Hi Kickle- When can you expect to lose your hair? That all depends on the specific drug that has been prescribed to you. In fact, there are some drugs that will not effect your hair cells. Science has come along way.
My experience had me losing hair during week 7 (after 2 chemo sessions, both 1x every three wks.). I was prescribed a Cisplatin-Docetoxeral combo, a real hair loser!
Also, you may respond differently than the next person would. Remember we are still all unique. I wish you the best. Live fully...
