Here is something I found in here while reading a good article and I came across hair loss and causes.

As regards hair loss, this is a frequent question. In addition to hypothyroidism, hair loss is one of the prime symptoms of vitamin B6 deficiency, cadmium toxicity, Aspartame poisoning (drinking Diet Coke™?), lysine deficiency, zinc deficiency (white spots on nails?), folic acid deficiency, hyperammonemia (too much ammonia), and fatty acid deficiency. Take your pick :-(. MSM also seems to cause hair loss when there is heavy metals poisoning, particularly mercury.

Pretty good article.

In Sanskrit, tulsi means literally "the incomparable one" and has been revered since ancient times. Tulsi, the holy basil, is said to have grown at the site of Christ’s crucifixion and is associated with St. Basil’s feast.
