Ive very thick hair, just below shoulder length. When I was on LT two years ago, I did notice my hair thinning a bit, then I had a bit of a knock (I fainted and spilt my head open) came off LT and started refeeding and that's when I noticed the lumps of hair coming out. I was distressed but within a few weeks I could feel the hair growing back. It happens to some people, and it can be destressing, but others dont notice it. Fingers crossed you will be sorted xx
