Hair Dye Syoss Oleo 2-10 Brown Black

Syoss Oleo 2-10 Brown Black is a permanent at‑home hair dye formulated to deliver a deep brown to near‑black shade with uniform coverage. The oil‑enriched formula aims to help pigments penetrate the hair shaft for long‑lasting color and consistent results when applied according to the instructions. It is intended to cover natural hair color and gray roots, producing an even, intense tone suitable for users seeking a dark, glossy finish.

Advantages

Its permanent formulation ensures extended color retention compared with temporary products. The product is suitable for standard developer‑based application, allowing controlled mixing and predictable results when directions are followed. The shade delivers a deep, near‑black appearance that hides grays and creates a cohesive color across lengths and roots.
