I had the same chemo as you, and also Herceptin. My last docetaxel was in March this year and my last Herceptin will be February next year.
I've read that docetaxel(=Taxotare) can be really rough on hair follicles and some people (only a small percentage) have permanent hair loss. On the other docetaxel is a stronger ant-cancer drug than FEC and a higher percentage of tumours respond to it.
My eyelashes and eyebrows grew back very quickly and are as thick as ever.
I got some thin white fuzz on my head fairly within about 4-6 weeks, but it gradually thickened up, so now I hae a full covering of hair, but it is still very short. Not much more than 1cm at after nearly 4 months. But I am so happy to have hair, I don't mind the buzzcut. Hopefully it will eventually get longer.
If anyone is interested, I am recording my hairgrowth (with photos) on my blog - how vain is that!. Also my hair colouring "experiments" - I didn't like the "chemo white" hair colour.

But I still have no hair on my forearms and hardly any armpit hair.
