I lost my eyelashes a week after finishing 6 months of chemo. My hair had started growing back on Taxol. One of the nurses told me that eyelashes have a different cycle to the rest of your hair so they are lost at a different rate and that they were already growing back. This made me feel better. At the time it was the most distressing parts of chemo for some reason.
2 years after finishing chemo my hair is starting to straighten out. Although it's still very grey. My nephew had a brain tumour a year ago and his hair has grown back darker, but still very straight. He's doing well now.
