@Kiahdee I too am on kisqali and letrozole, have had hair thinning, which only just started so like @Ali55 cut my hair short, actualy super short lol, lost my eyebrowswhich doesn't bother me as I wear glasses so not so noticeable, been getting occasional nausea about half hour after taking tablets, dry skin, shocking nails but it's doing what it is suppose too by keeping my cancer in my bones under control, I work part time, yes get tired but just go to bed early lol, I've been taking it now for 8 months, if it keeps me alive then hey ill take it I can deal with the side effects. Hope all goes well for you 😀😀😀
