A normal toenail is thin, clear and translucent allowing you to actually see right through the toenail to the pink nail bed underneath. However as soon as the fungal spores get in underneath the toenail the toenail fungus starts to grow within the keratin of the toenail itself. The growing fungus actually causes the layers of keratin to separate.
The separation of layers within the toenail causes the toenail to become thicker but it also changes the way that light refracts through the toenail. This causes a cloudy discoloration that is usually white or yellowish. Those thick, crumbling white and yellow areas of the toenail are the classic signs of a toenail fungus infection.
