Cruelty Free Hair Dye for coloring a virgin hair extensions

Hi guys, nice to meet you all I am new here Looking for to get some in formations about cruelty free hair dye. I am a hair extensions stylist from Ireland (originally from Poland ) I have a goal to create my own best quality hair extensions line and I have already everything except hair dye. I was wondering if any of you guys could help me sourcing a cruelty free hair dye producers .Maybe some young company that is new on the market I know that Kevin Murphy is a cruelty free but the products are way too thick to dye large quantities of hair, and the price range is a bit too high to purchase a products to dye for example 10 kg of hair Other companies I found having too small color range, or for example only "crazy" colors I'm looking to start with 13-15 colors including least 5 blondes... I was looking over the internet for some info and I found your forum. I would very much appreciate your help if you came across anything that would help me:)
