A cranial prosthesis, also known as a medical wig, is a custom-made wig designed to replace hair lost due to medical conditions or treatments like alopecia, chemotherapy, or other related conditions. Unlike traditional wigs, cranial prostheses are crafted to fit precisely, provide comfort, and be natural-looking. They are considered durable medical equipment and are often covered by insurance for hair loss due to medical reasons.

​

In essence, a cranial prosthesis is a medical wig that goes beyond basic aesthetics, providing a customized, comfortable, and medically necessary solution for individuals experiencing hair loss due to medical conditions or treatments. 

​

A cranial prosthesis and a wig are both designed to cover hair loss, but they differ in several key aspects:

​

• A medical device designed to address hair loss resulting from medical conditions such as chemotherapy, alopecia, or burns.  

• They are typically made from hypoallergenic and breathable materials, such as medical-grade silicone, human hair, or synthetic hair.  

• Custom-made to accurately fit the individual's head while providing comfort and support.  

• It is typically covered by health insurance as a medical expense device. 

• It can be more durable because of its medical-grade materials. 

• It can be designed with features that accommodate medical conditions, such as scalp sensitivities or drainage tubes. 

Wig:

• It can be made from a broader range of materials, including synthetic hair, human hair, or even lace.  

• Usually, they are pre-made in various styles and sizes, which may not always fit perfectly.

• Typically considered a cosmetic expense that is often not covered by insurance.  

• The durability depends on the materials used and the level of care provided.  

• It can be styled in various ways to achieve different looks.
