Medical wigs and cranial prostheses
What a cranial prosthesis actually is, how it differs from a retail wig, the options available, and how to find someone to fit one.
What is a cranial prosthesis?
A cranial prosthesis is a wig or hair system prescribed by a physician for hair loss caused by a medical condition or its treatment. It is designed for a scalp that may be sensitive, bare, or healing, and because it is classified as a medical device rather than a cosmetic accessory, it may be eligible for insurance benefits.
- Also called a scalp hair prosthesis, full cranial prosthesis, or medical wig
- Prescribed for conditions such as alopecia, chemotherapy hair loss, and scarring hair loss
- Built for comfort and security on a sensitive or bare scalp, not just appearance
- Fitted by a trained Cranial Prosthesis Specialist rather than sold off a shelf
- HCPCS A9282 is the code commonly used when billing one to insurance
Medical wig vs regular wig
People often ask whether a cranial prosthesis is just an expensive wig. It is not, and the differences are the reason insurance treats them differently.
| Item | Cranial prosthesis (medical wig) | Retail wig |
|---|---|---|
| Why you have it | Medical hair loss documented by a physician | Style, fashion, convenience |
| How it is classified | Medical device, prescribed and billed as a cranial prosthesis | Cosmetic accessory |
| Cap construction | Built for a sensitive, bare, or healing scalp. Soft interiors, breathable bases, secure fit without tension | Built to sit on existing hair, often with combs or clips |
| Fit | Measured and fitted to your head by a trained specialist | Standard sizing, adjust it yourself |

What you can choose from
Your specialist will narrow these down with you based on your scalp, your condition, your hair history, your timeline, and your budget. You do not have to know which one you want before your consultation.
Human hair prostheses
Styled, coloured, and heat-treated like your own hair. The most natural movement and the longest lifespan with proper care, at a higher cost.
Synthetic prostheses
Hold their style through washing, weigh less, and cost less. A strong choice during active treatment when energy is limited.
Textured prostheses
Curl patterns and densities that match textured and coily hair, fitted by specialists who work with textured hair every day.
Custom cranial prostheses
Made to your measurements, your density, and your colour. The best fit and the longest lead time.
Ready-to-wear prostheses
Fitted and adjusted from stock. Far faster, and often the right call when treatment is starting soon.
Sensitive-scalp options
Soft, breathable, low-tension bases for scalps that are tender, healing, or reacting to treatment.
Lace and mono tops
Hand-tied fronts and monofilament tops that create a natural hairline and the appearance of hair growing from the scalp.
Toppers and partial systems
For diffuse thinning or partial loss where full coverage is not needed and blending with existing hair matters.
Who qualifies for a medical wig
Generally, anyone whose hair loss has a documented medical cause. The condition matters less than whether a physician can document it.
- Hair loss from cancer treatmentChemotherapy, radiation to the head, and other treatment-related loss.
- Alopecia areata, totalis, and universalisAutoimmune hair loss, whether patchy, complete on the scalp, or full body.
- Scarring hair lossCicatricial alopecia, CCCA, frontal fibrosing alopecia, and lichen planopilaris.
- Systemic and autoimmune conditionsLupus, thyroid disorders, and other conditions where hair loss is documented.
- Medication-induced hair lossWhere a prescribing physician can document the cause.
- Trauma, burns, and surgical lossWhere hair will not regrow in the affected area.
Qualifying is not the same as coverage
Having a qualifying condition means a cranial prosthesis is medically appropriate. Whether your insurance pays for it is a separate question that depends on your plan, state, documentation, and supplier status.
Questions about medical wigs
How much does a cranial prosthesis cost?
It depends on hair type, cap construction, density, and whether the unit is custom or ready-to-wear. Synthetic ready-to-wear units sit at the lower end and custom human hair units at the higher end. Your specialist gives you real numbers at your consultation, and Wig Medical tells you what portion your plan may cover before anything is ordered.
How long does a cranial prosthesis last?
With daily wear, synthetic units generally last several months to about a year, and human hair units can last considerably longer with proper care. Lifespan depends heavily on how often you wear it, how you wash and store it, and how much heat styling it gets. Your specialist will show you how to extend it.
Should I get it before treatment starts?
If you can, yes. Being fitted before hair loss begins means your specialist can match your natural colour, texture, and density directly, and it means you are not making decisions in the middle of treatment. Ready-to-wear options exist precisely for people who are already on a short timeline.
Will it look obvious?
Fitted properly, no. Lace fronts and monofilament tops create a natural hairline and the look of hair growing from the scalp, and a specialist adjusts density and cut to suit your face. Most of what makes a wig look like a wig is poor fit and wrong density, which is exactly what a fitting addresses.
Can I get one for textured or coily hair?
Yes. Textured cranial prostheses are a core part of what Wig Medical teaches, and many certified specialists work with textured hair routinely. Tell us your hair type when you start your case and we will take it into account.
Are there options for men?
Yes. Men's hair systems and cranial prostheses are available from certified specialists, including options for medical hair loss from treatment or alopecia. Mention it when you get in touch so we can point you to someone who fits men's systems.
