Anastrozole hair thinning

Oh I understand what you mean.  Have the same problem.  I am very careful with the products I use and don’t tie my hair back in any tight hairstyles.  If I dry my hair I use a cool setting and dont dry it for long. 
The hair loss is due to the loss of estrogen and also can be from androgenetic alopecia.  
I have been in anastrazole for over 3 years and feel like I am maintaining my hair.  I did buy an Irestore helmet for myself as a Christmas present after I had been on anastrazole for 6 months.  It was expensive but I got it on sale and it has helped.  They have one out now that is more elaborate with more red lights but  so much more expensive so no way.  I don’t take any supplement for my hair as waste of money as I am not deficient.

 Hope our hair get thicker when we stop drug.  
Take care.
