buying guide on ‘Loreal Cool Darkest Brown’ for anyone considering trying out this shade.

Understanding the Shade

Before purchasing any hair color, it is essential to understand the shade and its undertones. The ‘Loreal Cool Darkest Brown’ has a cool undertone, which means it has ashy or blue tones in it. This shade is perfect for those looking to achieve a deep, dark brown color without any red or warm tones.

Hair Type Compatibility

I have fine hair that tends to get dry easily, but this hair color worked well for me. However, it is always recommended to do a patch test before applying any hair dye to check for any allergic reactions or compatibility issues. Additionally, if you have thick or coarse hair, you may need to use more than one box of the Loreal Cool Darkest Brown to achieve full coverage.

Application Process

The application process of this hair color is straightforward and similar to other at-home dyes. The kit comes with everything you need – developer, colorant, conditioner, gloves, and instructions. I found the instructions easy to follow and had no issues while applying the dye. The formula also has a pleasant scent compared to other dyes I have used in the past.

Results and Longevity

After using this hair color, my hair was left looking shiny and healthy with an intense dark brown hue. The cool undertones were prominent in natural light and gave my hair a unique depth of color. As for longevity, the dye lasted around six weeks before fading slightly. However, using sulfate-free shampoos can help prolong the color’s vibrancy.

Tips for Maintenance

To maintain the ‘Loreal Cool Darkest Brown’ shade’s vibrancy and shine, I recommend using a color-safe shampoo and conditioner specifically formulated for dark hair colors. It is also essential to avoid excessive heat styling as it can cause the dye to fade faster.

Final Thoughts

Overall, I highly recommend trying out ‘Loreal Cool Darkest Brown’ if you are looking for a rich dark brown shade with cool undertones. It provides excellent coverage even on gray hairs without leaving any brassy tones behind. Just make sure to follow all instructions carefully and perform regular maintenance for long-lasting results.

In conclusion, after trying out numerous shades from different brands over the years, Loreal’s Cool Darkest Brown has become my go-to choice for achieving a deep dark brown look with cool undertones. I hope this buying guide helps anyone considering trying out this shade make an informed decision.
