Home Cancer Expert Q&A Hub Coping With Treatments & Side Effects


I've been on Letrozole for two years after lumpectomy and radiotherapy.

I'm noticing that my hair is becoming very thin and I can sense a smell from it even when newly washed. I have tried numerous different shampoos but nothing seems to make any difference. I'm unsure if the tablets are affecting my sense of smell or if there even is a smell !!. Has anyone experienced the same thing?

    Hello, welcome to the community,

    Until you had raised the question I hadn't given any thought to the medication possibly affecting the quality of hair!

    I haven't noticed any smell. I was on Letrozole and have changed medications, but I understand that the breast cancer meds can possibly cause hair thinning due to the oestrogen-lowering effect of them (like Tamoxifen. Letrozole, Exemestane etc). My hair is quite thin on top, but I put that down to the effect of chemo, and how my hair re-grew. But perhaps it is the meds as well.

    It will be interesting to see if anyone else has had this experience you have had. There are many here with a breast cancer diagnosis, so I doubt you will be the only one!

    Best wishes,

    Lou x
