I've been using their products for some time but recently tried their Shave Gel (I am British and I can confirm in London we have hard water). I had the same issues with their Shave Gel. I tried using a brush to lather it up, it just turned into a virtually nothing. Then I applied it straight to my face, not much lather but it did feel somewhat silky but not slick enough to give me a good shave. I currently live in Vancouver, Canada where we have soft water, I think it's the same no matter what water you use.
I love the stuff. It's not intended to lather. I wish I could watch you shave with it. It sounds like you didn't wet your face first or didn't use enough of it. I start with a blob about the size of a silver dollar in a wet hand, rub my hands together and apply it all over my head and jaw/neck area and have no trouble shaving. In fact, the hardest thing about it is getting the residual stuff completely off.
I use headslick shave cream and headblade moto s4 for my head, o cremo original, bee bald .this is the king of shave cream! Dollar shave club I don t now! But for the head or face? I love headblade products! I use headblade 10 years! By friend
