Estel Professional Princess Essex S-OS Illuminating Cream Hair Dye

Princess Essex S-OS (Special Only Blondes) is a specialized line of high-lifting, permanent cream hair dyes designed to lighten natural hair by up to 4 levels while simultaneously toning it in a single step. Housed in a 60 ml tube, this series is engineered specifically for non-bleached natural bases, offering a reliable path to clean, clear blonde shades without the use of aggressive bleaching powders.

Like the basic palette, S-OS incorporates the VIVANT SYSTEM—a protective blend of a Keratin Complex, Beeswax, and Guarana Seed Extract—to reinforce the hair matrix, seal the cuticle, and preserve natural elasticity during a high-lift process.

Purpose & Limitations

The S-OS series is a high-alkaline formula with a specific, targeted purpose. To achieve professional results, strict boundaries must be maintained:

Natural Bases Only: S-OS is designed exclusively for natural hair. It will not lighten previously colored hair, as artificial cosmetic pigment does not respond to high-lift tint.

Starting Level: For optimal, clean results, it is highly recommended to use S-OS on natural hair starting at a Level 7 (Medium Blonde) or lighter. It can be used on a Level 6 (Dark Blonde), but the resulting shade will be warmer.

Not for Gray Coverage: Due to its translucent, high-lifting nature, this series is not intended for covering gray hair.
