Wholesale hair-extension pricing is determined by the product specification, not only by length. The main variables include starting hair, processing route, usable length, net hair weight, end fullness, colour, texture, construction, attachment size, packaging, order quantity and any custom development work.
A quotation for a 20-inch extension is not comparable unless the buyer also knows the net hair weight, end fullness, material definition, colour group and construction. A lighter product, a product with less fullness at the ends or a product using a less demanding colour route may carry the same nominal length while representing a different commercial product.

Before choosing a supplier, normalise these fields and use the same written request for every quotation. Our guide to comparing hair-extension quotations explains this process in detail.
