This product is very effective and gives a good even colour. The only problem is that 72 hours later my hair still smells like wet hay. I am going to try adding a bit of essential oil the next time I wash my hair to see if I can get rid of the smell. It is a viable option to chemical hair colours, but be warned that the odour is very noticible and lasts at least 3 days. You might want to time when you colour your hair so that you will not be in close quarters with others for a few days after. I could give the product 4 stars except for the smell, which reduces it to 3 stars.
