Tamoxifen and Hair Loss in Women

Hello Doctor,
I have been taking Tamoxifen for 2 years after Breast Cancer treatment in 2003. I have noticed that my hair is thinner lately and am wondering if the drug is the cause? Any suggestions? Thanks!

When hair is lost secondary to a drug like Tamoxifen, it is not unusual for it to come back with a different texture. You may not know the entire story until you undergo an entire hair cycle (2-6 years) or have the drug impact completely gone (2-6 months after stopping the Tamoxifen). No real suggestions, other than to get a good baseline on miniaturization and the distribution of miniaturized hair to, at the least, command the diagnosis of female genetic hair loss (just in case you are in that category of women with thinning hair).
