A sophisticated brown shade that combines cool ash with a subtle hint of mahogany for a natural, well-balanced result. The formula is ammonia-free and utilizes an oil-based technology that helps the color pigments penetrate deep into the hair fiber, leaving hair soft with a beautiful, mirror-like shine.
The shade 5.15 in brief
- Level 5: light brown
- Primary reflex .1: ash – helps to tone down warm/orange tones
- Secondary reflex .5: mahogany – adds depth and easy play
Advantages
- Ammonia-free for better comfort and a more odor-neutral experience
- Oil-powered ODS² technology for even penetration and beautiful shine
- Long-lasting, uniform color with natural-looking finish
- Up to 3 levels of lightening and up to 100% coverage of gray hair

Result
