He is a frequent media spokesman, and has written about the importance placed in hair over the centuries and the fact that baldness until recently was not recognised as a social or medical issue, despite the sometimes catastrophic impact it can have on confidence and mental well-being. He wrote: "Male pattern baldness (MPB), the main cause of hair loss, affects an estimated quarter of men by the age of 30 and two thirds by the age of 60. Until recently, the impact baldness might have on confidence and well-being was little understood or recognised by the medical profession at large."

RBD prevalence as of 2017 is estimated to be 0.5–2% overall, and 5–13% of those aged 60 to 99. It is more common in males overall, but equally frequent among men and women below the age of 50. This may partially be due to a referral bias, as violent activity carried out by men is more likely to result in harm and injury and is more likely to be reported than injury to male bed partners by women, or it may reflect a true difference in prevalence as a result of genetic or androgenic factors. Typical onset is in the 50s or 60s.
