A couple of weeks after my friend finished her radiation, she cut off the last few strands of her hair. We noticed, her hair had fallen less drastically than most others. Basically, the rate of her hair fall was way slower than the usual that we’ve seen. With my own mother, her hair fell within the first three weeks of Chemo. Wondering how that happened, we realised that it was the temperature Archana was used to. She always sat in an air conditioned room, even in her house, the AC was always switched on, keeping her head cool.
The cold air over the head usually narrows the blood vessels. Cold packs on the head generally avoid quick hair fall. Cold caps and scalp cooling systems work by narrowing the blood vessels beneath the skin of the scalp, reducing the amount of chemotherapy medicine that reaches the hair follicles. With less chemotherapy medicine in the follicles, the hair may be less likely to fall out. Idea is to just keep the head cool. But nevertheless - check on this with your doctor and see what they have to say. A doctor I had spoken with did mention that you don't necessarily have to wear cold caps, you could substitute it with just cool towels or an ice pack wrapper up in cloth as well.
We would love to hear about your experience in dealing with hairloss during Chemotherapy.
