I just recently began with the hot flashes and night sweats. Not unbearable, but annoying. I had just been to have my hair done and a day or two later realized that I had a lot of damage, short breakage, etc. I thought my hairdresser had done something wrong. When I discussed this with her, she said that the hot flashes, etc. may be the cause of breakage and hair loss. Is this true? Am I doomed to thinning hair for the rest of my life? I am only 51. She also suggested thyroid problems since my sister had thyroid cancer and had her thyroid removed. How long with the hot flashes and night sweats last? Will my hair revive itself again?
