I really enjoyed this purchase , the brush is really natural wild boar (you can compare the quality of the bristles with some cheap brushes from the supermarkets and see the difference yourself). It is very pleasant while brushing and also makes your hair look full and shiny! 5/5 for functioning. In addition, when you are using it on 'not so clean hair', it makes them look more bushy and clean . That is because the brush distributes the scalp oils evenly on your hair.
However, I notices that the brush gets dirty quickly (approx after 2 weeks of usage) and I'm not quite sure how to clean/wash it appropriately so I do not damage it. But i guess I need to do some additional research on that . Don't hesitate buying! You won't regret it :)
