A hair prosthesis, hair system or medical wig is a non-surgical way to cover partial or extensive hair loss. It can be considered by people with alopecia, treatment-related hair loss, scarring conditions, limited donor hair, or those who simply do not want surgery.
What is a hair prosthesis?
Hair prostheses range from full wigs to partial systems designed to cover a specific area. They may use human hair, synthetic fibres or a combination, with different base materials and attachment methods. There is no single system that is automatically best for sensitive skin, an active lifestyle or every type of hair loss.
When can a non-surgical hair system be useful?
A prosthesis may be useful when someone wants immediate cosmetic coverage, is not a suitable transplant candidate, has insufficient donor hair, is experiencing temporary or treatment-related hair loss, or prefers a reversible option. It does not treat the biological cause of hair loss or stimulate follicles to regrow hair.
What should you check before choosing one?
- Whether the base and adhesive are suitable for your scalp and skin sensitivity.
- How the system is secured and how often it needs removal, cleaning or maintenance.
- Whether heat styling, colouring, swimming or exercise are compatible with the specific product.
- Expected lifespan, replacement needs and ongoing maintenance cost.
- Whether an underlying scalp or hair-loss condition still needs medical assessment.
Human hair does not mean maintenance-free
Some systems use human hair, but that does not mean they can always be treated exactly like growing hair. Colouring, heat, chemical products, washing and attachment methods can shorten the life of a system or irritate the scalp. Care instructions should be specific to the material and construction.
How does this differ from a hair transplant?
A prosthesis covers an area externally. A hair transplant redistributes a patient’s own donor follicles to selected recipient areas and requires appropriate donor supply, diagnosis and surgical planning. Neither approach is universally preferable; the decision depends on goals, cause of hair loss, donor availability, medical suitability and willingness to maintain the chosen option.
