tired of the thin hair

[karla]

I have had thin/thinning hair for as long as I can remember. Everyone comments that I have no hair. For the last few weeks my spouse has made comments about the hair loss. Some think that my thinning hair is from my having gastric bypass surgery 5 yrs ago, and yes my hair did get thinner with that, but I have always been very thin. My hair seems brittle and dry yet oily.
I catch all the hair loss jokes around and until now I have not let it bother me. But lately my hair loss has worsened. HELP!
