LCing does not cause this, angdan. Any diet, and more specifically, any rapid weight loss or sudden stress can cause this to happen. The effect (hair falling out) usually happens 3 to 4 months after the traumatic event (rapid weight loss). It's quite common and quite temporary.

There is a great thread with some good external links that explain just what is going on and how to best supplement your diet to help speed the regrowth.
