It's pretty rare to see DNCB still in use for alopecia because of its mutageneic properties.
I would be very careful with topical immunotherapy , it literally burned a hole in my arm with the 2% solution test.
Even at lower doses It was still very painful. It has a reasonably good success rate if you keep up with it and can tolerate it. Unfortunately it did nothing for me. It was very disheartening to commit to it and go through all that pain and discomfort for nothing .
