Tamoxifen and hair issues

Hi All

Is anyone having issues with their hair whilst taking Tamoxifen?  I started taking it February 2021 and since then well to put it bluntly my hair has looked sh*t!  I know lots of people have issues with hair thinning (I am noticing more hair on my hairbrush).  Under normal circumstance I have a lovely shiny chin length bob cut, but recently my hair looks like its been snapped off halfway down and sticks out everywhere.  I have tried hair masks and am seriously considering asking my hairdresser to recommend something (no doubt stupidly expensive).

Do you have any tips?

Many thanks

Hi Shona,

Sorry to hear about your hair. I just wanted to let you know I was on Tamoxifen for just over 3yrs, I’ve now been off it for a year and a bit. Basically after chemo my hair was growing back thick and curly. Then I went on Tamoxifen and my hair gradually started thinning. Mostly at the crown and hairline. My eyebrows are still thin, patchy growth of hair on body. I’ve been holding out on hope and just taking Biotin and using various shampoos that claim to help strengthen hair. Nothing has worked so far, with time it seems to be getting a bit better but still not what it was. Doctor said tamoxifen stays in the body for a longgggg time and my hair has been impacted a lot, for whatever reason, all the drugs…it’s like the drugs are in my hair follicles! I may decide to go and see a Dermatologist. Any way, will keep you posted if I find anything more that happens!

Hi ladies,

I have been on tamoxifen for nearly 6 months and I seem to be losing a lot more hair than usual and feel that my head of hair has thinned. I am having a check up soon so will mention this & see if there is anything I can do. I would feel better to know if the hair will regrow once the tamoxifen has stopped even if that is 4.5 years away.


I’ve been on tamoxifen since 2020, 2 more years to go. My full head of soft hair has gotten significantly curlier and more coarse. It also breaks as fast as it grows.  I’ve been researching side effects because of all my joint pain that just won’t stop. 
anyway, was told tamoxifen doesn’t do anything to your hair. Glad to know I’m not alone.

I’ve used Vegamor serums off and on and find them helpful for thickening the hair around my temples.
