I need to do a hair test for MCFD and I relapsed after 3 years. Are there any real products that claim they will help you pass a hair test that actually work for real, and if so, how is that possible without being 100% or shaving your head?

They are all a scam and design to part the gullible from their cash.

To add, shaving your head appears as guilt and body hair will be used. If there is no body hair, fingernail scraping can be taken.

No one will help you cover your slip, that would be unethical.

No, there is no product that actually works. They only separate you from your money.

If you shave your hair, they will assume you are guilty and do much more detailed tests to determine. Also, they can also use hair from other places on your body.
