There are no matches on Google for ‘extensor molecules’. Quite reasonable, really, since no such thing exists. But according to the good people at Garnier in their new advert, these molecules are what makes their new shampoo so effective. OK, it may not be Garnier. It may be the people who encourage you to wear a bra on your head (see earlier PBS posts). How perplexing. I myself had a fun experience with shampoo science this morning, using Lush’s ‘black and white bar’ to wash my hair. Rubbing a great big bar on my head I did not feel like a hair pioneer, I felt like a wally. I am also not sure it has cleaned my greasy locks much. But it did smell nice.
