After doing much research about alternative hair color products, I came across a few you may be interested in!
Herbe Color, based out of Italy is the oldest color company dedicated to being environmentally safe and safe for us and our clients. Marie is a lovely woman and can answer all questions and send you a brochure about the products. You can reach Marie at #1.866.966.0366.
The color leaves the hair in impeccable condition, and has no smell when processing!!! I highly reccomend this line.
Their is another lline called Colour Herbe that has a technical manual you can download to read about vegetable based products and how they work. They also have Clay Based Lightners (instead of Bleach) you can try as well. the Baliage technique works well with there products:)....Have fun!!!
