FDA-Cleared vs FDA-Approved: What It Means for Hair Devices

You'll see "FDA-approved" in a lot of hair-device marketing. It's wrong. iRestore, Capillus, Kiierr, HairMax and Theradome are all FDA-cleared, and the distinction matters.

Approval vs clearance

• FDA approval is for high-risk (Class III) devices and drugs. The maker must prove safety and effectiveness with its own clinical trials through a premarket approval (PMA) process.
• FDA clearance is for moderate-risk (Class II) devices through the 510(k) pathway. The maker shows the device is substantially equivalent to one already legally on the market, in intended use and technology.

Home laser hair devices are Class II, so clearance is the correct — and only — pathway for them.

What clearance does and doesn't tell you

Clearance tells you the FDA accepted the device as equivalent to a cleared predecessor for a stated use: treating androgenetic alopecia in adults with specific hair-loss patterns, often described using the Norwood and Ludwig scales. It does not rank devices against each other or guarantee a result for you.

How to check a device yourself

1. Search the FDA's 510(k) database for the brand name.
2. Look for the indications for use — who the device is cleared for.
3. Match the model you're buying to the model in the clearance.
