Denman Devotee or Denman Detracter?

I like many naturals have a Denman brush, I also have a shower brush. I recently saw a vlog where someone was experiencing significant hair loss from using the Denman brush. After some thought, I realized I had heard and read similar stories on hair boards and forums. I use my Denman after detangling in the shower with my shower brush so I haven' t had any problems. In the interest of fairness though, all hair is different and I wanted to let new ( and experienced) naturals know that the Denman brush is not a one-size-fits-all miracle tool.

Please voice your opinion. :)
