HELP - Atkins & Hair Loss

Hey everyone
A month ago, I told you guys how scared I was about starting to lose my hair on
Atkins, and that I was going off of it, and onto low-calorie. I started
low-calorie - and my hair replenished, but I didn't lose any weight - just
maintained. I got back to college, and my friend Beth, who I hadn't seen in 4
months, came up to me GUSHING about how great I looked & how much weight I
lost. Two other friends said the same thing in the next days later. :]

I figured I couldn't just give up on Atkins, on my goal... so I went back on.
I'm taking a One-A-Day Carb Smart multivitamin, and am on Induction (for best
results). I get no Essential Fatty Acids b/c I don't eat fish & aren't taking
Omega-3.

I've noticed my hair is getting thinner again - from the thickness it used to
be. I want to stop this, if not reverse it, and don't know how.

Somebody recommended taking a 1000 mg (or was it mcg?) pill of Biotin every
day, in addition to my multivitamin, which already contains 450 mcg of Biotin.
Would this be too much Biotin in addition to my multivitamin? Does anyone know
a successful and healthy (not ODing with too many supplements) cure for this
hair loss?

I want to lose weight, but not the hair.

Please help me!!!
