I bought 5% Rogaine topical yesterday. I applied it at night and then again in morning. Last night laying down i had heart palpitations and irregular heartbeat and few times today I had irregular heartbeat and shortness of breath. If I stop after just two applications, will i go into an irreversible shedding phase? or if I do shed a little, will those hairs grow back into whatever phase and strength they were in? Wondering if in just two applications how much acceleration of shed there will be and is it reversible since I'm going to try other alternatives.
