minoxidil around 8 months ago, although I don't know if this is totally due to minoxidil use.
However I do seem to get a slightly puffy appearance around the face when using minoxidil.
There is no difference to undereye circles.
It definately causes excess facial hair (very fine downy hairs all over my face and neck) ...I have just had a treatment today (alkalin hair removal) to remove it as it was beginning to annoy me.
The pros...well, it does seem after a long shed, new hairs are appearing and it does not feel so thin as it might have done in previous big sheds. I have been taking supplements etc too, so it might be a combined effort taking place as well.
