I thought it had but since I had my first trim about 6 weeks ago it has thickened up and other than some curls on top is returning more to the hair I had before! I had thick, strong but straight hair before. My hairdresser tells me she thinks it is heading that way again (just had a second trim and it is almost into the style I want to keep!) For me I think it has been the chemo rather than the tamoxifen that has had the biggest effect on my head hair. Mine has been very slow growing compared to some other ladies on here. Like everything, we all have different effects and even then these effects change as your body adjusts.
Enjoy those lovely flowers and remember we might have been unlucky to get breast cancer but we are VERY LUCKY to have such wonderful men in our lives. :) xx
