It isn't that interesting, same as you said earlier, there is no scientific evidence to back up your claim. I have always used styling products in my hair since the age of 13 or 14. My hair loss started around 19, same age as my father before me (very much doubt he used styling products) Anyway, started propecia, end of hairloss, end of story....Still use styling products! Don't go scaring people off from using them. Used correctly they help your hair look good possibly even help make your hair look thicker. Many of the young guys coming on here, who have just started balding, have a very real possibility of halting and even reversing their hair loss using the PROVEN treatments. Threads like this just confuse people and cause people to waste valuable time in treating their condition. I have yet to see any success story stating that quitting the use of hair wax and the application of Turmeric to the scalp has reversed their hair loss.
