That's because the wigs and turbans are lent to palliative cancer patients across the region experiencing hair loss due to chemotherapy.

On Wednesday the library, set up by the Illawarra Palliative Care Volunteer Service at Port Kembla Hospital, was given a boost thanks to funds from the i98FM Illawarra Convoy.

The Illawarra Community Foundation has restocked the service with more than 100 new wigs, foam display heads and 119 new headpieces, valued at $18,000.

They'll provide more choice for patients staying on the palliative care ward, and those spending their final days at home.

"This is a very important service for patients encountering hair loss during treatment, which can be often overlooked for funding," foundation manager Mark Rigby said.

"We are proud to support this service and understand the importance of self-esteem during what is an extremely difficult time for patients and their families."

The palliative care volunteer service has been supporting patients at the Port Kembla Hospital ward for more than 20 years, with the wig library just one of the initiatives.

"It's terrific to see the change in patients when they have been fitted with a wig," service president Liz Inglis said. "Patients come in at their most vulnerable and go out feeling like a million dollars."

Ms Inglis welcomed the boost to the library, as the service has a return rate of around 40 per cent and stocks were dwindling.

She said this was common for wig libraries as when a patient died, their families had other issues on their minds while patients may also have wished to be buried with their wig.

Proceeds from Convoy also funded an additional $17,000 worth of equipment for the ward.

This included three oxygen concentrator systems for patients with breathing difficulties, and an active mattress to provide comfort and minimise bed sores. It also funded a chair sofa bed which can be used by families of those in palliative care.
