Why didn’t I know about these since I was a child? They look like a regular hairbrush but claim to have intelligent bristles. Daisy and I each used one and decided we were never using our old combs and brushes again. Her hair felts when dry and is so hard to unsnarl. Mine stretches and rips when wet. We used this both wet and dry and it just glides through. She even sat and brushed her hair fifteen minutes beyond when it was smooth as silk.
