Hair loss due to Anastrozole

I have been on Anastrozole for the past 10 months and experiencing severe hair loss and thinning. Any suggestions what I can to to prevent this. Thanks

I've been on Anestrozole for 5 years this December. Luckily, I'm finished with it then. Yes, I have experienced hair loss and thinning too. I'm also on Prednisone (not for the cancer) and thought that also promotes hair loss. I've been using biotin and collagen shampoo which supposedly "helps to create the appearance of full, voluminous, healthy looking hair".. I keep my hair fairly short, about 5", instead of the longer length which seems to show the scalp more. I have yet to find something that really works. Good luck.

I just finished 5 years of Anastrazole. I had hair thinning more than I ever noticed before treatment. I was advised not to wash my hair more than twice a week, not to use a hot setting on the hairdryer, and to use a wet dry brush to brush my hair gently. My beautician told me I did not have any “bald” spots. I was also told supplements were useless considering it’s a side effect of medication for cancer. That being said, if you try them and you think they work. Great. Best to you.

I have had hair thinning. Been on a anastrozole almost 2 years. I shampoo and conditioner with free sulfate and use cool setting on my hair dryer and I use a pix on my hair and cool setting on my hair dryer and use a curling iron everyday. I try not use hairspray too much. Weekends I let it air dry.
It seems to be growing a little.
I also take my multivitamins and vitamin d every day. Don’t know if that helps.

@indygirl2 Hello. Have you noticed it coming back since you finished Anastrazole?

As I'd been on Anastrozole (14 months) and am currently on Letrozole (28 months) since losing all my hair to chemo, I find it difficult to know what to attribute my thinner hair - drugs or age (I'm 69). I used to have rather thick hair; currently it's a bit on the thin side. As it was growing back from chemo (total hair loss) my hairdresser recommended Nioxin shampoo and Nioxin Scalp Therapy (applied to and meant to moisturize the scalp). I think the goal is to brush your hair a lot to stimulate the scalp and hair follicles and improve blood circulation. Scalp massage is also valuable. The shampoo I believe is also meant to be a clarifying shampoo to rid the scalp of old skin cells. My take is clarify, moisturize and stimulate by whatever means works best for you. I buy my Nioxin at my hairdresser, but I've also seen it at Ulta and on Amazon. I hope you find something that helps.

Just a thought. Talk to your oncologist about taking Anastrazole every other day instead of every day. There are studies of all three AI's showing that half dosages are just as effective. Perhaps this might mitigate the hair loss a bit.

I’ve only been off the Anastrazole one week. Oncologist told me anywhere from 2-8 weeks for side effects that are going to go away should be gone. Any side effects after the 8 weeks he told me they might be permanent or could just need another 4 weeks. Usually after 12 weeks if they are hanging around and are bothersome , I need to check with my GP. He did say hair growth may take around the 4 week mark to see results.

What brand multivitamin do you take?

Good question. I've been on anastrozole for two years with no effect on my hair. Hair loss can be caused by many things, including stress.
