Is your Hair Thinning with AIs?

I have been on Kisqali and letrozole for 8 months now and my hair is still the same as before, it's just the luck of the draw as to what side effects we will get.

I haven't had a change but do know some women can suffer male bald pattern thiness after menopause so it wouldn't be surprising if it did thin. Also too as @Afraser said...our hair loss cycle is very different as for most of us it grew into together so very possible we could shed a lot together but these do  grow back..

High cortisol levels can also cause hair to thin. High crtisol levels happen with stress and with some other health conditions.

Hi all
ive been on Letrozole and Kisqali for 18 months and I’m now wearing a wig. My once thick hair has thinned out considerably with a small bald patch on my crown. In the scheme of things staying well and is so, so much more vital and a small price to pay. However losing my hair continues to be challenging.

My hair certainly thinned out on Letrozole. I was on this for 6 years, before swapping back to Tamoxifen. My hair is still very thin, so think it might be like this forever now.

Three months on Letrozole and so far no difference with my hair. It seems to have grown back as thick as it was before.

Too early for me to know (ha ha) but I did notice that the texture of my hair became different during menopause. Mine's always been very fine but a lot of it. It seemed to be lankier and finer.

I hit a patch (no pun intended!) about 2 years in - just suddenly found more hairs on my brush than ever before. No bare patches, and looked much as normal (my hair was very thick and quite coarse) but more hairs - not handfuls, but after losing your hair, you can be easily alarmed. The upshot after a round of oncologist, GP, dermatologist etc etc was that I may (who knows) have encountered an alteration in my hair's normal shedding pattern. Which can happen, and it's not always clear why. The norm had apparently been remarkably low, or at least visibly so. I tested clear for vitamin deficiencies, alopecia, had a bit of dandruff. The new norm is that I shed a bit more, but well within acceptable levels, and yes, I think my hair post chemo is finer than it used to be. 

Everything has been fine since. I do take (on the dermatologist's advice) biotin. No idea if it helps or not.  I think it takes a long time to get hair over chemo - we all focus on the regrowing, for good reasons, but the settling in (colour, texture, shedding patterns etc) may take quite a long time. 

I thought it might be femara, shifted to another AI for 3 months, but no difference. My oncologist said there wouldn't be! 

Yes arpie I have also noticed  my hair thinning,especially since  I started  on Aromsin ,good thing I had plenty of hair to begin with.
