Hi Artgirl
Welcome back
...and congratulations on the new additions to your family!

It sounds like you've had a lot of success with this WOE and it really works for you! That great!
I've also recently come back. The first time I went from 230 to 127/135 and I had significant hair loss... maybe I should say extreme. Every morning I'd get into the shower handfuls of hair would come out. Theirs nothing scarier than having that happen and being a woman (not to appear sexist).
I went to a couple of doctors and was told that it was because of the weight loss (not the program) that I was experiencing the hair loss. They did "not" recommend I stop my way of eating! Any significant weight loss 25+ pounds or any type of stress on the body can cause hair loss. They gave it a medical title (I don't remember) and couldn't really help except for giving me a prescription for Rogaine. My pharmacy didn't recommend my using the Rogaine, they said it would compound the problem and make it worse. I really didn't want that! But, my hair was falling out so bad, so I searched for a natural method.
So, I was told to do a few things which really turned the situation around within a month (whew)

. Since then, I've recommended it to a lot of friends. MSM, Biotin, A good hair vitamin and enzymes. MSM helps the hair to grow faster (to replace the loss hair), Biotin helps stop the hair loss. A high grade of enzymes helps to utilize the vitamins from the food that you eat and the vitamins that you take. A lot of people aren't processing the nutrients in their food, so if you try to take supplements they won't help unless you have something to help process the food. Enzymes do that. I don't know of anyone who has followed this format who hasn't had success.
That's what I did, I've had girlfriends starting to bald on top and it's stopped that and now they have full heads of hair. But, it also helps to stop any bleaching process (if bleaching is occurring). Chemicals are really harsh on the hair. So, once your hair is healthy again. In three - 6 months you can start to add it back again.
There may be other successful methods added here. There was a full thread about this on the forum but I'm not sure where it's located now. I know this has worked for about 30 people.
I hope that helps and my best to you!
