She's in her mid forties, is on Tamoxifin and is four years out from her chemotherapy. She says her hair came in full after the chemo, but it seems to be thinning now. Has anyone experienced the same thing and is there anything you've done to curb the progression.

- Of course it can have other causes too. The literature suggests that if it is the cause, then stopping Tamoxifen for a while will probably allow the hair to grow back, and if it does, then other drug options can be considered.

-My onc suggested that once I am done with Tamoxifen (not quite thru menopause yet - they will check again after the Holidays) then he will put me on "Aredia" (I hope I have this one right but I know that if not someone out there will come to my rescue) He said that this particular drug has more of a "androgenic" effect and may help with my thin hair.

-That is a common estrogen-suppressor for the post-menopausal, which would be given in place of Tamoxifen.

Aredia is a bone strengthening bisphosphonate drug to combat osteoporosis, which can also be a side effect of estrogen suppression. He might prescribe that as well if your bone density is low, but not instead.
