They go a customer for life, a hidden gem for excellent oral care because I have noticed my teeth getting whiter and the oil pulling stuff from beneath my gums.
Tough it is a quality product, I hate it. It may easily stain your shirt, not something you have time to on a busy morning. So you have to deeply bend toward the sink. Anyway, you must carefully wash the sink and toothbrush after finishing, because it leaves black stains. And you also have to wash your mouth, so to avoid occasional staining, and that's bad, because it is better not to wash your mouth after brushing. I have no force for this, and surely won't buy it again. What irritates me is that Hello stopped producing their parallel product, that is, the same toothpaste, with fluoride, but white, without carbon. May be they think they can force us, clients, to buy the new product, but they are DEEPLY wrong. These days you do not force clients!
