Hi! I can't answer your question about your neurological condition but I know that for me, those hair loss treatments such as tablets, lotions, shampoo, conditioner and scalp lotion (yep, I used them all for 6 months!!) were all useless and a total waste of money. I thought it was helping initially but I think what was happening was that my hair was snapping off, so it looked like new hairs. I don't know what other people's experices have been but this is just what I experienced.
In the end, I went for scarves to cover my thinning but eventually caved and bought myself some wigs. What you do will depend on what stage you are at in terms of accepting your condition, etc.
Good luck!! x
