Common questions
Which red light hat should I buy?
The RedLight Innovation Hat Pro, at £372, unless you specifically want the cheapest cap, a cordless-only routine, or a rigid helmet.
Why are there no star ratings?
The picks are the price, the spec and the research, set out so you can check them. Stars would not tell you anything extra.
Why are laser caps missing?
HairMax, Capillus and similar devices matter in the trials. Their place in the research is on the LED or laser page, alongside the UK prices checked on each brand’s own site.
