dying cattle

Need advice on what would be the best dying techniques out there and what are the best products
Thanks

If you do a search you will find many threads on this

save your money, go to walmart and buy the cheapest (if im not mistaken its and orange kind of brown box) Ammonia free Black people hair dye and a pair of like kitchen gloves that you wash dishes with, mix it up and get to work let set 20 minutes and wash out and use the conditioner stuff in the boxes rub it on them, kind of lightly spray water on them masage it in again then wash out

We used a revlon product last year.  Our cattle are black and I see you have shorthorn in your name so dont know if the black will work  but it worked awesome for us.  We have done this a few times and has worked great every time!!  Good luck!!
