Clear answers
Questions worth answering fully.
Does a higher diode count automatically mean better results?+
No. Diode count affects coverage and device design, but wavelength, power, dose, session protocol, adherence, and the evidence for the specific device also matter.
Are all four devices FDA cleared?+
The compared Regrowthy, iRestore Professional, Kiierr 272 Premier, and Capillus Pro listings identify the devices as FDA cleared. Clearance is not the same as FDA approval of a drug.
Why do the prices differ so much?+
Brand position, enclosure design, light source mix, session protocol, warranty, guarantee, accessories, and promotions all affect price. This page compares published specifications rather than assuming price proves efficacy.
Are the listed prices permanent?+
No. Competitor prices and promotions can change. The page states when the figures were checked and links each official product page.
