The hair loss and acne are common symptoms to any candida infestation, and the diet can quite possibly “cure” these ailments; the only problem is that it takes time. If you noticed a significant change for the better after the 2 weeks, consider going on the diet for a longer period of time. For me it took 4 months for the hair to grow back while on the diet strictly; since it seems that you are healing fast, it could grow back much sooner than this time period.
Are you eating any dairy including butter? Caffeine/coffee?
The quinoa is a tricky one and I’ve noticed that many people have problems with it, while others do not. You may want to consider saving it for phase 2 if possible; it is considered a grain. Buckwheat could be a good alternative as well. Did you notice the acne around the time you started to eat quinoa?
Also, if you can do some kind of sweating treatment semi-regularly such as a sauna, hot tub, steam room, or even a hot bath…this can clear out the toxins in your body much faster. This could also potentially clear up your acne problems. One of the ways the body detoxes is through the skin; while on the candida diet your body/organs are fairly overloaded dealing with the toxins, so a common way to get rid of toxins is via the skin.
