Hi there was a very old post here a few days back which caught my attention , it was someone asking if people lost their hair while on opiates. I certainly have lost a LOT of hair during my time of taking methadone. I was wondering how many of you have lost hair or have thining hair while on opiates , and for those of you that did and are now off the opiates, is it growing back.? This has been very upsetting for me losing so much hair , but I was told that hair loss is a side effect of methadone, not sure about other opiates. I am weaning off my methadone, down to 22mgs and I notice my hair is just starting to come back in. Has this happened to any of you?
