Hi, I have some questions regarding minoxidil. should i start off with the 2 percent or 5 percent? I have started using the 5 percent and read somewhere that i should start with the 2 percent and save the 5 percent for later down the road......is it necessary for me to change to the 2 percent? and i feel that after applying minoxidil....my hair look even worse right after application.....scalp is clearly visible......does anyone have the same problem? and i've been applying it to my whole head once a day at night.....and it usually takes me 2 doses to get enough application around my whole scalp....am i using to much?
