What the evidence shows
Low-level red light applied to the scalp has been studied for androgenetic alopecia, the common pattern hair loss in men and women, for more than a decade. Randomised trials using helmets, caps and combs emitting light at 630 to 680 nm have found increased hair counts compared with sham devices after 16 to 26 weeks of use, typically three times a week. Several such devices have regulatory clearance for this use. The effect is real but moderate: thicker, denser hair in areas that are thinning rather than regrowth on bald scalp, and it stops if you stop.
What it does not do
Red light has not been shown to help alopecia areata, scarring alopecia, or hair loss from thyroid disease, iron deficiency or medication. Those need the underlying cause treated. Nor does a whole-body session in a pod deliver a meaningful dose to hair follicles under hair; scalp devices sit directly against the skin for that reason.
How it is thought to work
Light absorbed by follicle cells increases cellular energy and blood flow, prolongs the growth phase of the hair cycle and may reduce the follicle miniaturisation that drives pattern hair loss. It works best in early to moderate thinning where follicles are still active.
Our position at Omnia
We offer NovoTHOR for recovery, pain, inflammation and skin, and we do not present it as a hair-loss treatment because the evidence for hair relates to scalp-specific devices. If hair loss is your concern, the useful first step is identifying the cause: a blood test for iron, thyroid and vitamin D through our Randox service, and a GP or dermatologist review for diagnosis. If pattern hair loss is confirmed, a clinically tested scalp device used consistently at home is a reasonable option alongside conventional treatments.
Realistic expectations
Four to six months before judging, several sessions a week, and continued use to maintain. Anyone promising regrowth in weeks is not describing the research.
