Love this product, I really enjoy the smell of this shampoo.
However, I would recommend using it in conjunction with a silver shampoo, alternating between both. As this product, unfortunately, isn’t a silver shampoo which is needed to stop the yellowing effect. I did find that alternating the two helped with preventing the yellow effect as well as preventing the purple tinge from too much silver shampoo.
Overall, I would definitely use this again. Don’t forget to use it with the conditioner for even more added benefits.
