Flawless Grey Coverage with Better-Than-Ever Texture.

Long hair is prone to dryness and breakage after coloring. OiN’s herbal essence works with our exclusive repair treatment to penetrate deep into the hair shaft, restoring damaged cuticles. Our results prove it: hair stays tangle-free with a silky, weighted drape and a signature "Angel Halo" shine.

Expert Care Tip: Unlike traditional chemical dyes, natural herbal hair dye does not have a fixed color code. Because the ingredients are 100% natural, the final shade subtly varies based on your grey hair ratio, hair texture, and condition. This "Color & Care" synergy produces a multi-dimensional, highlight-like effect, ensuring a unique, healthy radiance exclusive to every client.

Everything You Need to Know About

OiN Hair Herbal Hair Coloring.

  • OiN Hair’s herbal formula is STC-certified and free from PPD, ammonia, and heavy metals. For those with a history of herbal allergies, we perform a patch test before the treatment to ensure complete safety throughout the process.

  • While natural herbs cannot produce neon or high-intensity colors, our 20 years of experience allow us to blend elegant, sophisticated shades such as "Warm Wood Caramel," "Deep Elegant Coffee," and "Natural Soft Black" to enhance your personal style while covering grey.

  • Yes, you can see immediate results after a single treatment. However, the final outcome varies depending on your grey hair percentage, hair texture, and damage level, creating a unique and healthy radiance for every individual.

  • Natural herbal dyes form a protective coloring layer on the hair surface without damaging the cuticles. Therefore, the color will evolve naturally with each wash. We recommend following our daily care tips to lock in nutrients for longer-lasting results.

  • Since natural ingredients require time to penetrate the hair, the entire treatment takes about 2 hours. We suggest allowing enough time to enjoy this relaxing herbal therapy in our comfortable environment.

  • Yes. OiN Hair uses a gentle, 100% natural formula free from synthetic chemicals. It is safe for those suffering from eczema or hair loss, as well as for pregnant and nursing mothers.
    ➡️ Natural Scalp Care

  • You can identify them through these three points:

    1. Strong Odor: Chemical dyes often contain ammonia, which has a pungent smell and can cause stinging sensations or permanent cuticle damage.

    2. Artificial Longevity: Chemicals use PPD to lock pigments inside the hair shaft, resulting in a stiff, dull color that never fades.

    3. Excessive Variety: Pure herbs cannot produce neon shades. If there are many vibrant or "neon" options, synthetic dyes have likely been added.

    1. Strong Odor: Pungent ammonia smell or scalp stinging; damages hair cuticles.

    2. Locked Color: Uses PPD to lock dye inside the hair shaft; looks stiff and never fades.

    3. Neon Shades: Pure herbs can't produce neon tints. Vibrant colors mean synthetic additives.
