I took Prolia every six months for 2 years and yes my hair broke off and fell out. Then my Dr. wanted me to do Reclast-NEVER NEVER AGAIN. I had the infusion last January and I had every side effect listed. By September I was noticing the side effects were diminishing but my hair is terrible! I don't know what I will do from here on-I am 75 yrs. old and I am starting to think I should take my chances???
