Hi there,capati92! Nice to see this flow of interesting conversation going on. Hmm....a presumed thyroid problem you say? I suggest you go check that out immediately. In several cases, medical conditions such as either hypothyroidism or hyperthyroidism could have occurred for a very long time but we won't really be aware of it until much,much later when it's way too late or something. That's what I learned anyway. Do you notice any drastic change in appetite, dramatic gain or loss in weight, lumps on your neck,etc.,etc.? Actually um, even if you don't have the last bit, you should always go for early screenings and blood tests just to pinpoint the cause of your hair loss. If it's indeed a thyroid disorder you're having, you'll still probably be in the green zone....perhaps yellow zone. I have no clue as to your thyroid status now but at least you know, as they say, detect it all early so you can eradicate it faster (IF you have the condition for sure, I emphasise once again).
Oh and about Minoxidil (yeah,your post really fascinates me A LOT. I'm a 1st-year med student,you see, so these issues get me really inquisitive and investigative and drive me to satisfy my thirst for learning), well I actually asked around in other boards regarding its metabolism and excretion. Apparently,it takes an average of about 4 days for it to be excreted from the body,according to research data provided by some very kind,very helpful users.

Just scroll down for the feedback,will you, capati92? Hope that's the info you've been looking for. Not sure if it was safe of you to donate your blood just after a mere 2 days of last applying Minoxidil topical.
I wish you all the best, capati92 and hope you will always remain in good health. xoxoxoxoxoxoxoxo
As per the list supplied by Mayoclinic (http://www.mayoclinic.org/mcitems/mc1400-mc1499/mc1402-50.pdf), none of the drugs you are taking or applying on the scalp can cause any problems while donating blood or to the recipient of the blood you donate. However, please do mention it at the camp before you donate blood. Take care!
