The worst brush ever, even if everyone uses it and says it’s great, well, it’s really not. This brush has a razor, so blades that cut everything. A brush shouldn’t just remove whatever it wants, but if it has blades, it’s like taking clippers without a guard and cutting your hair—you lose everything, not just the ends. And it’s the same with this brush: as soon as there’s a blade, it doesn’t make a difference and cuts all the hair.
