Tamoxifen - hair thinning / loss

Hi all

My partner has successfully been treated for BC, where she has had a mastectomy and a round of radiotherapy. Thankfully everything has seemed to have gone to plan and she is now talking tamoxifen, and has been for approx 6/7 months. Side effects have been very minimal however in recent weeks, she has really noticed that her hair is beginning to fall and notices a lot when brushing her hair, running her hands through her hair which is now causing her a lot of distress. She has quite thick hair and she is terrified of losing her hair.

I'm wondering if anyone has experienced anything similar whilst taking tamoxifen? Did anyone lose all their hair? Has anyone had any luck using any products to reduce the effects?

My partner has been so strong throughout the process and I know we have been so fortunate not to experience any real significant side effects thus far, this has really knocked her confidence.

Any help / suggestions would be greatly appreciated
