Why we love it: Ever heard of it? No, this isn’t a hand sanitizer – but it does keep things clean! This water soluble preservative helps us keep our products in tip top shape for you. By preventing microbial damage (bacteria or fungus) we can rest easy that our simple but effective products remain pure. We include it in our shampoo bar, our leave-in conditioner and our wash-out conditioning balm. This viscous clear ingredient has no scent and is undetectable to the eye but manages to protect our haircare formulations with ease. With this preservative, we get the best of both worlds by being able to use great ingredients, with a much longer shelf life.
