Nanoparticles hitchhiking their way along strands of hair

In shampoo ads, hair always looks like a shiny, smooth surface. But for physicists peering into microscopes, the hair surface looks much more rugged, as it is made of saw-tooth, ratchet-like scales. In a new theoretical study published in EPJ E, Matthias Radtke and Roland Netz have demonstrated that massaging hair can help to apply drug treatment – encapsulated in nanoparticles trapped in the channels formed around individual hairs – to the hair roots. This is because the oscillatory movement of the massaging directs the way these particles are transported.

This phenomenon was previously discovered in experiments on pork skin samples, which were conducted by Jürgen Lademann, dermatologist at the Charité clinic in Berlin, Germany, and…
