This blend consists of orange, lemon & grapefruit essential oils. Depending on frequency of use, this bar can last 1-3 months or longer. I have long hair that goes to the middle of my back. With daily use, one bar lasts me about a month. To get the longest life out of the shampoo bar, allow the bar to dry between uses. If it sets in water, it will get soft on the bottom & produce smooshy goo. Doing this on occasion (absent mindedness happens, yo) won’t ruin the shampoo bar. It’s not that fragile. :) Ingredients: sodium cocoyl isethionate - this is a sodium derived from coconut oil. It’s ethically & responsibly sourced. This is the stuff that makes the bubblezzz BTMS50 - this is the good stuff. It’s a vegan emulsifying conditioner. Amazing stuff! cetyl alcohol - this sounds scary.
