Hair Metamorphisis

I was at our Support Group last night and the subject came up. There were pre-op and post-ops there. They asked the female post ops to raise their hands if they had or are having hair loss and about 90% of the women raised their hand.  They then asked the men. None of the men raised their hand.  They said that it has to do with our (female) hormones that we tend to loss our hair..
