I did LL and lost 7 stones, around week 6 I started to shed hair noticeably on my brush and in the bath. I lost a reasonable amount over the course of a week or two and then it stopped. I have a lot of hair and you could not tell i'd lost it, I've been on CD on and off ever since and haven't had any hair loss, so I think it's just one of those things. For me I made a choice to possibly have thinner hair for a short period of time (very short as the hair folicle grows hair back again) rather than be 10 stones overweight. I do think I was the only one in our group though that suffered from it, so it's pot luck I think - Joe
