What is scalp galea?

The scalp galea is a layer of dense fibrous tissue located between the scalp skin and the underlying skull bone. It is a tough and protective layer that acts as a foundation for the attachment of the scalp muscles. The galea also provides a blood supply to the scalp, making it an essential part of wound healing and scalp reconstructive surgery. Scalp galea can be the site of infections such as dermatitis, which can cause itching, flaking, and hair loss. In addition, injuries to the galea can result in scalp lacerations, which may require suturing or reconstruction. A healthy scalp galea is crucial for maintaining healthy hair growth.
