Understanding Inoa Hair Color

If you’re looking for a permanent hair color that’s gentle on your strands, Inoa hair color might just be the perfect pick. It’s ammonia-free and uses a breakthrough Oil Delivery System (ODS technology) — a game-changer for maintaining hair health throughout the coloring process. Unlike traditional hair dye, Inoa’s innovative formula delivers vibrant, long-lasting color without the harsh effects.
Thanks to its oil base, Inoa leaves hair feeling smooth and hydrated while protecting the hair cuticle, helping prevent uneven color and dull texture. It’s great for nearly every hair type and offers a wide range of shades, whether you’re going bold or subtle.
If you have sensitive skin or a delicate scalp, this ammonia-free permanent hair color is ideal. It's specifically formulated for comfort and quality results. Inoa also addresses common hair coloring concerns such as damage, dryness, scalp irritation, and color fading, providing a gentler and more nourishing alternative to other options.
What Makes the Oil Delivery System Special
The ODS technology in Inoa works differently from traditional hair colour. The key difference is that, instead of relying on ammonia, Inoa uses an oil-based delivery system that gently opens the cuticle so the pigment can penetrate, reducing the risk of irritation or damage.
This leads to glossy, vibrant color and soft, shiny hair that feels as good as it looks. Inoa's system can also enhance hair vibrancy, shine, and overall quality, providing a healthier and more radiant appearance. It also helps develop a more consistent mixture, which minimizes the chance of uneven color or fading — perfect for those who want optimal results.
Choosing the Right Developer

The right Inoa developer determines how well the color takes, how long it lasts, and how your hair feels afterward. Inoa developers are peroxide solutions, and their concentration directly affects color processing, lift, and deposit. Using the wrong type increases the risk of irritation, uneven results, or even a mismatch in shade.
Choosing the correct developer and mixing ratio is crucial for achieving vibrant and long-lasting results. The Inoa developer is specifically paired with Inoa hair color for best compatibility and results. Inoa developers are crafted to work exclusively with Inoa hair color, and they come in various volumes to suit your desired lift, coverage, and texture. Picking the correct mixing ratio for your preferred result is essential.
Here’s a quick guide to help you match the developer to your goal:
-
10 Vol – Deposit Only: Best for darkening or doing tone-on-tone color. Also great for refreshing faded ends without over-processing.
-
20 Vol – One Level Lift: Ideal for gray coverage or lightening your natural hair colour by just one level.
-
30 Vol – Up to Two Levels Lift: Perfect for a more noticeable lift, especially if you’re going lighter on virgin hair.
Application & Processing
Learning how to mix L’Oreal Inoa hair color with developer properly is key. Here’s a simple step-by-step guide to help you apply it like a pro — safely, effectively, and with beautiful results.
Step-by-Step Mixing Instructions
-
Wear protective gear - Gloves and cape on — protect your skin, clothing, and workspace.
-
Measure precisely - Use a scale: 60g of Inoa + 60g of developer (1:1 ratio) for consistent results.
Tip: For lighter shades or gentler processing, you can use half the amount of developer or color. Adjusting the ratio, such as mixing half parts, will affect the final outcome. -
Mix until smooth - Blend to a yogurt-like texture. A bowl or shaker helps achieve a lump-free mixture.
-
Apply immediately - The formula works best when fresh. Leave it on for 35 minutes. Rinse, then wash and condition thoroughly.
Tip: Always experiment with a strand test or small batch before full application to find your ideal shade and formula.
⚠️Always follow official instructions. Wear gloves, check processing time, and use tools like a brush or bottle for accurate application.⚠️

Maintenance & Aftercare
Once you’ve colored your hair with Inoa, a little extra care goes a long way! To keep your color fresh and your strands healthy, it’s important to follow a proper aftercare routine.

Go sulfate-free - Always reach for sulfate-free hair products. They’re much gentler on colored hair and help preserve your shade for longer.
-
Hydration is key - Regular conditioning and moisturizing treatments can keep your hair soft, smooth, and full of life, and help prevent fading or dryness.

Turn down the heat - Try to avoid hot water and heat styling tools, as they can strip color and dry out your hair. When doing heat styling, use a heat protectant.
