HMTC (Dublin) on 08/08/2021:

I was diagnosed with Frontal Fibrosing Alopecia supposed to be related to Lichen Planus. I have found B6 cream to be very effective in treating this. Reconval is a B6 cream, though not always available. Liquid B6 (particularly Pyridoxal Phosphate) is just as effective.

Note: B6 may trigger cold sores, which can be contained with Lavender cream.
