In a large hall-size production unit of the Evergreen Products Factory (EPF), a group of women twist silky hair on mannequin heads. They form braids in halo, Fulani, crochet, Ghana or cornrow styles.

Carefully, others comb the permed, dyed hair. This is a traditional exhibition of Bangladeshi village women, doing hairdressing for their daughters or sisters during their leisure time in their courtyards.

They also have male companions drawing bunches of unbundled hair through hair hackles clamped to workbenches.

The Evergreen workers, mostly hailing from the impoverished northern villages, have no spare time for volunteer hairdressing. In Uttara Export Processing Zone, Nilphamari, they manufacture hair products for foreign buyers. 

According to EPF Chairman Felix Y.C. Chang, Evergreen manufactures three million pieces of hair products monthly.

"Our major export destinations are the United States, European Union countries, South Africa, Japan, and China. Currently, Evergreen is among the top producers in the world," Felix said.

EPF operates on nearly 38,000 square metres of space in the Uttara EPZ. The company employs around 11,000 workers – one-third of the total workforce in this industrial colony.

Given the designs and orders by international buyers, EPF manufactures and sells a wide range of hair products like: wigs, hair pieces, braids, and high-end human hair extensions.

As Halloween celebrations and cosplay culture have become more popular across the world, the EPF deals with a large number of orders for beauty hair products.
