If you are on Nutrisystem and notice you are losing hair, I believe it is due to the diet.  My story:  I did this diet two years ago and lost 20 lbs.  I liked the food and it was easy to follow. I then started losing my hair. I went to a dermatologist and they gave me Spironolactone to regrow my hair. It worked!!  I heard this diet can make you lose hair but didn't think that was my case. I started Nutrisystem again two months ago. I have lost all the new hair growth and am back where I started. I called to cancel my subscription and when I mentioned why I was canceling, the rep hung up on me ( after holding on for 20 minutes). I had to call back. I got it canceled  and asked for a supervisor. Surprisingly, they were all in a meeting. How convenient. I left a message but I'm sure they won't call me back.   So angry and disappointed....
