LLLT Hair Growth Studies: What Clinics Should Measure

Low-level laser therapy has been investigated as a non-invasive approach to androgenetic alopecia.

Published systematic reviews report improvements in hair-density outcomes in some randomised studies. However, clinical results depend on the studied population, device characteristics and treatment protocol.

Look beyond diode count

For trichologists evaluating a laser cap, the diode count alone is insufficient to establish clinical performance.

Wavelength, optical output, treatment duration, irradiance and the evidence for the exact device model all deserve consideration.

Match evidence to the device

A meaningful comparison should distinguish published findings about LLLT as a treatment category from claims established for a particular commercial device.

NovaClin Labs offers a 128-laser-diode hair cap. Model-specific specifications and regulatory documentation should be reviewed before making clinical performance claims.
