I was using a GNC protein whey Isolate it was all I could do to get them down. I switched to the Premier protein from Costco. My surgery was in June 2016- I went thru hair loss and was growing back. I switched the proteins about July of 2017. In November 2017 I noticed about a 1/2 inch bald spot in my head. Fast forward to today’s post and the entire top of my head is bald and the rest is thinning fast and shows no new growth. I have had all the labs done and am good there. Does anyone know if this may have been caused by the protein switch ? I also need to know how much protein one can drink at a time ? Thanx
