There are two conditions that I am aware of that are related to candida and may cause hair los. Hypothyroidism frequently accompanies candida overgrowth, and is well known to cause hair loss. Do web search and see if you have any of the symptoms of hypothyroidism. Candida can also cause mineral imbalances. A zinc deficiency is also well known to cause hair loss. White marks on the fingernails are often an indication of a possible zinc deficiency.
