Sounds like he has some sort of psychological problem . Maybe he needs therapy ? <| sep |> You say dangerous . Dangerous like adverse effects such as beard fall or is it just skin burning , irritation ? I did apply rosemary directly and I had a burning skin for a while . After a 2 hours my skin felt normal and the burning sensation was getting reduced gradually until those 2 hours . I did that for a couple of weeks and I saw massive gains in the beard hair ! And it completely changed my beard texture to a new better one . Most of all nothing happened to my skin . No pain no gain . So it really the burning skin and irritation or is it dangerous beyond that ? People never actually tell why it ' s dangerous clearly .
