You won't go bald, if that's the worry, it seems it is a common side effect of ketosis...or so I was told...although I seemed to be the only one affected in my group (lighterlife) with lots of falling hair...it soon grew back once on normal food and I had loads of baby hairs growing for ages, so it came back...thing is it is wavy rather than straight now, but I think that had to do with pregnancy and birth rather than the diet...or maybe it was a combo?
