I found this new article from India Times that says dandruff is a hair loss cause. You said it wasn’t.
This reads like a brief article with bits of truth and bits of confusion all mixed together. I would doubt that this was written as a means to educate by someone who is an expert. The term trichoanalysis (or as the article calls it, Tricho Analysis) indicates the analyzing of hair (tricho) which is really not informative on any level. Look at one of my recent posts on dandruff for the real scoop — What is Dandruff and Why Do I Have More of It Than My Friends?
