I’m assuming that as with the rabid fear of ‘tropical’ oils in I think the 1950s or 60s, there’s probably somebody’s commercial interest behind this sudden rash of articles and the AHA seem to be mentioned in all of them. I smell the kind of wraparound coverage that you get when a PR firm somewhere have been hired to place stories with papers.
Like I said, my favourites complaint here was that using it cosmetically only has cosmetic results. I don’t think anybody using it on their hair or skin expects anything ther than cosmetic benefits. Is the maddest complaint I can think of. It’s like complaining that lipstick won’t make your lips red permanently. It just smacks of looking for something to complain about.
