Eyebrow Loss with Docetaxel

I finished chemo in June this year and despite having now got a full head of hair, some eyelashes and hair other places too(!), the old eyebrows are still completely non existent!  I had the same treatment this time as 9 years ago but my eye brows returned last time.  It is only a small price to pay to keep the cancer at bay but on a day to day basis, it is a bit of a pain to have to draw my brows in and sometimes, I forget!  One time when I was still wearing my wig, I drew my eyebrows on with the curtains drawn as I had not put on my wig and later discovered that I had been walking around some shops with fluorescent orange eyebrows as I had used the wrong pencil!  Before I bite the bullet and get expensive tattooed brows, what are other people's experiences of getting their brows back after Docetaxel - how long did it take?
