Hi @rose,
Believe it or not this is probably the only side effect I haven't had on that drug...uggh. Try the viviscal hair thickening shampoo and conditioner, I used this all through chemo with the cold cap and it works quite well and smells lovely. You can get it from Priceline.
There is also a product called Fusion hair tonic that seems to get good reviews. It is a tablet that can be purchased from most health food stores. It is a bit dear, about $40 a bottle. It was recommended to me by a friend who is a hairdresser wtith a number of clients using it post chemo with good results.
I did ask if I could take it throughout chemo but they said no. Not sure about taking it with Tamoxifen, you might need to email the company and ask.
xoxo
