I think everyone has good points here...but for me the simple fact is this. Indian girls (for the most part) that have the floor length hair...are fairly religious and just wont do what is asked by the hair community. And I dont just mean hair porn. In general if we want to get the same long haired girls just brushing oiling and flipping hair around in a non HD product...there are far to many producers out there already doing that.
The missing link is meeting the girls and understanding their beliefs and working with them. Its swimming against the current for sure. But bottom line is there is money to be made by the girls, the producers etc if they can find this missing link.
There is the same problem in hair cutting videos. There is only so many long to bob cuts you can see cut the same way in the same fashion from the same angles. Its OLD already. No one is doing it different and not for lack of trying...its the models who say no or lack of talent of the stylist.
The whole community needs someone to come on the scene and blow our minds!!
just my 2 cents
