Hair help: Many factors can cause hair loss or thinning, eg, hormonal, medical, medications, nutrition. See your pcp or dermatologist for exam and guidance. Also don't use hair products or remedies without professional advice. See: http://www.mayoclinic.org/diseases-conditions/hair-loss/basics/causes/con-20027666 I hope this helps. Best wishes.
