Experimental Study on the Use of Autogenous Hair Material for Injectable Soft Tissue Filler

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.
