Hair Loss Remedies for Thinning Hair on aromatase inhibitors?

I have been on Anastrozole and am now on Exemestane. I have not noticed any thinning of my hair.

I am taking letrozole and definitely noticed thinning, not as bad as hairloss from chemotherapy, but emotionally devastating to lose so much hair after it had grown back. My oncologist recommended Viviscal and warned me it world be at least three months before I'd notice a difference. She was right on both counts! By the third month I "thought" it was better. By the fourth month I "knew" it was. I continue to take one pill with breakfast and one with dinner and my hair is back to the quantity I had before cancer treatments.

I started with Anastrozole in May 2024 - I hated it! I couldn’t even walk. I was switched to Letrozole. My first month I had Letrozole by Accord, was much more lenient on joint pain, I didn’t notice hair loss. I now take Letrozole by Aurobindo which so far barely any joint pain. Once in a while a few weird tingles. I do walk every other day for about 25 minutes too.

I've been on letrozole & ibrance for 8 months now. Just in the past 2 weeks my curly hair suddenly went straight and my comb has more hair in it then I like. Seems strange to me. BUT my MBC in my sternum, liver and some lymph nodes has significantly shrunk as per PET scan, so I'm very thankful for that.

Can you please share where you found the studies saying taking Anastrozole every other day is just as effective as taking every day?

Can you please provide the link to the full study? I'd like to read the whole thing please. Thanks so much.

The link is at the top of my post.

The link I've provided shows the same efficacy at lower doses including half the standard dose. Therefore my oncologist gave me the option of taking a full dose every other day or taking a half dose (half tablet) everyday.

The half life is 50 hours so it wouldn't appear that there should be much if any significant drop-off in the level of the drug present in the body. In fact, because I was not tolerating the drug well, my oncologist suggested that I take the drug for 6 months and then take a month off. I no longer have the link, but I also ran across a study concluding that 9 months on and 3 months off had
the same or similar outcome as taking it continuously.

I am taking both letrozole and Kisqali for MBC that I started in February 2024. I noticed my hair starting to thin a few months later. I started taking Nature's Bounty Womens Multi Vitamins w/50 mg Collagen, Vital Proteins Collegen Peptides, and also starting washing my hair with Kitsch brand Rice Water protein shampoo and conditioner. When I got my hair cut in August even my hairstylist commented on how much thicker my hair was getting and I have noticed a big difference. I am still losing alot of hair when I brush and wash but it isn't nearly as thin as it was before starting this regimen.
