In reply to mypyrex:
Mine didn't start to fall out until about the 5th Week. ECX (Epirubicin, cisplatin and capecitabine) was my "cocktail".
Her indoors took great delight in taking the shears to me and giving me a crew cut as I had figured that if it was all going to drop out then the shorter the better. As it happened it didn't all fall out after all!!!
After the last session it took about 2- 3 months before I got to the stage where I had to visit the barber again. It grew back in slightly darker at first but I am back to my pre treatment colour and density.
Stick with it mate. There will be light at the end of the tunnel!!
