Caprylic Acid is an anti-yeast supplement available at any health food store which should be used internally, and is used in lots of good cosmetics, so consider applying it externally. And try hot oil treatments or hair dressing with Cocoanut Oil, which contains Caprylic Acid. This could be why the "secret of cocoanut oil" led to luxurious hair growth in cocoanut cutters--they were killing Candida!
Avoid any raw egg whites, which blocks Biotin, and can cause thin hair. Biotin is a great supplement to beef up hair and nails AND it inhibits Candida replication! Do this daily!
