  1. Good Afternoon

    I would like to know when your company will start introducing grey silver colours. I love your hair dyes but would love to see grey silver colours added to your brand. Can you please let me know if or when grey silver shades will be introduced.

    Thank you
    Happy Customer

    • Hi,
      Thank you for your nice words and delighted to hear that you are happy with Color & Soin Hair colors. Producing ammonia free hair colors is more difficult than producing regular colors, that is why the number of different shades are less in this range. At the time being there are only 34 shades available, and unfortunately grey silver is not in between them. Sorry 😢😢
