Any suggestions how to permont hair regrowth sooner?All iron levels were good.Is it a fact a true hormone panel cannot be done because I take a very low dose birth control pill?All that has bee tested is testosterone very low.012 and dhea sulfate 30.Should I take some hormone replacment for these two once my hair situation in straighten out?I am 46 and feel like my emotions,sincee of well being are on a roller coaster.PLEASE give me advice.
