Free Plant-Based Coloring Guide
Real Earth · Free guide
Your color, your gray hair,
your plant-based guide.
We have spent years supporting women in their transition to more natural coloring, and there is one question we hear week after week:
"With my gray hair... which shade will suit me best?"
That is why we have created our Ultimate Plant-Based Coloring Guides: a guide for every shade, with everything you need to know to get it right the first time, without surprises.
For now, we have the Brunette Guide and the Blonde Guide available (and very soon, the Redhead Guide!).
