What is L’Oréal Majirel?

L’Oréal Majirel is a permanent hair color line known for delivering rich, deep, and long-lasting color results. It’s loved for its conditioning formula, a wide range of unique shades, and ability to cover grey hair flawlessly.
The Science Behind Majirel Hair Color
Majirel’s Core Technology: Ionène G™ and Incell™ - Majirel isn’t just about color—it’s about care. Ionène G and Incell molecules strengthen and protect the hair fiber during coloring, making the hair look smoother and shinier after every hair dye application. These molecules also contribute to a rich creamy texture during the mixing process, ensuring the mixture is properly prepared for optimal application and effective coverage.
Understanding the Color Numbering System
Majirel uses a 2-digit or 3-digit system:
-
The first number represents the depth (from 1 - black to 10 - lightest blonde).
-
The numbers after the decimal indicate tones (e.g., .3 = golden, .1 = ash, .6 = red).
So 6.1 = dark blonde ash. Pretty cool once you get the hang of it!
Before You Start Mixing

What You’ll Need
-
L’Oréal Majirel color tube (50ml)
-
L’Oréal Professionnel Cream Oxydant (developer) – 6%, 9%, or 12%
-
Non-metallic mixing bowl
-
Tint brush
-
Gloves
-
Timer
-
Old towel or cape
Remember, never skip the patch test, even if you’ve used color before. Mix a tiny amount and apply it behind your ear 48 hours prior to coloring. Better safe than sorry.
Choosing the Right Developer (Oxidant)
-
20 vol (6%) – standard for most color applications
-
30 vol (9%) – for lighter results
-
40 vol (12%) – use cautiously, mainly for majirel high-lift
How to Mix L’Oréal Majirel Color
The golden rule: 1:1.5 RatioThat means for every 1 part color (50ml), add 1.5 parts developer (75ml).
Mixing Instructions
-
Squeeze 1 full tube of Majirel into a non-metallic bowl.
-
Add 75ml of developer (based on your desired result).
-
Stir well using your tint brush until the majirel mix is smooth and creamy.
-
Use immediately. Don’t let it sit for too long.
For cool-toned, non-brassy results, consider using Majirel products enriched with cool reflects.
Mixing for Grey Coverage
For stubborn greys:
-
Use a half-and-half mix: ½ natural shade (e.g., 6.0) + ½ fashion shade (e.g., 6.3).
-
Stick with 20 vol developer for best grey coverage.
-
Don’t forget to saturate those greys well!
Adjusting Formula for Toning or Refreshing
For toning:
-
Use a 9 vol or 6 vol developer.
-
Mix 1:1.5 and apply to damp hair.
-
Process for 10-20 minutes max to avoid over-depositing.
Application Tips

Sectioning Hair Like a Pro
Split hair into four quadrants for even application:
-
Down the middle from forehead to nape.
-
Across the crown from ear to ear.
Clip them up and work methodically.
Applying Color Evenly
Start with the areas that need the most lift or coverage. Usually:
-
Roots first
-
Then lengths and ends
For optimal coverage, begin the application on dry, unwashed hair using a tint brush.
Use thin sections, saturate well, and avoid overlapping unless you’re refreshing.
Development Time Guidelines
-
35 minutes for standard coverage
-
Up to 45 minutes for resistant greys
-
15-20 minutes for toning on damp hair
Set a timer. Seriously, it matters.
Aftercare and Maintenance for Coloured Hair

First Rinse and Wash
Once the timer’s up:
-
Rinse hair thoroughly with lukewarm water.
-
Shampoo using a color-safe or post-color shampoo designed for coloured hair (like L’Oréal Professionnel Vitamino Color).
-
Follow up with a nourishing conditioner or mask.
Products to Use After Coloring
Stick to sulfate-free, color-safe shampoos and conditioners to prolong color vibrancy. Add a weekly deep treatment for hydration.
Avoid:
-
Hot water
-
Frequent washing
-
Heat styling without protection
Instead:
-
Use color-refreshing masks
-
Embrace dry hair shampoo
-
Wear a hat in the sun
Common Mistakes to Avoid

Mixing Too Early or Letting It Sit
Majirel mix starts oxidizing once prepared. Only mix what you’ll use immediately. No saving for later!
Using the Wrong Developer Strength
Don’t just grab any developer. Using the wrong volume can result in:
-
Underwhelming lift
-
Hot roots
-
Color banding
Overlapping on Previously Colored Hair
Unless you’re refreshing the ends of white hair with a diluted formula, avoid reapplying to the same sections each time. It can cause breakage and uneven color. For hair that is only slightly faded, adjust the application time to ensure the final color result is consistent and vibrant.
