There are two key factors to decide the quotation:

One is the cost of raw hair which is extremely different with different types( cuticle remy, remy, non remy etc) . for example, the cuticle remy hair is around 40%-50% higher than the non remy hair( Dead hair that is falling naturally).

The other factor is the hair length ratio( double drawn, single drawn, 30% ,40% single drawn, etc). The more the long hair is, the higher the price would be. For example, the double drawn is around 30%-40% higher than the single drawn.
