🎨 Cold, natural brown (4.15) · Ammonia-free permanent color · Oil-based ODS technology
Create a deep and sophisticated brown with cool reflections. This professional, ammonia-free permanent hair color from L'Oréal Professionnel Inoa is developed with the Oil Delivery System (ODS²), which uses oil to optimize color deposition and comfort. The shade 4.15 combines a medium brown base with a primary ash reflection and a subtle mahogany tone for a balanced, naturally cool result with shine.
Advantages
- Ammonia-free formula for minimal odor and high comfort during coloring.
- Oil-based ODS² technology that improves color penetration and preserves the hair's quality feel.
- Long-lasting, uniform color with a beautiful shine.
- High coverage on grey hair and an even result from root to tip.
- Professional precision in tone: cool, natural brown without excessive warmth.
Shade 4.15 – what to expect
- Medium brown base (level 4) with ash as primary reflex (1) rounded off by mahogany (5).
- Helps to tone down unwanted warm/orange tones for a more neutral, cool look.
- Suitable for those who want a deep, elegant brown with subtle dimension.
- A good choice for naturally brown or dark blonde hair – and when gray hair needs to be covered beautifully.
Result
A glossy, cool brown look with natural depth and movement. Hair feels well-groomed and looks healthy, while the color appears clean, uniform and true to tone.
