Back in 2009, I was throwing some major hate at Yes to Carrots for their use of Imidazolidinyl Urea as a preservative. For a year straight, I would send them a stink-o-gram every month asking them to stop using this ingredient. Apparently, I was not the only one. The have really cleaned up their act. Currently, only one product is listed on their website ingredients list contains Urea and I don't believe it is currently in production.
They actually have multiple lines now: Carrots, Tomatoes, Cucumbers, Blueberries. I used up bottles of their Tomatoes shampoo and conditioner I bought on clearance at Walgreens during the winter. My hair loved it and they have a great smell. The only drawback for me is that their products are bit pricey (shampoo $8.99). They are in-line with the pricing for Burt's Bees in drugstores. I will be adding more of their products to my routine as I catch them on sale.
