1) Probiotic for Dandruff Home Remedy
When the scalp becomes infected with yeast organisms, dandruff is often the result.  This is the reason anti-fungal shampoos like Nizoral are used for this.  When dandruff won’t go away, it is commonly an indication of yeast overgrowth in other parts of the body and usually in the digestive tract.  The root of the problem is the digestive tract and diet is the main culprit.  Stay away from foods that promote growth of yeast.  These would include vinegar, alcohol, peanuts, sugar, mushrooms, dried fruit and refined carbohydrates like white flour pasta, bread, white rice and especially sugar.  For several months stick to fish, fresh veggies, lentils, whole grains and beans.  Take a probiotic supplement which increases the good bacteria in the gut thus crowding out the overgrowth of yeast.   Take the probiotic for several months.

2) Dandruff and Traditional Chinese Medicine
According to Chinese medicine, the most prevalent cause of dandruff is "liver blood deficiency."  One of the things that blood accomplishes in the body is to moisten the body.  So to be "blood deficient" does not mean there is a lack of blood in this case.  In acupuncture there are six meridian points on the back which are called the Magnificent Six.  When these are stimulated by acupuncture or moxibustion, they will nourish the blood.  There is also a point close to the knee called the "Sea of Blood" point and this also helps with dandruff.  Another cause of dandruff defined in Chinese medicine is excessive "heat" which causes red itchy places on the scalp and other locations.  For this, a point by the elbow is used to clear the heat.  Yet another scenario is that the dandruff results from too much "damp."  This is when bodily fluids become stagnant and this causes greasy hair.  There are specific points to correct this.  A common Chinese herbal home remedy used for dandruff is a mixture of peony (bai shao) and angelica (dang gui).  These both nourish the blood will help with dandruff. This is an excellent home remedy for dandruff.

3) Ground Flax Seed
My dandruff home remedy is to take a couple of tablespoons of ground flax seed every day.  I add to my hot morning cereal, salads and vegetable dishes.  Sometimes I just eat it straight and wash it down.  The flax seeds must be ground.  They are high in omega-3 oil and I think this is what does the trick.
