Everything at Lush may not be completely organic or all-natural, but Lush has eliminated the majority of unnecessary chemicals from their products. I love the shampoo bars! They are so fragrant. In a good way! They are round, about the size of a pop can in diameter and about 1/2 an inch thick. You can easily take them on a trip with you (buy the accompanying storage tin, you’ll be happy you did). Lush shampoo bars last forever! I know I have high hopes for someday washing my hair only twice a week, but for now, my husband and I wash our hair everyday and we both use the shampoo bar. It lasts up to 2 1/2 months. For about $10 that amazing considering the high quality of the product and the lack of chemicals. Plus, when you go to Lush, they will likely give you a few samples. Yesterday, I received a sample of face wash and conditioner. Neither of which I have ever tried. I will make sure to let you know what I think!
