Is there anyway to avoid weight gain and hair loss while on tamoxifen ?

Hair loss tamoxifen: Tamoxifen related hair loss is androgenetic due to blockade of the female hormones. One of the first steps we have to treat female (or male) pattern hair loss is topical minoxidil. It does not involve any hormones and therefore should not interfere with your treatment of breast cancer. Also, thyroid problems can contribute to hair loss, as can iron deficiency. I suggest having both checked.
