The other day, I came across a Radio 4 program which discussed caffeine shampoos.
Despite not coming to a strong conclusion on them, the rest of the program was quite interesting about hair growth in general.
Bit of a shame that, as so often, they manage to ignore thyroid issues. Despite mentioning some other factors.
Might be worth half an hour of listening in the background!
Caffeine Shampoo
Sliced Bread
Greg Foot and his guests put caffeine shampoo and other hair products through the evidence mill.
Can caffeine hair products prevent our hair from getting thinner as we get older and, even better, reverse the process? Or does this ingredient just end up going down the plughole? Joining Greg Foot in the studio is Ian Carmichael, Senior Director in Styling at Trevor Sorbie, the Hair Salon, who styles many high profile heads including Her Majesty the Queen’s. Dermatologist Dr Paul Farrant, from Brighton and Sussex University Hospitals Trust, is on hand to put two products through the evidence mill, separating the facts from the fads to reveal whether caffeine hair products really are The Best Thing Since Sliced Bread. Produced by Beth Eastwood.
