Why no cap here has a dupe yet
For a device, a dupe on this site is one whose own 510(k) names the original as the device it is equivalent to, and costs at least 40% less. illumiflow's 272 cap names the Capillus 272 Pro, but costs about 18% less. Hubei YJT's helmets name both the Capillus 272 Pro and the iRestore Elite, under K253231, but on Amazon only a reseller sells them, and we don't link to resellers. The cheaper caps a brand does sell there either give no model number we could match or name other devices.
Questions
Which laser caps on Amazon are FDA-cleared?
7 that we matched to their own 510(k): iRestore Essential (K213094), iRestore Professional (K183417), illumiflow 272 Laser Cap (K162071), Theradome PRO LH80 (K171775), Capillus PRO (K163170), Hairmax PowerFlex 272 (K180885), iRestore Elite (K222081). Each is cleared to promote hair growth with androgenetic alopecia, in men at Norwood-Hamilton IIa to V and in women at Ludwig-Savin I to II.
What is the cheapest FDA-cleared laser cap on Amazon?
Of the caps we matched to a 510(k), the iRestore Essential, at $499 on Amazon today, cleared under K213094.
Is there a cheaper alternative to the iRestore Elite?
iRestore's own Essential, $499 against the Elite's $1899, cleared for the same use under K213094; the Elite has more light sources, 300 lasers and 200 diodes by its 510(k). No cheaper cap a brand sells on Amazon names the Elite as its equal: Hubei YJT's helmets do, under K253231, but only a reseller sells them there.
Do laser caps work for women?
They are cleared for both: every 510(k) here covers women with androgenetic alopecia at Ludwig-Savin I to II, and men at Norwood-Hamilton IIa to V, with skin types I to IV. Clearance means the FDA found each equivalent to a cap already sold for that use, not that it regrows hair for everyone.
How do I check whether a laser cap is FDA-cleared?
Search the FDA's 510(k) database by the brand or the model number on the listing. Caps under $100 on Amazon can say FDA-cleared with neither on the page; ask the seller for the K-number and look it up before you buy.
