even loreal said that minoxidil does the same thing as aminexil, but aminexil does it better. they are in the same family of chemicals. that break even point sounds appealing. I heard some good things about spectral DNC. maybe i'll give it a few months some time. $35 plus shipping. I don't know. i was not really planning on trying retin-a just yet anyway. and no one will tell me how the copper peptide content in it compares to folligen or tricomin.
