Like you I have been diagnosed with LPP. I was diagnosed last December after first seeing my Dr. back in Nov.2015 with loss of hair on my crown. Last Nov. I had a biopsy done and along with the diagnosis was given Dermovate 0.05% scalp lotion to use once a day.It does seem to make my scalp a little sensitive/sore, but whether it can halt my hair loss or at least slow it down who knows. I am due to see a different Dermatologist in May, so am not sure what to expect.
All I can say is that when I was first losing my hair I was devastated and felt very self conscious all the time. Once I was diagnosed with LPP it came as a bit of a shock to know that my hair would not grow back, but also relief to know what I was suffering with and all I can say is that I try and feel more positive these days, although some days are better than others.
I hope my reply may help you to know that there are other people out there who know what you are going through and hope that we can all support each other in times of need.
