From the macrobioitc viewpoint hair thinning
and/or hair loss can be attributed to either too yin or too yang a diet. Usually the yin extreme factor will also be accomapnied by frequent urination and light color. The yang extreme factor by infrequent urination
and darker/stronger color.

In general a diet that avoid the extremes of
yin and yang (like standard macro diet) will
help curb this probalem to a degree, but there are some hereditary issues that may also be going on. For too yang cause you need to back off on salt, baked foods, and use more greens and cooked fruit and salad
(pressed or raw). Also more liquid -- 6 to
8 cups daily. More seaweeds and soy products
will also help.

For more yin cause you need to drink less overall and avoid all fruit juices, concentrated sugars, raw salads, dairy, desserts, oils, OTC drugs, honey, soy milk products, carbonated beverages, iced drinks,
alcohol, black tea and aromatic teas. Umebosi juice or ume concentate watered down
woth stinging nettle tea and massaged into the hair for 1 week will prove beneficial for yin cause.

Please look carefully at your diet and elimination to see if your problem is from yin or yang cause.

I hope this helps.

In peace, Roy
