My eyebrows started falling out rapidly for no reason last October. As well as PRP I am considering LDN as there are suggestions it can help some kinds of alopecia. I have also found anecdotal patient reports of hair LOSS after starting LDN. How high a risk is it Ldn could make my situation worse. I want to try it for other health reasons too but not at this cost! ADerm suggested the loss was SD related but another that it was likely TE from stress / tea tree.
