Q: Can Arimidex result in hair loss?

I have been on Arimidex for almost two years and I am now experiencing hair loss. Is that a side effect of Arimidex?

Yes it is, unfortunately. Since your body is being deprived of so much estrogen by the Arimidex, it affects your hair. Once you stop taking it, hopefully your hair will rebound; though each woman reacts differently, so there's no guarantee. This darned drug has lots of unexpected side effects, doesn't it? At least it's helping prevent the cancer form coming back... Good luck - PJH

SmileThank you so much for your quick reply.  I was afraid of that answer.  I just hope I don't go bald again - but - that should be the least of my worries. Thank you again.

I don't think it'll be that bad... I think your hair just thins, without giving you the "chemo cut" again. Be strong - you're through the hard part. I use "volumizing" shampoo, that seems to help - PJH

I had that problem of thinning hair after taking Arimidex for five years.  My dermatologist suggested Rogaine, but my hairdresser said when you stop using Rogaine, the new hair just falls out again.  So I went with her recommendation to try Nioxin thinning hair system, which I got from my local beauty supplies store.  It is a kit containing three containers: one with the treatment spray, one with shampoo, and one with conditioner.  After 3 months of that I noticed thickened hair, and so did my hairdresser.  I ran out of the treatment spray and am now just continuing on with the shampoo and conditioner, and the extra hair has not fallen out.  So you might want to try it.  I'm happy with the results.

I also had severe hair thinning on Arimidex. The Nioxin regimine, however, did nothing for me but lighten my wallet! I tried Rogaine (minoxydil), and while it is true that you do not want to stop using it, it DRAMATICALLY reversed the hair loss. It works by blocking testosterone at the hair follicles (yes, ladies, we have some - and with Arimidex reducing our estrogen, what little testosterone we have causes hair loss!) Use it night and morning, when you brush your teeth. Like tooth brushing, if you don't brush your teeth they fall out, if you don't use the Rogaine faithfully, the new hair will fall out....Buy 6 bottles at the start, (I get the generic Target or Walmart brand, and 6 bottles costs only $36, so not a lot of $$ invested) and at the end of the 6th bottle you WILL see a significant change. Don't even look for a change until then - takes awhile for the new hair to grow! I have been off the Arimidex for over a year now, and continue to use my Rogaine....maybe some day I will stop - but why? it is not costly ($72 per year), and IT REALLY WORKS!!!!!!! :)

Hello, Helena and others: I too have been trying generic Rogaine (my doc recommended the men's extra strength since I am not having more children). I think it has helped somewhat. Now my question is: How do I get it onto the scalp skin now that my hair is somewhat better? Seems like I usually end up w/ greasy hair and I haven't noticed improvement lately. I do have my hair back after chemo -- that took 6 months but I was glad to get out from under the scarf. So of course I am glad to have hair. I have several years left on Arimidex, and when the light hits my head, well, 80-year-old ladie have thicker heads of hair than me. Reply

Hi Terry - So glad the generic Rogaine seems to be helping. Hopefully, once you stop the Arimidex, your hair will gradually become a bit thicker. I'm sorry I don't have any advice for how to get it into your scalp through your hair - in practical matters like this, I find nurses are often more helpful than doctors. Perhaps you could ask a nurse in your hospital's dermatology department? Good luck - PJH
