The study investigated the use of autogenous rabbit hair as an injectable soft tissue filler, focusing on different preparation methods. Four types of materials were created, with type D using hair keratin glue and types A, B, and C being powdered homogenates ground for varying durations. Results showed that all materials were injectable, but type D had a more pronounced histological reaction and faster absorption rate. Types A, B, and C had slower absorption rates and more evident fibrous proliferation, with type A forming the thickest fibrous capsule. The study concluded that the material ground for 8 hours (type B) demonstrated better suitability, adaptivity, and histocompatibility, suggesting its potential as a new injectable soft tissue filler.
